Watchdog issue when booting Uboot(V2025.04)

[Aks]

Dear Team,

We are trying boot Uboot(V2025.04) on a Custom board with STM32MP157AAA3 Processor.But while booting we can see that code hangs at WDT: started Watchdog@5a002000 with servicing every 1000ms (32s timeout) and restart after sometime.We have attached the screenshot for the reference

 

Thanks & Regards

Hi @Aks 

According to Release notes this version of uBoot is not supported.

Hi @PatrickF 

Sorry for the delay in the response.

You mentioned that the updated version in use is U-Boot v2023.10-stm32mp-r2.
However, we observed that U-Boot v2025.04 boots successfully on the STM32MP157D-DK board.

On our custom board using STM32MP157AAA3, the boot stops after printing:

“WDT: started Watchdog@5a002000 with servicing every 1000ms (32s timeout)”

The system then restarts after the watchdog timeout.

So watchdog is correctly started, and the crash occurs after (and the watchdog reset the board after 32s)

No clue what occurs next of this. Maybe you could enable more log.
