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.

Looks like your GIT no longer has the changes for OrangePI4a board available.

 

[Werner]

Looks like stuff got lost due to force-push. Check this how it looked before: https://github.com/rvdr/build/activity?ref=spi-nvme-patches

I updated my patches to the new style (using series.conf) and that took some time. They are back online, as are some new images. I post more updates at the opi discord btw.

 

As far as I know, neither network, spi flash or pcie are working currently.
