When I loaded the uSD into my Tritium-H5 all I got was just the red power light, but no activity. Tried a few different power supplies with the same result. I finally figured out that it appeared the bootloader was missing. I used Libre Tech's flash tool to flash their bootloader to my uSD card. Now I was able to get the Tritium-H5 outputting the boot sequesnce on the serial console. However, it stops at:

I stumbled through the u-Boot recovery process and after remounting the partition r/w I got dpkg to install 

linux-u-boot-tritium-h5-current_25.5.1_arm64__2024.01-S866c-P42f9-Hc721-V3ed7-Bb703-R448a.deb

However, when I rebooted the Tritium-H5 I was still stuck on the above spoiler. 👆  Am I doing something wrong? How can I get the Tritium-H5 to boot the Armbian image? Thanks!

I tried following the instructions here, and using a .dtbo file (hifiberry-amp100.dtbo) I copied from OSMC I have here on an RPi 3, but I don't think that's right as it mentions 'brcm,bcm2835' which I suppose means it can only be used with RPi.

The above mentioned .dtbo file seemed to be in some binary format, although I could still make out some text in it.  I can't even seem to find the uncompressed (plain text) versions, I searched OSMC and HiFiBerry repos (amongst others), I don't think I am looking in right place (maybe I need to look in RPi Foundation or Linux kernel sources?).

Any help or pointers will be appreciated.  This seems to be a non-trivial task (at least for a low to medium level wizard such as myself).

I have three Libre Computer Tritium H5 boards and three eMMC modules on hands. All three eMMC modules is flashed with exactly same Armbian image and exactly same uboot. I also use exactly same PSU and cable for all three boards (however I reproduced this issue with four PSU and three microUSB cables, no difference in behavior was found).

1. All three boards start just fine from microSD (so it's not exactly "Your board doesn't work?" case).
2. One board never boot from eMMC on first power up, but almost always boot on second power up. That reproducible with all three eMMC modules.
3. Two other boards just never boot from any eMMC module.

When board can not boot from eMMC it just stuck there:

DRAM: 2048 MiB

That five power up attempt as you can see.

I tried to rollback uboot to 2020.04, but it behave in exactly same way.`

All three boards was ordered at the same time, in one package.

Is anyone can reproduce this?

Is there anything else to try, or I should just give up and stick with microSD for now? (Although I probably could left uboot and /boot on microSD and then put rootfs on eMMC, but that another story.)

I've read on the forum that support for usb gadget using the µ-usb port on the libre computer tritium needed a kernel reconfigure &  recompile.

I tried to start with that, but during configuration, I've seen full support already.

So, was it supposed to just work ?

I target armbian buster server variant.

my need is to use IP over an usb (and power) cable between a linux machine (x86 and then arm) and a  tritium h5

Thanks in advance
