Flashing updated uboot in Manjaro

[sciolus]

I stumbled upon this website: https://www.jwillikers.com/update-u-boot...nebook-pro

I followed the instructions.
With lsblk you can check which drive is your eMMC.
With Manjaro it's probably mmcblk2.

sudo dd if=/boot/idbloader.img of=/dev/mmcblk2 seek=64 conv=notrunc,fsync
sudo dd if=/boot/u-boot.itb of=/dev/mmcblk2 seek=16384 conv=notrunc,fsync

Not sure why the second command failed on your PBP.

My heart rate is coming back down to normal. I don't have anything critical on my PBP, but I don't have time to deal with bricking it.



I typed in the commands from the output of sudo pacman -Syu very carefully using mmcblk2.

Code:

A new U-Boot version needs to be flashed our install drive. Please use lsblk to determine your drive, before proceeding.
You can do this by running:
# dd if=/boot/idbloader.img of=/dev/mmcblkX seek=64 conv=notrunc
# dd if=/boot/uboot.img of=/dev/mmcblkX seek=16384 conv=notrunc
# dd if=/boot/trust.img of=/dev/mmcblkX seek=24576 conv=notrunc

I did not include conv=notrunc,fsync, just notrunc, as shown.



Rebooted fine.



I took it on faith to use blk2. I'm not sure how to know that with lsblk's output.

Code:
