Changes to CMSIS version V1.20

- -

1. Removed CMSIS Middelware packages

- CMSIS Middleware is on hold from ARM side until a agreement between all CMSIS partners is found. -

- -

2. SystemFrequency renamed to SystemCoreClock

- The variable name SystemCoreClock is more precise than SystemFrequency - because the variable holds the clock value at which the core is running. -

- -

3. Changed startup concept

- The old startup concept (calling SystemInit_ExtMemCtl from startup file and calling SystemInit - from main) has the weakness that it does not work for controllers which need a already - configuerd clock system to configure the external memory controller. -

- -

Changed startup concept

- SystemInit() is called from startup file before premain. -
- SystemInit() configures the clock system and also configures - an existing external memory controller. -
- SystemInit() must not use global variables. -
- SystemCoreClock is initialized with a correct predefined value. -
- Additional function void SystemCoreClockUpdate (void) is provided.
- SystemCoreClockUpdate() updates the variable SystemCoreClock - and must be called whenever the core clock is changed.
- SystemCoreClockUpdate() evaluates the clock register settings and calculates - the current core clock. -

- - -

4. Advanced Debug Functions

- ITM communication channel is only capable for OUT direction. To allow also communication for - IN direction a simple concept is provided. -

- Global variable volatile int ITM_RxBuffer used for IN data. -
- Function int ITM_CheckChar (void) checks if a new character is available. -
- Function int ITM_ReceiveChar (void) retrieves the new character. -

- -

- For detailed explanation see file CMSIS debug support.htm. -

- - -

5. Core Register Bit Definitions

- Files core_cm3.h and core_cm0.h contain now bit definitions for Core Registers. The name for the - defines correspond with the Cortex-M Technical Reference Manual. -

- e.g. SysTick structure with bit definitions -

-/** @addtogroup CMSIS_CM3_SysTick CMSIS CM3 SysTick

7. DoxyGen Tags

- DoxyGen tags in files core_cm3.[c,h] and core_cm0.[c,h] are reworked to create proper documentation - using DoxyGen. -

- -

8. Folder Structure

- The folder structure is changed to differentiate the single support packages. -

9. Open Points

- Following points need to be clarified and solved: -

-
- Equivalent C and Assembler startup files. -
-
- Is there a need for having C startup files although assembler startup files are - very efficient and do not need to be changed? -
-
-
- Placing of HEAP in external RAM. -
-
- It must be possible to place HEAP in external RAM if the device supports an - external memory controller. -
-
-
- Placing of STACK /HEAP. -
-
- STACK should always be placed at the end of internal RAM. -
-
- If HEAP is placed in internal RAM than it should be placed after RW ZI section. -
-
-
- Removing core_cm3.c and core_cm0.c. -
-
- On a long term the functions in core_cm3.c and core_cm0.c must be replaced with - appropriate compiler intrinsics. -
-

- - -

10. Limitations

- The following limitations are not covered with the current CMSIS version: -

- No C startup files for ARM toolchain are provided. -
- No C startup files for GNU toolchain are provided. -
- No C startup files for IAR toolchain are provided. -
- No Tasking projects are provided yet. -

CMSIS Debug Support

- -

Cortex-M3 ITM Debug Access

- The Cortex-M3 incorporates the Instrumented Trace Macrocell (ITM) that provides together with - the Serial Viewer Output trace capabilities for the microcontroller system. The ITM has - 32 communication channels which are able to transmit 32 / 16 / 8 bit values; two ITM - communication channels are used by CMSIS to output the following information: -

ITM Channel 0: used for printf-style output via the debug interface.
ITM Channel 31: is reserved for RTOS kernel awareness debugging.

- -

Debug IN / OUT functions

CMSIS provides following debug functions:

ITM_SendChar (uses ITM channel 0)
ITM_ReceiveChar (uses global variable)
ITM_CheckChar (uses global variable)

- -

ITM_SendChar

- ITM_SendChar is used to transmit a character over ITM channel 0 from - the microcontroller system to the debug system.
- Only a 8 bit value is transmitted. -

