[Gumstix-users] Overo + Tobi Duo

[Fabian A. <xa...@ai...>]

Hi all!

I'm facing a strange problem with different revisions of the gumstix overo series. On our Tobi expansion board all three gumstix (2x R2498 and 1x R2499) are working without problems. Same thing with the old Tobi Duo boards (R2522). But now we recently got a new Tobi Duo board (R2742) which doesn't work as expected. Just one of the three gumstix boot successfully. Since I can't connect a console to the Tobi Duo I have no idea what's going on. The wifi module of the two gumstix which don't work also do not get hot as usual, that's why the problem has to be very early in the boot process (perhaps u-boot?). I also tried a recent image from sakoman (with u-boot) as you can see below (the other two gumstix still run a version from March).

Does anybody have an idea what could be going on here? 

Thanks in advance,
Fabian

P.S. I tried to summarize the firmware versions:
