Hi All: I run a test in app_main, it shows: A stack overflow in task main has been detected. so I want to change the main stack size , and I searched in menuconfig but nothing found, only a pthread stack size can be set. Is this the right one?Activity...
does anyone know why the return value of `uxTaskGetStackHighWaterMark()` for main task can be higher than the "Main task stack size" set in sdkconfig?In my `sdkconfig`: Common ESP-related -> Main task stack size: 20000Here is my `main.c`: ...

第一步:操作CP15协处理器TPIDRPRW寄存器,它被ARM设计保存当前运行线程的ID值,在ARMv7架构中才新出现,需PL1权限以上才能访问,而硬件不会从内部去改变它的值,也就是说这是一个直接暴露给工程师操作维护的一个寄存器,在鸿蒙内核中被用于记录线程结构体的开始地址,可以搜索OsCurrTaskSet来跟踪哪些地方会切换当前任务以...
