Right, which is why I'm wondering why are there sevral new AM33x mach-types when only one of them is being used: 3684 TI AM335X IA EVM am335xiaevm Afzal Mohammed 3589 TI AM335X EVM am335xevm Vaibhav Bedia 3808 Beaglebone Board beaglebone Steven Kipisz Russell has been trying to cleanup athe mach-types, so if these others are not going to be used, I suggest they be deleted. > But I am surprised to see that beaglebone is booting fine for you, > did you get Linux console? Oh, sorry for the confusion. No, it didn't boot to console. It just booted far enought to see that your this series was working and it was getting started, but it eventually hangs because of missing MPU hwmod: [...] [ 0.000000] omap_hwmod: timer1: cannot setup_one: MPU initiator hwmod mpu not yet registered [ 0.000000] ------------[ cut here ]------------ [ 0.000000] kernel BUG at /work/kernel/omap/dev/arch/arm/mach-omap2/timer.c: 214!
