I do also experience the boot problem described by Geert. Head being: b0625afe305253d0831af9289b37c906c18a781b ARM: OMAP2+: Drop legacy platform data for am3 mpuss => BBB boots Ok. Head being: 5a230524f87926f24d637fe62fd689f7f86f5036 ARM: dts: Use simple-pm-bus for genpd for am3 l4_wkup => BBB boot fails. (I don't have any debug parameters => last thing I see in UART is from uBoot:
Looking at the .config Geert sent me, at least CONFIG_SIMPLE_PM_BUS=y is now needed, and probably should be selected or default y for omaps. Adding that removes the -512 errors at least that I started seeing with Geert's config too. Can you guys check if adding CONFIG_SIMPLE_PM_BUS=y fixes the problem? Regards, Tony
