Removed CMSIS Middelware packages</h2> -<p> - CMSIS Middleware is on hold from ARM side until a agreement between all CMSIS partners is found. -</p> - -<h2>2. SystemFrequency renamed to SystemCoreClock</h2> -<p> - The variable name <strong>SystemCoreClock</strong> is more precise than <strong>SystemFrequency</strong> - because the variable holds the clock value at which the core is running. -</p> - -<h2>3. Changed startup concept</h2> -<p> - 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. -</p> - -<h3>Changed startup concept</h3> -<ul> - <li> - SystemInit() is called from startup file before <strong>premain</strong>. - </li> - <li> - <strong>SystemInit()</strong> configures the clock system and also configures - an existing external memory controller. - </li> - <li> - <strong>SystemInit()</strong> must not use global variables. - </li> - <li> - <strong>SystemCoreClock</strong> is initialized with a correct predefined value. - </li> - <li> - Additional function <strong>void SystemCoreClockUpdate (void)</strong> is provided.<br> - <strong>SystemCoreClockUpdate()</strong> updates the variable <strong>SystemCoreClock</strong> - and must be called whenever the core clock is changed.<br> - <strong>SystemCoreClockUpdate()</strong> evaluates the clock register settings and calculates - the current core clock. - </li> -</ul> - - -<h2>4. Advanced Debug Functions</h2> -<p> - ITM communication channel is only capable for OUT direction. To allow also communication for - IN direction a simple concept is provided. -</p> -<ul> - <li> - Global variable <strong>volatile int ITM_RxBuffer</strong> used for IN data. - </li> - <li> - Function <strong>int ITM_CheckChar (void)</strong> checks if a new character is available. - </li> - <li> - Function <strong>int ITM_ReceiveChar (void)</strong> retrieves the new character. - </li> -</ul> - -<p> - For detailed explanation see file <strong>CMSIS debug support.htm</strong>. -</p> - - -<h2>5. Core Register Bit Definitions</h2> -<p> - 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. -</p> -<p> - e.g. SysTick structure with bit definitions -</p> -<pre> -/** @addtogroup CMSIS_CM3_SysTick CMSIS CM3 SysTick - memory mapped structure for SysTick - @{ - */ -typedef struct -{ - __IO uint32_t CTRL; /*!< Offset: 0x00 SysTick Control and Status Register */ - __IO uint32_t LOAD; /*!< Offset: 0x04 SysTick Reload Value Register */ - __IO uint32_t VAL; /*!< Offset: 0x08 SysTick Current Value Register */ - __I uint32_t CALIB; /*!< Offset: 0x0C SysTick Calibration Register */ -} SysTick_Type; - -/* SysTick Control / Status Register Definitions */ -#define SysTick_CTRL_COUNTFLAG_Pos 16 /*!< SysTick CTRL: COUNTFLAG Position */ -#define SysTick_CTRL_COUNTFLAG_Msk (1ul << SysTick_CTRL_COUNTFLAG_Pos) /*!< SysTick CTRL: COUNTFLAG Mask */ - -#define SysTick_CTRL_CLKSOURCE_Pos 2 /*!< SysTick CTRL: CLKSOURCE Position */ -#define SysTick_CTRL_CLKSOURCE_Msk (1ul << SysTick_CTRL_CLKSOURCE_Pos) /*!< SysTick CTRL: CLKSOURCE Mask */ - -#define SysTick_CTRL_TICKINT_Pos 1 /*!< SysTick CTRL: TICKINT Position */ -#define SysTick_CTRL_TICKINT_Msk (1ul << SysTick_CTRL_TICKINT_Pos) /*!< SysTick CTRL: TICKINT Mask */ - -#define SysTick_CTRL_ENABLE_Pos 0 /*!< SysTick CTRL: ENABLE Position */ -#define SysTick_CTRL_ENABLE_Msk (1ul << SysTick_CTRL_ENABLE_Pos) /*!