Issue updating U-Boot to the microSD card

GoogleGroups
#1

Hello,

I am trying to boot up my custom board by bypassing the board ID check.

Therefore, I am following this guide to update u-boot and install it on a microSD card that has Debian Stretch IoT 9.4.
All the steps till step 6 worked fine. So, I was able to build the new u-boot. The lsblk command showed that my memory card is called ‘sdd’.

After typing:

$ export DISK=/dev/sdd
$ sudo dd if=./u-boot/MLO of=${DISK} count=1 seek=1 bs=128k

This showed up:
dd: failed to open ‘./u-boot/MLO’: Not a directory

Any ideas how to solve this issue?

Yeah, I’d start by looking at the screen… is MLO in a directory called u-boot?

Regards,

Sorry, I forgot to mention the link to the guide from Octavo Systems forums.

Yes, I have both MLO and u-boot.img on my Ubuntu machine after compiling u-boot:
