booting problem with U-boot on iMX6Q processor on custom board

jaymind — Fri, 17 Oct 2014 14:18:52 GMT

Hello all,

I have custom board name as 'camaro' with iMX6 Quad processor.
I faced a problem when I update my u-boot from mmc,

I apply 'run upgrade_uboot' into uboot prompt

then after I didn't get any prompt to run the next command...

then I restarted my board but I didn't get any prompt.

I included some outputs below

I'm not really sure what the problem could be.

-----------------------------------------------

U-Boot 2013.07 (Jul 24 2014 - 14:51:00)

CPU: Freescale i.MX6Q rev1.2 at 792 MHz

Reset cause: POR

Board: MX6Q-Camaro

DRAM: 1 GiB

MMC:

somehow is there any possibilities to restore or reset u-boot into its default state ?

thanks in advance....

Hi Jaymin

probably "upgrade.." is not implemented in that uboot.

One can try to write sd with sudo dd.. as below

Task #4 - Deploy and test

Best regards

Hello,

Sorry for late...

Thanks a lot for reply,

actually I tried as per your suggestion and also use new one SD card and boot up board but its not worked.

Board only detected serial flash (SF) after power ON and stop the prompt at that point.

So, Is there any other way to create SD card or directly flash u-boot into processor ??

And one more thing that I also tried to made SD card contain only u-boot.imx and made it by DD command as link suggested by you in reply.

So suggest any new way to bring up that custom board.

Waiting for your suggestion......

Reply soon,

Thank You.

Regards
