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.
