Nucleo-F756zg: Debug support for StopMode does not work #91

Closed KamilDuljas closed 1 year ago

KamilDuljas commented 1 year ago

Hi, I try to run PWR_CurrentConsumption example on Nucleo-756zg. All works fine without debug, but i tried use each mode in debug mode. Sleep mode and StandBy mode work fine with debug but StopMode not.

When we try to enter to stop mode and will be executed _WFI() then immidately exit from the mode during debug session. I tried perform this through: STM32CubeIde 1.12 and STM32CubeProgrammer

The only one modification against to original exmaple is keep PA13 PA14 PA15 as there are pins connected to stlink. https://github.com/STMicroelectronics/STM32CubeF7/blob/6a3b9bb8d09839f365ba83a6cf5823ae5f5226db/Projects/STM32F746ZG-Nucleo/Examples/PWR/PWR_CurrentConsumption/Src/stm32f7xx_lp_modes.c#L91


GPIO_InitStruct.Pin = GPIO_PIN_All & ~(GPIO_PIN_13 | GPIO_PIN_14 | GPIO_PIN_15);

All usecases executed using multimeter.
