Orange Pi 5 - bootloader / kernel update

Gladdle

I am sorry to ask stupid questions again, but i didn't understand the boot sequence for the Orange pi 5, also there are different bootloader.
I have watched a few youtube chanels, some tutorials. So what i know is that the Orange Pi 5 uses a Rockchip 3588. The developer got some "special" kernel builds, in my case it's a "5.10.110-3+" kernel - even there, not all the funtions (like USB or the NVMe) work propper. Thanks to Collabora there are drivers for the "Rockchip 3588" since the Version 6.3 in the official linux tree. So i try to update, install the gentoo-sources and genkernel. I got a new kernel (v6.6.7). The directory /boot/ contains this files:

Gladdle,

Do you have serial console setup for OPI5? I mean a usb to ttl serial cable from you other PC to OPI5?

Without it could be difficult to make change in u-boot.

I would not recommend you change u-boot or kernel if you are not familiar with embedded device would because there is quick a bit of stuff you need to know before you can run mainstream linux/u-boot.

See rockchip wiki about [url=]rockchip boot sequence[/url].

You may be able to make change in extlinux/extlinux.conf to switch kernel, however I doubt the new kernel you build will boot, It is possible that u-boot is currently programmed to expecting a u-boot specific format kernel image file in order for it to load.

BTW, in your previous post about USB not working, I have point out the button USB port of OPI5 is usb 2. so it is possible you used a incomparable cable therefor it is not working.

Hi. Don't want to create another thread, hope it's ok to continue this one as I've tried to do just that, boot mainline kernel on Orange Pi 5.

I started with a bootloader. From what NeddySeagoon said, there's more choice than just u-boot - but I chose u-boot. Do tell if it's easier with UEFI - or something else.

I wrote down what I did and how I failed hoping it'll help me understand what I did wrong.
It didn't. Hope youse can give a helping hand.

Preconditions:
- aarch64 crosscompiler set up

Hardware:
- Laptop x86_64, AMD
- SD card - I use 32GB class 10 SanDisk card
- USB-to-serial CH340
- Orange Pi 5

Procedure for creating Rockchip rk3588 u-boot image:

Create a directory for stuff:

Turns out I was missing kernel module for that adapter :oops:

I have progress!

I just put the kernel I built on the boot partition, will need to massage that orange a bit.

I get that now from the serial (that's a tail):

I have now flashed u-boot to SPI and it works.

Only my kernel still won't load:

Got the board to start booting kernel with extlinux and Image.gz

Now it fails booting kernel with:

It would seem I'm missing a clock driver.

Yet:

CONFIG_CLK_RK3588=y

Hmmm.

Tried with kernel 6.7.9 , same problem.

It works now.
Not sure what kernel bits I was missing, got kernel config from:
https://github.com/sarnold/arm64-mainline-linux/releases/tag/6.7.6-arm64-r2

compiled and kernel booted up! But no ethernet ...
Looks like PHY got stuck.

Used mii-tool and ethtool to reset it, rebooted and ethernet works ever since.
