OK so got my am437x-idk back up and running again. I'm kind of running out of space here.. And as suspected it won't boot with these changes. It's a UP core: CPU: ARMv7 Processor [412fc09a] revision 10 (ARMv7), cr=10c5387d CPU: PIPT / VIPT nonaliasing data cache, VIPT aliasing instruction cache OF: fdt: Machine model: TI AM437x Industrial Development Kit Regards, Tony
