What's New in MDKARM Version 3.21 [Board Support] Added support for CQ_STARM32 board in folder ..\ARM\Boards\ST\CQ-STARM2. [RTX Debugging] Added support for RTX Event Viewer on Cortex-M3 based devices. [ULINK Support] Added MCBSTM32: STM32 FLASH OPTION BYTES PROGRAMMING describes the flash algorithm setup Option Bytes programming on STM32 devices. Refer also to the example in folder ..\ARM\Boards\Keil\MCBSTM32\Blinky. [ULINK Support] Corrected Fast GPIO display problem on NXP LPC2000 devices which was cased by a hardware side effect. [ULINK Support] Corrected a potential hang-up of ULINK2 when using the Serial Wire Viewer on Cortex-M3 devices. [ULINK Support] Added Flash algorithms which support off-chip Flash ROM devices on Cortex-M3 devices. The Cortex-M3 specific algorithm files use the file name extension *.FLM. [GNU Support] Enhanced support for GNU is now available for Cortex-M1/M3, ARM7 and ARM9 devices. Details are Application Note 199: Using μVision with CodeSourcery GNU ARM Toolchain.
