Hello imx7 developers,
I have an i.mx7ulp evk board and have been chasing an issue that prevents me
from using my own u-boot image flashed to the SD card to boot the board. The
basic steps I followed are
1. build u-boot image using mx7ulp_evk_defconfig and I get u-boot-dtb.imx. I am
using NXP's 5.4.x GA release. But would like to use the latest from upstream
tree as well. So your response can be based on upstream version.
2. SD card formatting. create 2 partitions using fdisk command. u-boot image is
at the start of partition 1 as per available information. So partition 1 starts
with first section at 20480 and last at 1024000. Partition 2 at 1228800.
3. For now I just want to boot with u-boot only and not to Linux. So I program
u-boot image using dd command as
sudo dd if=u-boot-dtb.imx of=/dev/sde1 bs=1k seek=1 conv=fsync
where u-boot-dtb.imx is my u-boot image from step 1. /dev/sde1 is device
for the first partition
>sudo dd if=u-boot-dtb.imx of=/dev/sde1 bs=1k seek=1 conv=fsync
[sudo] password for sandc:

sandc@sandc-VirtualBox:~/git/uboot-imx (imx_v2020.04_5.4.70_2.3.0)$ sync
4. Eject the sd card and boot i.mx7ulp evk with this SD card.
Unfortunately the console shows the old image
U-Boot 2020.04-5.4.47-2.2.0+gffc3fbe7e5 (Sep 11 2020 - 19:56:06 +0000)
Have anyone seen similar issue and have clue on what is going on. Thanks for
your feedback.
Thanks
Murali Karicheri
