Greetings,
I'm porting a custom platform based on mx28evk to latest U-Boot.
I modified the iomux.c for my platform (different DUART pins) and made some changes to
mxs_adjust_memory_params() to accommodate to my DRAM chip.
I built the u-boot.sb. The platform however does not boot either from USB or
from MMC.
When loaded through USB, sb_loader complains with the messages at [1].
I fear the CPU resets before even executing the SPL code, but how could I tell? Is
there a way to check if the CPU reaches this code at all?
I don't see any ROM error codes either and the CPU seems to reset (when the USB
recovery mode fails, the target defaults to boot from flash my old v2009 U-Boot).
Is there any other init stuff (linker scripts or something) I should take care of
that's preventing sb_loader to fully load the image?
Thank you.
[1] sb_loader output
'Freescale,Inc.' 'ROM Recovery' device at USB path 0002:0034:00
