## STM32F10x CMSIS update History

### 3.3.0 - 04/16/2010

1. General

- Add support for STM32F10x XL-density devices.
- Add startup files for TrueSTUDIO toolchain

2. STM32F10x CMSIS Device Peripheral Access Layer

- STM32F10x CMSIS Cortex-M3 Device Peripheral Access Layer Header File: stm32f10x.h

- Update to support XL-density devices

- Add new define STM32F10X_XL

- Add new IRQs for TIM9..14
- Update FLASH_TypeDef structure
- Add new IP instances TIM9..14
- RCC, AFIO, DBGMCU bits definition updated

- Correct IRQs definition for MD-, LD-, MD_VL- and LD_VL-density devices (remove comma "," at the end of enum list)

- STM32F10x CMSIS Cortex-M3 Device Peripheral Access Layer System Files: system_stm32f10x.h and system_stm32f10x.c

- SystemInit_ExtMemCtl() function: update to support XL-density devices
- SystemInit() function: swap the order of SetSysClock() and SystemInit_ExtMemCtl() functions.

- STM32F10x CMSIS startup files:

- add three startup files for STM32 XL-density devices: startup_stm32f10x_xl.s
- startup_stm32f10x_md_vl.s for RIDE7: add USART3 IRQ Handler (was missing in previous version)
- Add startup files for TrueSTUDIO toolchain

### 3.2.0 - 03/01/2010

1. General

- STM32F10x CMSIS files updated to CMSIS V1.30 release
- Directory structure updated to be aligned with CMSIS V1.30
- Add support for STM32 Low-density Value line (STM32F100x4/6) and Medium-density Value line (STM32F100x8/B) devices.

2. CMSIS Core Peripheral Access Layer

- Refer to CMSIS changes

3. STM32F10x CMSIS Device Peripheral Access Layer

- STM32F10x CMSIS Cortex-M3 Device Peripheral Access Layer Header File: stm32f10x.h

- Update the stm32f10x.h file to support new Value line devices features: CEC peripheral, new General purpose timers TIM15, TIM16 and TIM17.
- Peripherals Bits definitions updated to be in line with Value line devices available features.
- HSE_Value, HSI_Value and HSEStartup_TimeOut changed to upper case: HSE_VALUE, HSI_VALUE and HSE_STARTUP_TIMEOUT. Old names are kept for legacy purposes.

- STM32F10x CMSIS Cortex-M3 Device Peripheral Access Layer System Files: system_stm32f10x.h and system_stm32f10x.c

- SystemFrequency variable name changed to SystemCoreClock
- Default SystemCoreClock is changed to 24MHz when Value line devices are selected and to 72MHz on other devices.
- All while(1) loop were removed from all clock setting functions. User has to handle the HSE startup failure.
- Additional function void SystemCoreClockUpdate (void) is provided.

- STM32F10x CMSIS Startup files: startup_stm32f10x_xx.s

- Add new startup files for STM32 Low-density Value line devices: startup_stm32f10x_ld_vl.s
- Add new startup files for STM32 Medium-density Value line devices: startup_stm32f10x_md_vl.s
- SystemInit() function is called from startup file (startup_stm32f10x_xx.s) before to branch to application main.
  To reconfigure the default setting of SystemInit() function, refer to system_stm32f10x.c file
- GNU startup file for Low density devices (startup_stm32f10x_ld.s) is updated to fix compilation errors.
