Also, this TVBOX contains the less known S9012P wifi chip. However on this github repository some kind of unofficial driver support is available, can this driver get the wifi chip working on Armbian ?

I solved the issue ! I flashed the latest armbian release raw image to the sdcard and plugged it in the TV box. It magically booted from the SDCard and now I have mmcblk2 as a block device. Now I can run armbian-install command to get everything going correctly.

All clear for the PCIe MSI: it is something with that Intel 7260 card. Today, I got two other M.2 Wifis: MT7922 and RTL8822ce, both seem to work on current and also on edge. Thus, I consider this as a success. Here's some screen blurb. // Sven-Ola

Try a different microSD card, and always start with a serial-USB connection to your laptop. After first boot, run htop and if you see the CPU high usage, wait until it is done. Then reboot the orange pi.

I don't know about customizing the initrd during the armbian build process. But this is the way to customize it AFTER you get armbian running in your board https://forum.armbian.com/topic/53568-how-to-add-a-specific-single-file-in-the-initrdimg-ideally-automatically-with-update-initramfs/#comment-221767 I know it is not YOUR OWN INITRD, but maybe you can work with it. Large language models are more useful when the answer exists somewhere in a popular website. If no human has written about it, ChatGPT or Gemini will not give you the answer. Have you tried replacing the uImage file in the /boot folder, with your own initrd, converted to uinitrd?
