Hi Colin,
Did you write your conf. from scratch? What's your cpu_reset_needs_v4_MMU_disable value?
Thanks,
Bear.

Subject: OMAP cannot reboot
Hi there,
My OMAP porting works well right now, but it still has a little problem on reboot.
When reboot command is executed, CPU will hold.
After I traced every assemble line, I found that it halts in this command of cpu_reset() in locore.S.
mcr 15, 0, r0, c1, c0, 0
Could somebody please give me some hints?
Thanks and regards,
Colin
