How to check u-boot.imx is downloaded properly?

[hishamelmeligi]

I have a custom board using imx6D, I am using the serial down-loader mode to download the u-boot.imx file and it was jumping to the u-boot properly; the u-boot console window is not shown.

Now the SoC after I download the u-boot.imx,doesn't jump to u-boot and the console is not running although the imx_usb status is ok.

Please note that the last time the board was working, I downloaded the u-boot.imx using sb_loader.

I am thinking the problem may be either in the RAM or the boot rom code.

Please I need advice how to proceed with debugging.

Hi Hisham

one can look at suggestions given on

i.MX6Q NAND boot issues 

attach the board with any JTAG debugger and dump 0x907400 (ROM

uses 0x907000 as starting address), one should see IVT header here.

Best regards
igor
