STM32CubeIDE 移植 RT-ThreadNano问题总结

问题汇总

1. 用STM32CubeIDE新建工程时，用STM32CubeMX勾选了RTThread系统，但是生产的工程中没有MiddleWare。
   原因：因为更换过workspace,更换完成后配置Firmware and software package时选择到了D:\STM32Cube。
   解决：STM32CubeIDE系统设置问题，Firmware and software package必须要选到Respository文件层。
   
   同时勾选Do code generation on .ioc file save
   
   或者保存完.ioc文件后点击generate code
   
2. RT-ThreadNano 3.1.5版本可以按照上述方法解决，3.1.3版本仍然无法解决，一直没有middleware文件出现，

结论

目前仍然不能使用STM32CubeIDE+RTThread联调测试。问题是
编译时 libcpu/arm/cortex-m4/context_gcc.s (RT-Thread 启动文件）时出现如

/opt/gcc-arm-none-eabi-6-2017-q2-update/bin/arm-none-eabi-gcc -x assembler-with-cpp -c -mcpu=cortex-m4 -mthumb -mfpu=fpv4-sp-d16 -mfloat-abi=hard -DUSE_HAL_DRIVER -DSTM32F429xx -DHAVE_CCONFIG_H -DRT_USING_MINILIBC -DRT_USING_NEWLIB -Iboard -ICORE -IHALLIB/Inc -IHALLIB/Inc/Legacy -Ihardware/CAN -Ihardware/KEY -Ihardware/LCD -Ihardware/LED -Ihardware/SDRAM -Irt-thread/components/finsh -Irt-thread/include -Irt-thread/include/libc -ISYSTEM/delay -ISYSTEM/sys -ISYSTEM/usart -IUSER  -Og -Wall -fdata-sections -ffunction-sections -g -gdwarf-2 -MMD -MP -MF"build/context_gcc.d" rt-thread/libcpu/arm/cortex-m4/context_gcc.s -o build/context_gcc.o
rt-thread/libcpu/arm/cortex-m4/context_gcc.s: Assembler messages:

make: *** [Makefile:180：build/context_gcc.o] 错误 1

按照以下几种方式处理后仍然不能正常运行。暂时悬起，后面解决了再更新：

1. context_gcc.s:110: Error: thumb conditional instruction should be in IT block `vstmdbeq r1!,{d8-d15}
2. STM32cubeIDE F4移植RTT系统 context_gcc.s 报错
3. RT-Thread启动过程部分过程分析（GCC链接脚本部分内容）
