Low-level error "while(__HAL_RCC_GET_FLAG(RCC_FLAG_HSIRDY) == RESET)" infinite loop [Copy link]

STM32 uses an internal oscillator. When debugging the code that used to work, I found that it always died in the HAL_RCC_OscConfig function of the stm32f0xx_hal_rcc.c file. The following code was repeatedly executed

1. /* Wait till HSI is ready */ while(__HAL_RCC_GET_FLAG(RCC_FLAG_HSIRDY) == RESET) { if((HAL_GetTick() - tickstart ) > HSI_TIMEOUT_VALUE) { return HAL_TIMEOUT; } }

Using STM32CubeMX to change the main frequency, regenerate the code, and change the board did not solve the problem. Later, I wanted to try whether it was a problem with jlink. I found a nucleo development board with a built-in simulator, connected the st-link lead to the board to be tested, and when I was about to change jlink to st-link in the IAR project settings, I found that the simulator was selected under Simulator! ! !

I also encountered this problem. After reading your post, I solved it. Thanks

Compared with MDK, IAR does not do well in many areas and does not achieve what you see is what you get.
