I build a uC/OS project with keil5.12 , and my cpu is stm32f429zi serial .I am using STMicroelectronics STM32F429Discovery board . when i want to DEBUG , keil also become no response , but i can download to the board by j-link . The program can run correctly on board, but i want to DEBUG.what should i do to avoid this situation , If necessary i can provide the project.Please help me!!!
Does your idle task use WFI ?
Make sure the part does not enter a low power mode, check DBGMCU peripheral settings.
when i downgrade keil5.12 to keil5.11 , the program can DEBUG on that Version . And my task is only to Toggle two leds with delay some time . I cant use WFI mode , if this is a bug on keil5.12 and I can provide the project .