-static __INLINE uint32_t ITM_SendChar (uint32_t ch)
-{
-  /* check if debugger connected and ITM channel enabled for tracing */
-  if ((CoreDebug->DEMCR & CoreDebug_DEMCR_TRCENA)  &&
-      (ITM->TCR & ITM_TCR_ITMENA)                  &&
-      (ITM->TER & (1UL << 0))  ) 
-  {
-    while (ITM->PORT[0].u32 == 0);
-    ITM->PORT[0].u8 = (uint8_t)ch;
-  }  
-  return (ch);
-}

- -

ITM_ReceiveChar

- ITM communication channel is only capable for OUT direction. For IN direction - a globel variable is used. A simple mechansim detects if a character is received. - The project to test need to be build with debug information. -

- -

- The globale variable ITM_RxBuffer is used to transmit a 8 bit value from debug system - to microcontroller system. ITM_RxBuffer is 32 bit wide to enshure a proper handshake. -

-extern volatile int ITM_RxBuffer;                    /* variable to receive characters                             */
-

- A dedicated bit pattern is used to determin if ITM_RxBuffer is empty - or contains a valid value. -

-#define             ITM_RXBUFFER_EMPTY    0x5AA55AA5 /* value identifying ITM_RxBuffer is ready for next character */
-

- ITM_ReceiveChar is used to receive a 8 bit value from the debug system. The function is nonblocking. - It returns the received character or '-1' if no character was available. -

-static __INLINE int ITM_ReceiveChar (void) {
-  int ch = -1;                               /* no character available */
-
-  if (ITM_RxBuffer != ITM_RXBUFFER_EMPTY) {
-    ch = ITM_RxBuffer;
-    ITM_RxBuffer = ITM_RXBUFFER_EMPTY;       /* ready for next character */
-  }
-  
-  return (ch); 
-}
-

- -

ITM_CheckChar

- ITM_CheckChar is used to check if a character is received. -

-static __INLINE int ITM_CheckChar (void) {
-
-  if (ITM_RxBuffer == ITM_RXBUFFER_EMPTY) {
-    return (0);                                 /* no character available */
-  } else {
-    return (1);                                 /*    character available */
-  }
-}

- - -

ITM Debug Support in uVision

- uVision uses in a debug session the Debug (printf) Viewer window to - display the debug data. -

Direction microcontroller system -> uVision:

- Characters received via ITM communication channel 0 are written in a printf style - to Debug (printf) Viewer window. -

- -

Direction uVision -> microcontroller system:

Check if ITM_RxBuffer variable is available (only performed once).
Read character from Debug (printf) Viewer window.
If ITM_RxBuffer empty write character to ITM_RxBuffer.

- -

Note

Current solution does not use a buffer machanism for trasmitting the characters.
-

- -

RTX Kernel awareness in uVision

- uVision / RTX are using a simple and efficient solution for RTX Kernel awareness. - No format overhead is necessary.
- uVsion debugger decodes the RTX events via the 32 / 16 / 8 bit ITM write access - to ITM communication channel 31. -

- -

Following RTX events are traced:

Task Create / Delete event -
1. 32 bit access. Task start address is transmitted
2. 16 bit access. Task ID and Create/Delete flag are transmitted
  - High byte holds Create/Delete flag, Low byte holds TASK ID. -
-
Task switch event -
1. 8 bit access. Task ID of current task is transmitted
-

- -

About

- -

- The Cortex Microcontroller Software Interface Standard (CMSIS) answers the challenges - that are faced when software components are deployed to physical microcontroller devices based on a - Cortex-M0 or Cortex-M3 processor. The CMSIS will be also expanded to future Cortex-M - processor cores (the term Cortex-M is used to indicate that). The CMSIS is defined in close co-operation - with various silicon and software vendors and provides a common approach to interface to peripherals, - real-time operating systems, and middleware components. -

- -

ARM provides as part of the CMSIS the following software layers that are -available for various compiler implementations:

Core Peripheral Access Layer: contains name definitions, - address definitions and helper functions to - access core registers and peripherals. It defines also a device - independent interface for RTOS Kernels that includes debug channel - definitions.

- -

These software layers are expanded by Silicon partners with:

Device Peripheral Access Layer: provides definitions - for all device peripherals
Access Functions for Peripherals (optional): provides - additional helper functions for peripherals

- -

CMSIS defines for a Cortex-M Microcontroller System:

A common way to access peripheral registers - and a common way to define exception vectors.
The register names of the Core - Peripherals and the names of the Core - Exception Vectors.
An device independent interface for RTOS Kernels including a debug - channel.

