Informations about boot-chain: http://opensource.rock-chips.com/wiki_Boot_option
my board had a broken bootchain on emmc which prevents bootup from sdcard. Board can be booted up when pressing switch labeled “MASKROOM” while poweron. This shortcuts emmc and so skip this. Mostly emmc is not available from uboot, so i needed to boot linux kernel (which does emmc init again). There it was possible to erase beginning of emmc user-partition (mmcblk1).
dd if=/dev/zero of=/dev/mmcblk1 bs=1M count=10
erasing the first 2M was not enough (should delete the idbloader at block 64)…
Currently only binaries, no source

There is a merge-request for basic support (bl31 without scmi and no ddr init):

I have merged v11 to my repo here (only compilation tested yet):

My own work:

R2pro is supported only till 2022-04 as 2022-07 contains Patches that break atf inclusion
2023-04 got patches to support r2ro again: https://github.com/frank-w/u-boot/tree/2023-04-bpi
default boot way is via BPI-BOOT/extlinux/extlinux.conf

This is about to be changed with this u-boot patch series: https://patchwork.ozlabs.org/project/uboot/patch/20230409084454.v9.8.I4cf7708a1ba953b9abd81375d93af34665c7b251@changeid/
So i'm adding fit booting and builtin env like for r64 and r3 for 2023.07+
BPI-R2PRO> ls $device $partition BPI-R2PRO> setenv fit bpi-r2pro-netnext.itb BPI-R2PRO> run buildargs BPI-R2PRO> fatload $device $partition $loadaddr $fit 10845897 bytes read in 937 ms (11 MiB/s) BPI-R2PRO> bootm $loadaddr
R2pro will be supprted as own board in uboot 2024.01.
Pcie is usable too,but needs manual enabling regulators
https://www.mail-archive.com/u-boot@lists.denx.de/msg488399.html
run buildargs tftp $loadaddr 192.168.0.10:6.6-main-bpi-r2pro.itb bootm $loadaddr
alternative to uboot as bootloader, supports ethernet/tftp-boot (wan-port only due to missing switch driver)

Current way is spl-uboot in idblock.bin loading full uboot (fip,uboot.img) on separate partition (p1).
partition-layout from peter geis:
https://gitlab.com/pgwipeout/quartz64_ci/-/blob/main/.gitlab-ci.yml#L103
i use version from manjaro in my build.sh
This way works with downstream (2017.x) and upstream (2021.10+) uboot. Barebox does not need uboot partition,but for compatibility reasons partition should be there.

Further trees (like 5.17-r2pro*) will not contain the full phy driver,only my reduced version and dsa.
vop2 driver (needed for HDMI)
V5 seems to work good for 720p, 1080p and 4k

Have hdmi output, hdmi audio, gpu works with peters defconfig.
needs actual userspace (e.g. ubuntu 21.10) and ppa: https://launchpad.net/~kisak/+archive/ubuntu/kisak-mesa
