Have you put the som in SD boot mode (SW1 set to 11) and tried placing
your boot.bin image there? I'm not sure if there is a valid route for
the som to use off board flash unless you create a custom hardware
project and use the associated fsbl that you'd need to make. But even
then I don't think there is a path from the PS to flash that would be
on your FMC card as I don't think the som maps any ps stuff to the
FMC. Curious how you make out as I'm interested in eventually running
linux on the picozed.