- -

- By using CMSIS compliant software components, the user can easier re-use template code. - CMSIS is intended to enable the combination of software components from multiple middleware vendors. -

- -

Coding Rules and Conventions

- -

- The following section describes the coding rules and conventions used in the CMSIS - implementation. It contains also information about data types and version number information. -

- -

Essentials

The CMSIS C code conforms to MISRA 2004 rules. In case of MISRA violations, - there are disable and enable sequences for PC-LINT inserted.
ANSI standard data types defined in the ANSI C header file - <stdint.h> are used.
#define constants that include expressions must be enclosed by - parenthesis.
Variables and parameters have a complete data type.
All functions in the Core Peripheral Access Layer are - re-entrant.
The Core Peripheral Access Layer has no blocking code - (which means that wait/query loops are done at other software layers).
For each exception/interrupt there is definition for: -
- an exception/interrupt handler with the postfix _Handler - (for exceptions) or _IRQHandler (for interrupts).
- a default exception/interrupt handler (weak definition) that contains an endless loop.
- a #define of the interrupt number with the postfix _IRQn.

- -

Recommendations

- -

The CMSIS recommends the following conventions for identifiers.

CAPITAL names to identify Core Registers, Peripheral Registers, and CPU Instructions.
CamelCase names to identify peripherals access functions and interrupts.
PERIPHERAL_ prefix to identify functions that belong to specify peripherals.
Doxygen comments for all functions are included as described under Function Comments below.

- -Comments - -

Comments use the ANSI C90 style (/* comment */) or C++ style - (// comment). It is assumed that the programming tools support today - consistently the C++ comment style.

Function Comments provide for each function the following information: -

one-line brief function overview.
detailed parameter explanation.
detailed information about return values.
detailed description of the actual function.

Doxygen Example:

-/** 
- * @brief  Enable Interrupt in NVIC Interrupt Controller
- * @param  IRQn  interrupt number that specifies the interrupt
- * @return none.
- * Enable the specified interrupt in the NVIC Interrupt Controller.
- * Other settings of the interrupt such as priority are not affected.
- */

- -

Data Types and IO Type Qualifiers

- -

- The Cortex-M HAL uses the standard types from the standard ANSI C header file - <stdint.h>. IO Type Qualifiers are used to specify the access - to peripheral variables. IO Type Qualifiers are indented to be used for automatic generation of - debug information of peripheral registers. -

- - - - - - - - - - - - - - - - - - - - - - - - -

IO Type Qualifier	#define	Description
__I	volatile const	Read access only
__O	volatile	Write access only
__IO	volatile	Read and write access

- -

CMSIS Version Number

- File core_cm3.h contains the version number of the CMSIS with the following define: -

-#define __CM3_CMSIS_VERSION_SUB   (0x30)      /* [15:0]  sub version        */
-#define __CM3_CMSIS_VERSION       ((__CM3_CMSIS_VERSION_MAIN << 16) | __CM3_CMSIS_VERSION_SUB)

- -

- File core_cm0.h contains the version number of the CMSIS with the following define: -

-
Interrupt Number Definition: provides interrupt numbers - (IRQn) for all core and device specific exceptions and interrupts.
-
-
Configuration for core_cm0.h / core_cm3.h: reflects the - actual configuration of the Cortex-M processor that is part of the actual - device. As such the file core_cm0.h / core_cm3.h is included that - implements access to processor registers and core peripherals.
-
-
Device Peripheral Access Layer: provides definitions - for all device peripherals. It contains all data structures and the address - mapping for the device specific peripherals.

Access Functions may be provided as inline functions - or can be extern references to a device specific library provided by the - silicon vendor.

- - -

Interrupt Number Definition

- -

To access the device specific interrupts the device.h file defines IRQn -numbers for the complete device using a enum typedef as shown below:

-typedef enum IRQn

Device Peripheral Access Layer

- Each peripheral uses a prefix which consists of <device abbreviation>_ - and <peripheral name>_ to identify peripheral registers that access this - specific peripheral. The intention of this is to avoid name collisions caused - due to short names. If more than one peripheral of the same type exists, - identifiers have a postfix (digit or letter). For example: -

<device abbreviation>_UART_Type: defines the generic register layout for all UART channels in a device. -