< SysTick CTRL: ENABLE Mask */ - -/* SysTick Reload Register Definitions */ -#define SysTick_LOAD_RELOAD_Pos 0 /*!< SysTick LOAD: RELOAD Position */ -#define SysTick_LOAD_RELOAD_Msk (0xFFFFFFul << SysTick_LOAD_RELOAD_Pos) /*!< SysTick LOAD: RELOAD Mask */ - -/* SysTick Current Register Definitions */ -#define SysTick_VAL_CURRENT_Pos 0 /*!< SysTick VAL: CURRENT Position */ -#define SysTick_VAL_CURRENT_Msk (0xFFFFFFul << SysTick_VAL_CURRENT_Pos) /*!< SysTick VAL: CURRENT Mask */ - -/* SysTick Calibration Register Definitions */ -#define SysTick_CALIB_NOREF_Pos 31 /*!< SysTick CALIB: NOREF Position */ -#define SysTick_CALIB_NOREF_Msk (1ul << SysTick_CALIB_NOREF_Pos) /*!< SysTick CALIB: NOREF Mask */ - -#define SysTick_CALIB_SKEW_Pos 30 /*!< SysTick CALIB: SKEW Position */ -#define SysTick_CALIB_SKEW_Msk (1ul << SysTick_CALIB_SKEW_Pos) /*!< SysTick CALIB: SKEW Mask */ - -#define SysTick_CALIB_TENMS_Pos 0 /*!< SysTick CALIB: TENMS Position */ -#define SysTick_CALIB_TENMS_Msk (0xFFFFFFul << SysTick_VAL_CURRENT_Pos) /*!< SysTick CALIB: TENMS Mask */ -/*@}*/ /* end of group CMSIS_CM3_SysTick */</pre> - -<h2>7. DoxyGen Tags</h2> -<p> - DoxyGen tags in files core_cm3.[c,h] and core_cm0.[c,h] are reworked to create proper documentation - using DoxyGen. -</p> - -<h2>8. Folder Structure</h2> -<p> - The folder structure is changed to differentiate the single support packages. -</p> - - <ul> - <li>CM0</li> - <li>CM3 - <ul> - <li>CoreSupport</li> - <li>DeviceSupport</li> - <ul> - <li>Vendor - <ul> - <li>Device - <ul> - <li>Startup - <ul> - <li>Toolchain</li> - <li>Toolchain</li> - <li>...</li> - </ul> - </li> - </ul> - </li> - <li>Device</li> - <li>...</li> - </ul> - </li> - <li>Vendor</li> - <li>...</li> - </ul> - </li> - <li>Example - <ul> - <li>Toolchain - <ul> - <li>Device</li> - <li>Device</li> - <li>...</li> - </ul> - </li> - <li>Toolchain</li> - <li>...</li> - </ul> - </li> - </ul> - </li> - - <li>Documentation</li> - </ul> - -<h2>9. Open Points</h2> -<p> - Following points need to be clarified and solved: -</p> -<ul> - <li> - <p> - Equivalent C and Assembler startup files. - </p> - <p> - Is there a need for having C startup files although assembler startup files are - very efficient and do not need to be changed? - <p/> - </li> - <li> - <p> - Placing of HEAP in external RAM. - </p> - <p> - It must be possible to place HEAP in external RAM if the device supports an - external memory controller. - </p> - </li> - <li> - <p> - Placing of STACK /HEAP. - </p> - <p> - STACK should always be placed at the end of internal RAM. - </p> - <p> - If HEAP is placed in internal RAM than it should be placed after RW ZI section. - </p> - </li> - <li> - <p> - Removing core_cm3.c and core_cm0.c. - </p> - <p> - On a long term the functions in core_cm3.c and core_cm0.c must be replaced with - appropriate compiler intrinsics. - </p> - </li> -</ul> - - -<h2>10. Limitations</h2> -<p> - The following limitations are not covered with the current CMSIS version: -</p> -<ul> - <li> - No <strong>C startup files</strong> for ARM toolchain are provided. - </li> - <li> - No <strong>C startup files</strong> for GNU toolchain are provided. - </li> - <li> - No <strong>C startup files</strong> for IAR toolchain are provided. - </li> - <li> - No <strong>Tasking</strong> projects are provided yet. - </li> -</ul> |
