X-Nucleo-IDB05A1 boards problem

[BSalt.1]

I have a few X-Nucleo-IDB05A1 boards, and when I test them on the X-Cube64 board, some work and some don't. So I checked it, and like the attached picture file, the Trace Code and Bulk ID are different.

Trace code XN915011 is fine,

11540270 doesn't work at all.

What's the matter?

HI @BSalt.1​ ,

Do you confirm Jumper and solder bridges configuration are exactly similar on both boards ?

Thanks,

Sebastien.

Hi,

Yes the idb05A1 board has only one 2pin jumper block and some 0 ohm jumpers that need to be replaced by soldering, both types of boards are factory-set.

Thanks,

Ewing.
