Flashing updated uboot in Manjaro - TDC_PBP - 02-07-2020
Does anyone have clear, specific instructions on how to install the updated uboot in manjaro? I tried to follow these instructions in the /boot file in manjaro:
flash_uboot() {
echo "A new U-Boot version needs to be flashed onto your install drive. Please use lsblk to determine your drive, before proceeding."
echo "You can do this by running:"
echo "# dd if=/boot/idbloader.img of=/dev/mmcblkX seek=64 conv=notrunc"
echo "# dd if=/boot/u-boot.itb of=/dev/mmcblkX seek=16384 conv=notrunc"
}
## arg 1: the new package version
post_install() {
flash_uboot
}
## arg 1: the new package version
## arg 2: the old package version
post_upgrade() {
flash_uboot
}
but....the second dd command failed (never gave any visible output) and I temporarily bricked my PBP
. I don't particularly want to repeat that experience EVER again, so I don't want to try it again until someone else gives it a good look over. Confusingly, I found these instructions printed in the terminal while doing pacman -Syyu:(213/215) upgrading uboot-pinebookpro [############################] 100%
warning: /boot/boot.scr installed as /boot/boot.scr.pacnew
warning: /boot/boot.txt installed as /boot/boot.txt.pacnew
A new U-Boot version needs to be flashed onto /dev/mmcblkX.
You can do this later 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
(214/215) upgrading xorg-server-common
Thoughts/ideas??
P.S. I am running Manjaro from my emmc and did check to make sure I flashed the correct drive (the emmc)
RE: Flashing updated uboot in Manjaro - slyecho - 02-12-2020
I managed to mess up one install on the SD card by following the instructions in pacman. When I got a new image working again I copied it all to eMMC and it is working fine now and I haven't touched the uboot again.
There is some discussion in the Manjaro ARM forums about this: https://forum.manjaro.org/t/uboot-img-does-not-exist-in-boot/120019
My suggestion is to leave it alone if it is working (that is boot from eMMC and SD card etc).

I stumbled upon this website: https://www.jwillikers.com/update-u-boot-on-the-pinebook-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.

Correct, op is flashing to mmcblkX. Which is likely supposed to me mmcblk2. They should probably mention that in the instructions which say to use lsblk.

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=notruncI 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:

Nearly always,, the controller on emmc partitions part of the NAND
to boot0, boot1, rpmb
This NEVER happens on uSD or SD chips
I do have 1 very recent emmc without boot0 etc, this is rare
BTW, rk3399 or rk3328 (cpus) do NOT use boot0 or boot1
