Boot issue in STM32MP257F-DK board

Hello Experts, 
I am using  STM32MP257F-DK board and trying to bring up the board with starter package. 

I followed the steps as mentioned in this link - https://wiki.st.com/stm32mpu/wiki/STM32MP25_Discovery_kits_-_Starter_Package

The starter package that I have downloaded and flashed - en.FLASH-stm32mp2-openstlinux-6.6-yocto-scarthgap-mpu-v24.11.06.tar.gz

I was able to flash the SD card successfully as mentioned in section 6.

(Note that I have taken care of boot switches accordingly)

However, when I restart the board for booting, seems there are issues and does not stop at login prompt. Instead stops or boots in loop. Attaching 2 logs with 2 instances of reset. Kindly help to review and suggest work around if  have missed any steps.

It sounds like your STM32MP257F-DK board is stuck in a boot loop after flashing the starter package. This could be due to a corrupted SD card image, power instability, or a missing boot component.

Here are a few things you can try:

  1. Reflash the SD card using a verified tool like Balena Etcher.

  2. Double-check boot switches and ensure they match the boot-from-SD configuration.

  3. Use a reliable power source, as power dips can cause boot loops.

  4. Connect via UART serial to monitor the full boot log—it can reveal where it’s failing.

If you're working on embedded systems for a moving company (e.g., for GPS tracking, sensors, or logistics control), resolving this boot issue quickly is key to keeping your systems running smoothly.
