Forum Post: Unable to load U-boot for AM3351 processor

Good afternoon, I'm following the guide http://processors.wiki.ti.com/index.php/Sitara_Linux_Training:_uboot_linux_debug_with_ccsv5 but I'm not able to load the u-boot program after loading the SPL code. I'm able to load the SPL program and symbols and step through without any errors (to the best of my knowledge). As I'm using a custom AM3351 board, I needed to modify the DDR memory configuration and pinmux settings to be compatible with my board. The console output in my minicom windows is as follows U-Boot SPL 2016.05-00230-g120a8a3-dirty (Oct 15 2016 - 13:51:48) Timed out in wait_for_event: status=0000 Check if pads/pull-ups of bus 0 are properly configured Timed out in wait_for_event: status=0000 Check if pads/pull-ups of bus 0 are properly configured SPL: failed to boot from all boot devices ### ERROR ### Please RESET the board ### At this stage, according to the guide, I should pause the SPL code, and then load the u-boot program using Run -> Load -> Load Program. However, when doing so, I consistently see the error message File: .../u-boot: a data verification error occurred, file load failed. Could this be a problem with my SPL code? Or is there a problem with my u-boot file? Please let me know if you have any suggestions. Thanks for your support! Best regards, Chris
