This is a great idea! So first I loaded the unmodified barebox binary using: mmc rescan 0 fatload mmc 0 0x82000000 barebox.bin go 0x82000000 It started executing and the error was the same as before. Then I tried doing what you suggested above and commented arch_init_lowlevel in ./arch/arm/mach-omap/omap3_core.S and I was not sure what you meant by `pin_mux` as the string appeared nowhere in the code but I thought you might mean the mux_config in ./arch/arm/boards/omap/board-beagle.c ? But after doing that, barebox would just not start anymore when loaded by uboot. So can you give me some more specific advices on what to comment? > Another thing: Where does this string come from?

Initially I only got the message "Cannot reset the SD/MMC interface" from line 1185 in ./drivers/mci/mci-core.c after it tried to call the init code from omap_hsmmc.c. But where would you find "timeout waiting for reset done"? I tried to recursively grep my barebox sources without finding this string? thanks! cheers, josch _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
