HI.
I have a custom board that basically identical to the PDK
We Made 2 Boards for test.
One starts up OK
The Other fails
Section of Console below
The section of interest is the line
INFO: CPU 0 IT Watchdog 2 and so
The Same SDCard in both.
Must be a hardware issue but what?
Any Help appreciated

Hi @Bkell.1 ,
If the two custom boards are identical and that you are using the same SD Card for both, you are right it looks like an hardware issue.
Please can you enable the debug traces of U-boot for all the files that can be interesting (especially in those where the behavior is different) : https://wiki.st.com/stm32mpu/wiki/U-Boot_-_How_to_debug
Then please provide us the complete logs of the two boards (the one that works and the other). We will look at them.
