Odroid M2 - how to boot this board?

[nmset]

Hello,

I'm requesting help to get ARCH running on the Odroid M2 board.

The device works well with the stock Ubuntu distribution which is not my preferred one.

I have done the following steps:

1. Deactivate booting from eMMC by simply moving the files in the boot partition to a backup directory after mounting it as a USB mass storage.

2. Copy the first 3 MB of the boot partition to an SD card, making it bootable with the SPL and uboot.

3. Create a boot partition and a root partition on the SD card.

4. Copy the Image kernel and initramfs-linux.image files from Arch's linux-aaarch64 package, version 6.12.1-2-aarch64-ARCH, on the boot partition.

5. Copy an rk3588s-odroid-m2.dtb file on the boot partition, than can come from 2 sources.

6. Create a boot.scr file as below.

setenv bootargs "${bootargs} console=tty1 console=ttyS2,1500000 root=LABEL=SDROOT rw rootwait=5 pci=nomsi net.ifnames=0"

setenv fdtfile "/rk3588s-odroid-m2.dtb"

if test -n "${console}"; then
setenv bootargs "${bootargs} console=${console}"
fi

if test -n "${default_console}"; then
setenv bootargs "${bootargs} console=${default_console}"
fi

if load ${devtype} ${devnum}:${bootpart} ${kernel_addr_r} /Image; then
if load ${devtype} ${devnum}:${bootpart} ${fdt_addr_r} ${fdtfile}; then
if load ${devtype} ${devnum}:${bootpart} ${ramdisk_addr_r} /initramfs-linux.img; then
booti ${kernel_addr_r} ${ramdisk_addr_r}:${filesize} ${fdt_addr_r};
else
booti ${kernel_addr_r} - ${fdt_addr_r};
fi;
fi;

The result is always bad.

If rk3588s-odroid-m2.dtb comes from linux-aarch64-6.12.1-2 package, the screen never lights up and multiple lights blink on the board.

If rk3588s-odroid-m2.dtb comes from Ubuntu, the screen lights up with a bar at the top, then becomes black after about 15s, and lights stop blinking on the board.

Multiple trial-and-error configurations of boot.scr, file layout and more did not help.

I'm requesting help from people more knowledgeable here, the uboot thing is quite foreign to me.

Thank you for any input.

Using the 6.12.1-2-aarch64-ARCH kernel, its initramfs and its FDT file, the board boots but with a black screen.

Typing blindly 'root/root' to login, then 'systemctl poweroff', it does shutdown.

So there is a running system, with a flashing blue light and a flashing orange ethernet light. The device is not visible on the LAN unfortunately.

[nmset]

There is progress with 6.13.0-rc3-1-aarch64-rc-ARCH and its FDT file.

The screen gets backlight at the very last moment, showing the login prompt fully functional. Boot messages are not printed before.

But network connection fails on the ethernet port, with a blinking orange light. It does work with Ubuntu. There is no IPv4 set at all and no route. An IPv6 link local address is always set, with a default route on that address. After a few minutes, a routable IPv6 address appears, but the default route is not updated and any pîng fails. Setting a default route to the IPv6 gateway does not help.

Moreover, the MAC address changes on every boot. It can be set to a fixed address in the boot.scr file with 'setenv ethaddr <address>'. With Ubuntu, the MAC address does not change on every boot, without the setenv instruction.

Finally, using an USB ethernet adapter allows a network IPv4 and IPv6 connection to be established seamlessly on boot. Another ethernet USB adapter combining an USB hub failed to work.

All this with systemd-networkd and DHCP. netctl did not help.

The board is not reliably usable at this stage.

In the hope that some Arch developers might consider.

Here is some information from inside:

HDMI support for the rk3588 in the mainline kernel only got merged in 6.13. So it makes sense you had to use the rc kernel to get output.

Regarding the built-in networking, have you tried running dhcpcd directly on the interface? Regarding using systemd-networkd, what system.network files do you have configured in /etc/systemd/network? Do you have an .network that will against "end0"?

[nmset]

Thank you for your reply @hyke.

I tested multiple simple configurations with systemd-networkd and with dhcpcd. Addresses and routes are set on static configs but not one single bit goes through the NIC. DNS entries are rightly set in /etc/resolv.conf.

The following posts show the tested configs.

After reading many internet sources, I resolved to poke in HardKernel's code, replaced 2 functions in the dts file of the Linux source tree (v6.13-rc6) and built the FDT file (make dtbs). The result is a functional ethernet port, simply working. Let's hope mainline ships a working FDT file soon by any means and by any code.
