RE: [U-Boot-Users] Running test code from RAM while having GOT po inting to flash

Other possibility is the linker script. There is no method I can think of to know if this is correct (basically compare system.map vs u-boot.lds). It was derived from the mbx8xx board's u-boot.lds.
If you could double check it? I have a beta version of MontaVista toolchain which was compiled for PPC860. Otheriwse, it should work with 852T.
Thanks,

Please understand that the mode of failure you are observing makes this an extremely unlikely cause.
