Can you test these commands in u-boot?

mmc list

mmc info

mmc dev 0

mmc part

fatls mmc 0:1

ext4ls mmc0:2

mmc read 0x40000000 0 1

 

It seems like mega doesnt work anymore without login. 

Here are the images on gdrive: https://drive.google.com/drive/folders/1jEIWmzZgT5t39jRz7GwZpFOAdjdQBLtG?usp=drive_link

Did you get an error when using balena etcher? I tried flashing the image myself and it wouldnt create any partitions.

I uploaded an image with a repaired partition table to gdrive and mega.

Alternatively, you can use gparted to repair the image yourself.

Just put: 

sudo gdisk /path/to/Armbian-unofficial_26.02.0-trunk_Orangepi4a_trixie_edge_6.18.0.img

 r (recovery), then d (recreate primary header), then w (write) into wsl or linux.

[L. Jorge Soares]

I did get an alert from BalenaEtcher, when writting the IMG file to SD. It reported not having a BOOT partition.

 

I continued through the alert and the PI board did boot to the prompt results I originally reported.

 

I am going try you image now and will let you know.

@Marvin-03

 

** run the commands to fix partitions on my IMG build, just like you mentioned and it fixed it.**

 

Your Orangepi4a img is working, I am able to BOOT. But I am accessing the board through the console. Confirmation of the boot is below.

 

I also had a look at the partitions from the IMG created of the GIT build and your own image. See details below.
