Hello, I'm using stm32f746 MCU with CMSIS-RTOS2, all working fine except: after wakeup from STANDBY Mode, MCU is not continue execute code, it start from main() reset. Which "Low-power mode" mode I must to use for continue code execution after wakeup?

stm32f746 Low-power mode
I have trouble to get working USB and bxCAN, device STM32F103RC (STM32CubeIDE v1.4), if bxCAN is not configured, USB work fine, together does not work - error "usb 1-1.3: device descriptor read/64, error -32". What I'm doing wrong?

By the way, it's not about HARD FAULT. The question is why does the controller reset when exiting POWER DOWN mode.

The HAL documentation is not good enough, unfortunately, but everything can be solved by experiments :)

I solved the problem using STOP mode: HAL_PWR_EnterSTOPMode (PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFE); Now MCU continue execute code from enter power down state.

I test it, USB work fine if bxCAN disabled.