-typedef struct
-{
-  union {
-  __I  uint8_t  RBR;                     /*!< Offset: 0x000   Receiver Buffer Register    */

-#define LPC_UART3             ((LPC_UART_TypeDef      *) LPC_UART3_BASE    )
```

Minimal Requiements

- To access the peripheral registers and related function in a device the files device.h - and core_cm0.h / core_cm3.h defines as a minimum: -

The Register Layout Typedef for each peripheral that defines all register names. - Names that start with RESERVE are used to introduce space into the structure to adjust the addresses of - the peripheral registers. For example: -

-typedef struct {
-  __IO uint32_t CTRL;      /* SysTick Control and Status Register */
-  __IO uint32_t LOAD;      /* SysTick Reload Value Register       */
-  __IO uint32_t VAL;       /* SysTick Current Value Register      */
-  __I  uint32_t CALIB;     /* SysTick Calibration Register        */
-  } SysTick_Type;

- Base Address for each peripheral (in case of multiple peripherals - that use the same register layout typedef multiple base addresses are defined). For example: -
```
-#define SysTick_BASE (SCS_BASE + 0x0010)            /* SysTick Base Address */
```
-
- Access Definition for each peripheral (in case of multiple peripherals that use - the same register layout typedef multiple access definitions exist, i.e. LPC_UART0, - LPC_UART2). For Example: -
```
-#define SysTick ((SysTick_Type *) SysTick_BASE)     /* SysTick access definition */
```
-

- -

- These definitions allow to access the peripheral registers from user code with simple assignments like: -

SysTick->CTRL = 0;

- -

Optional Features

In addition the device.h file may define:

- #define constants that simplify access to the peripheral registers. - These constant define bit-positions or other specific patterns are that required for the - programming of the peripheral registers. The identifiers used start with - <device abbreviation>_ and <peripheral name>_. - It is recommended to use CAPITAL letters for such #define constants. -
- Functions that perform more complex functions with the peripheral (i.e. status query before - a sending register is accessed). Again these function start with - <device abbreviation>_ and <peripheral name>_. -

- -

core_cm0.h and core_cm0.c

- File core_cm0.h describes the data structures for the Cortex-M0 core peripherals and does - the address mapping of this structures. It also provides basic access to the Cortex-M0 core registers - and core peripherals with efficient functions (defined as static inline). -

- File core_cm0.c defines several helper functions that access processor registers. -

Together these files implement the Core Peripheral Access Layer for a Cortex-M0.

- -

core_cm3.h and core_cm3.c

- File core_cm3.h describes the data structures for the Cortex-M3 core peripherals and does - the address mapping of this structures. It also provides basic access to the Cortex-M3 core registers - and core peripherals with efficient functions (defined as static inline). -

- File core_cm3.c defines several helper functions that access processor registers. -

Together these files implement the Core Peripheral Access Layer for a Cortex-M3.

- -

startup_device

- A template file for startup_device is provided by ARM for each supported - compiler. It is adapted by the silicon vendor to include interrupt vectors for all device specific - interrupt handlers. Each interrupt handler is defined as weak function - to an dummy handler. Therefore the interrupt handler can be directly used in application software - without any requirements to adapt the startup_device file. -

- The following exception names are fixed and define the start of the vector table for a Cortex-M0: -

-__Vectors       DCD     __initial_sp              ; Top of Stack
-                DCD     Reset_Handler             ; Reset Handler

-                DCD     SysTick_Handler           ; SysTick Handler

- The following exception names are fixed and define the start of the vector table for a Cortex-M3: -

-__Vectors       DCD     __initial_sp              ; Top of Stack
-                DCD     Reset_Handler             ; Reset Handler

-                DCD     SysTick_Handler           ; SysTick Handler

- -

- In the following examples for device specific interrupts are shown: -

-; External Interrupts
-                DCD     WWDG_IRQHandler           ; Window Watchdog
-                DCD     PVD_IRQHandler            ; PVD through EXTI Line detect
-                DCD     TAMPER_IRQHandler         ; Tamper

- -

- Device specific interrupts must have a dummy function that can be overwritten in user code. - Below is an example for this dummy function. -

-Default_Handler PROC
-                EXPORT WWDG_IRQHandler   [WEAK]
