Boot SPL from boot partition for a custom board using imx6ull

Hello all,

How to boot SPL from boot partition of emmc for my custom board using imx6ull?

When i flash my SPL to user partition using the below command, it boots as expected.

dd if=SPL of=/dev/mmcblk0 bs=1k seek=1 conv=sync

But doing the same with boot partition doesn't work. Can someone help?

Hi Brinda

one can try to select partition with "mmcdev" as described in i.MX Linux User’s Guide

Thanks for your prompt reply.

This guides talk about booting linux OS from emmc. I achieved that part already.

But i am stuck at booting SPL from emmc. I would like to use boot partition of emmc to store SPL & boot. But it works only with user partition.

The issue is resolved.

There was no problem with imx side. Changing the configuration register of emmc to enable boot partition resolved the issue.
