1. 更改默认环境变量 使用scons编译时，RTT_CC环境变量用于标识编译时使用的工具链，默认配置使用gcc，如果需要修改为iar，则可以编辑文件env_released_1.2.0\env\tools\ConEmu\ConEmu\CmdInit.cmd，找到set RTT_CC=gcc项，将gcc改为iar即可 2. 为STM32F733移植rtconfig.py，支持GCC/IAR/KEIL编译，支持硬件浮点，注意STM32F733的FPU为fpv5-sp-d16，详细可参考链接 https://www.keil.com/support/docs/3716.htm https://www.keil.com/support/man/docs/ARMCC/ARMCC_chr1359124920656.htm https://developer.arm.com/documentation/dui0472/k/Compiler-Coding-Practices/Processors-and-their-implicit-Floating-Point-Units--FPUs- --------------------------------------------------------------------------------------------------------------- import os #
