u-boot for Arch Linux Arm - prw - 07-19-2019
Hi all,
I've put together a PKGBUILD for building u-boot for the rockpro64.
I have some instructions and the uboot binary and boot.scr here:
https://github.com/prw/PKGBUILDs/releases/tag/uboot_testing
The mainline linux-aarch64 kernel is functional but is definitely not optimal for this board.
The kernel is quite slow to boot and takes 3-5 minutes.
U-boot is based on ayufan's linux-u-boot.
I hope someone finds this useful.

Thats great as a big fan of Arch and will be having a look at how you did PKGBUILD.
Manjaro in a way have pipped you to the post though as

The minimal version has sort of already been done for us

Ahhh, I did not know about the manjaro port when I started working on this. Thanks for pointing this out.
Unfortunately I believe they have built their uboot incorrectly.
The board can easily be crashed by reading 3-4GB of data.
I can crash the manjaro image by running: dd if=/dev/mmcblk0 of=/dev/null bs=1M
It crashes after reading ~3.4GB.
uboot is not correctly initializing the memory controller properly and the kernel crashes once enough cache is used.

Uboot is pure mainline as far as I know

Go tell the devs as they will be happy for the info.
