[U-Boot] [PATCH 0/1] i.MX8QM ROM 7720 a1 board won't boot

[Oliver Graute]

I'am currently working on the following patch to get the imx8qm-rom7720-a1
board working with recent u-boot v2019.07. Unfortunaly I get no output on my
serial line.

I'am not sure if something in my patch is just missing or if my composition of
"SCFW + ATF + uboot" which is necessary for this imx8qm board, is not working
the right way.

Perhaps somebody can guide me in the right direction to debug this further.

Currently I'am applying the patch and building u-boot this way:

$ export ATF_LOAD_ADDR=0x80000000
$ export BL33_LOAD_ADDR=0x80020000
$ make imx8qm_rom7720_a1_4G_defconfig
$ make flash.bin
$ dd if=u-boot.itb of=flash.bin bs=512 seek=854
$ sudo dd if=flash.bin of=/dev/sd[x] bs=1k seek=32 conv=fsync

Then I put the SD card into the board and power it on. But no output ony my
serial line.

Best Regards,
