Ah, I think I see it now. We can't use 0x0 as where to load stuff to and the tests default to 0x0 if you don't provide an address rather than $loadaddr. I'll see about changing the tests. > > Second, the sleep command is not at all accurate.

I see the same failure for MIPS/PPC for the qemu targets we have as well. I don't see this under QEMU for the ARM targets that I'm emulating. I suspect there's some common problem on the U-Boot side as also don't see this on the VMs I have running under qemu nor when I boot the kernelci rootfs from U-Boot. -- Tom
