Hi All:
Did anybody use u-boot to load vxWorks? I have sequoia board (NOR flash) and when I tried simply boot vxWorks elf, it hangs.
vxWorks native bootrom.bin works fine, booting the very same vxWorks elf perfectly.
Please take a look at "[PATCH] Make Sequoia boot vxWorks" posted on Juli 30. Problem areas are two different chip selects and different TLB settings, which collide (u-Boot needs TLB#0 for the boot flash and vxWorks needs TLB#0 for its exception handling).
I have a custom PPC440EPx work where I have to make vxWorks work on it, which is a real pain. If you are interested to share insight you may also contact me directly.
