Flash U-Boot - stefan.schumacher - 03-21-2020
Hi,
I just booted the Manjaro eMMC installer from SD and flashed my eMMC storage. Everything works as it is supposed to be. I have a running system I can log into.
My first step was to run pacman -Suy. It prints some lines concerning u-boot, which wants me to flash files to my install drive.Is my install drive the eMMC or the block devices called mmcblkboot0 and mmcblkboot1? I have already flashed mmcblkboot0 but I am unsure if this is the right place and decided to ask here before rebooting and having to reflash a bricked device.
Where do I put idbloader.img and i-boot.itb go on the pinebook pro? What is supposed to be on mmcblkboot0 and mmcblkboot1?
Yours
Stefan

raw, starts at sector 64

in mmcblk1boot0 probably, starts at sector 16384 (8M)
mmcblk1boot1 likely empty
ATF starts at 12M, hasn't changed

Just to be sure that I understood you correctly: Both of these images have to be flashed to boot0 and boot1 does not fulfill any function when using u-boot, correct?

NO, definitely not for idbloader,, STARTS at sector 64
Its really hard to tell where boot0 and boot1 are located,
don't show up in fdisk or cfdisk or gparted
So, you tell me
uboot STARTS at sector 16384, do the calculations, that is 8M
I think the location for idbloader is baked into chip,
where uboot is located is a config in idbloader,
in other arm devices uboot is in a different location
Oh, and BTW, I am still on the uboot from MJ19.12,
since everything works well, especially sleep
IOW, there is no problem needing fixing, why risk mucking it up