-                EXPORT PVD_IRQHandler    [WEAK]
-                EXPORT TAMPER_IRQHandler [WEAK]
-                :
-                :
-                WWDG_IRQHandler
-                PVD_IRQHandler
-                TAMPER_IRQHandler
-                :
-                :
-                B .
-                ENDP

- -

- The user application may simply define an interrupt handler function by using the handler name - as shown below. -

-void WWDG_IRQHandler(void)
-{
-  :
-  :
-}

- - -

system_device.c

- A template file for system_device.c is provided by ARM but adapted by - the silicon vendor to match their actual device. As a minimum requirement - this file must provide a device specific system configuration function and a global variable - that contains the system frequency. It configures the device and initializes typically the - oscillator (PLL) that is part of the microcontroller device. -

- The file system_device.c must provide - as a minimum requirement the SystemInit function as shown below. -

NVIC Access Functions

- The CMSIS provides access to the NVIC via the register interface structure and several helper - functions that simplify the setup of the NVIC. The CMSIS HAL uses IRQ numbers (IRQn) to - identify the interrupts. The first device interrupt has the IRQn value 0. Therefore negative - IRQn values are used for processor core exceptions. -

- For the IRQn values of core exceptions the file device.h provides - the following enum names. -

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

The following function is used to configure the SysTick timer and start the -SysTick interrupt.

- - - - - - - - - - - - - - -

Name	Parameter	Description
uint32_t SysTickConfig - (uint32_t ticks)	ticks is SysTick counter reload value	Setup the SysTick timer and enable the SysTick interrupt. After this - call the SysTick timer creates interrupts with the specified time - interval. - - Return: 0 when successful, 1 on failure. -

Cortex-M3 ITM Debug Access

- -

The Cortex-M3 incorporates the Instrumented Trace Macrocell (ITM) that -provides together with the Serial Viewer Output trace capabilities for the -microcontroller system. The ITM has 32 communication channels; two ITM -communication channels are used by CMSIS to output the following information:

ITM Channel 0: implements the ITM_SendChar function - which can be used for printf-style output via the debug interface.
ITM Channel 31: is reserved for the RTOS kernel and can be used for - kernel awareness debugging.

Note

The ITM channel 31 is selected for the RTOS kernel since some kernels - may use the Privileged level for program execution. ITM - channels have 4 groups with 8 channels each, whereby each group can be - configured for access rights in the Unprivileged level. The ITM channel 0 - may be therefore enabled for the user task whereas ITM channel 31 may be - accessible only in Privileged level from the RTOS kernel itself.
-

- -

The prototype of the ITM_SendChar routine is shown in the -table below.

- - - - - - - - - - - - - - -

Name	Parameter	Description
void uint32_t ITM_SendChar(uint32_t chr)	character to output	The function outputs a character via the ITM channel 0. The - function returns when no debugger is connected that has booked the - output. It is blocking when a debugger is connected, but the - previous character send is not transmitted. - Return: the input character 'chr'.

- -

- Example for the usage of the ITM Channel 31 for RTOS Kernels: -

-  // check if debugger connected and ITM channel enabled for tracing
-  if ((CoreDebug->DEMCR & CoreDebug_DEMCR_TRCENA) &&
-  (ITM->TCR & ITM_TCR_ITMENA) &&
-  (ITM->TER & (1UL << 31))) {
-    // transmit trace data
-    while (ITM->PORT31_U32 == 0);
-    ITM->PORT[31].u8 = task_id;      // id of next task
-    while (ITM->PORT[31].u32 == 0);
-    ITM->PORT[31].u32 = task_status; // status information
-  }

Cortex-M3 additional Debug Access

- -

CMSIS provides additional debug functions to enlarge the Cortex-M3 Debug Access. -Data can be transmitted via a certain global buffer variable towards the target system.

- -

The buffer variable and the prototypes of the additional functions are shown in the -table below.

- - - - - - - - - - - - - - - - - - - - - - - - -

Name	Parameter	Description
extern volatile int ITM_RxBuffer		Buffer to transmit data towards debug system. - Value 0x5AA55AA5 indicates that buffer is empty.
int ITM_ReceiveChar (void)	none	The nonblocking functions returns the character stored in - ITM_RxBuffer. - Return: -1 indicates that no character was received.
int ITM_CheckChar (void)	none	The function checks if a character is available in ITM_RxBuffer. - Return: 1 indicates that a character is available, 0 indicates that - no character is available.
