[split] U-Boot with NVMe support, keyboard & display working

[as400]

New version of u-boot - 2020.10.

Kernel patch is still needed. I think the patch was accepted into mainline 5.10.

Good news - @simonsouth patch has made it into linux-5.9.2

So if your distro offers kernel 5.9.2 you can use this u-boot probably without the problems with display not initializing properly.

Thank you and others for your work in the community. I'm very new to Linux and reading through this thread makes me interested to try out. I like the idea of choosing what device to boot from. My pinebook is running manjaro 20.10 and I believe the uboot from factory resides in the Emmc and would like to replace the current one with that in this thread. Though honestly I don't know where to start, would someone be kind enough to explain how to implement this?

@FeMike, First, try learning more about your existing system. Dealing with U-Boot is very experimental, and has the potential to soft-brick your Pinebook Pro.

If you are really new to Linux, you need to check the kernel level with the following command. Then you can see if your kernel is at 5.9.2 or higher.

Code:

uname -r

I've been working with Unix for more than 25 years, and still get bit by odd things. It's never fun to spend hours trying to recover from some bonehead mistake, That of course you did not know was a bonehead mistake, until after.

Nice, yeah it's running 5.9.6.1

Edit: So I just went for it and just did it. I learned a few things and it seemed to work though I may not fully understand how to choose which device to boot from. I press control+c for boot menu but it continues on to boot from sd card. I'm sure I'm missing something but when I get back from work I'll keep trying. Thank you.

I have the same problem, but oddly enough if I hit the arrow keys instead of ctrl+c on boot, it works every time.

Nice guys You just discovered and "undocumented" feature

I have uploaded new u-boot version 2021.01.

I have removed opinionated boot menu where you select device to boot from. So if you are really attached to it - DO NOT UPGRADE.

It still has extlinux.conf based menu where you can select system/kernel to boot.

I assume this new upload still doesn't work with deep sleep, unlike MrFixit's v2.0 release from https://github.com/mrfixit2001/updates_r...filesystem?
