I wasn't sure if this is a Linux issue or a u-boot issue.
We are using an older version of arch/ppc MontaVista Linux and having a problem with u-boot. We can build a zImage and convert it to a uImage and it runs from u-boot fine.
If we build a uImage from MV, the kernel crashes as shown below. We are using u-boot version U-Boot 1.3.0-rc3.
Yet we can boot an arch/ppc Linux kernel (uImage) that's based on 2.6.26. Is there something we're not realizing that is different in the u-boot interface?
Thanks, John
