PSDK3.9.0 FreeRTOS openocd调试问题

PSDK 3.9.0 stm32 arm-none-eabi-gcc

window下VScode使用cortex-debug插件调试

launch.json

{

"version": "0.2.0",

"configurations": [

{

"name": "Cortex Debug",

"cwd": "${workspaceFolder}",

"executable": "D:/STM32test/Payload-SDK-master/build/samples/sample_c/platform/rtos_freertos/stm32f4_discovery/project/armgcc/dji_sdk_demo_rtos.elf",

"request": "launch",

"type": "cortex-debug",

"configFiles": ["D:/STM32test/Payload-SDK-master/openocd.cfg"],

"runToEntryPoint": "main",

"servertype": "openocd",

"rtos": "FreeRTOS",

"showDevDebugOutput": "raw"

}

]

}

发现始终无法正常调试，main函数好像可以打断点，但在其他任务中打断点无反应，debug暂停时，终端报错uxTopUsedPriority未定义

把FreeRTOS-openocd.c文件放进PSDK一起编译后可才正常调试

FreeRTOS-openocd.c

* Since at least FreeRTOS V7.5.3 uxTopUsedPriority is no longer

* present in the kernel, so it has to be supplied by other means for

* OpenOCD's threads awareness.

* Add this file to your project, and, if you're using --gc-sections,

* ``--undefined=uxTopUsedPriority'' (or

* ``-Wl,--undefined=uxTopUsedPriority'' when using gcc for final

* linking) to your LDFLAGS; same with all the other symbols you need.

#include "FreeRTOS.h"

#ifdef __GNUC__

#define USED __attribute__((used))

#else

#define USED

#endif

const int USED uxTopUsedPriority = configMAX_PRIORITIES - 1;

看了下PSDK的RTOS版本：FreeRTOS Kernel V10.3.1，好像FreeRTOS Kernel V10.3.1发布的时候还没有解决这个问题
