Hi Wolfgang, vxWorks needs all interrupt to be disabled before it's boot up, while u-boot sometimes enables them. Recently, I'm facing this kind of problem about booting up vxWorks through bootvx command. So, I added a patch to the common/cmd_elf.c to disable all interrupts before run into vxWorks image. This patch is now working fine on my board. So I think maybe it will be helpful for others. The following is my patch : commit 66768801bb10477ca8431b284d1738dcf3a834b8 Author: Ke Pan <pppeterpppan@gmail.com> Date: Wed Oct 12 09:50:44 2011 +0800 common/cmd_elf : Disable interrupts before boot vxWorks The vxWorks needs all interrupts to be disabled before its boot.
