moved to off-topic since op is not using Armbian.

I'm sorry, but I don't really understand what a microSD card has to do with the problem above to perform system updates?

Hello, i'm trying to make Arch work on my H3, it boots to uboot, loads fine and says RAM size and reads /boot/boot.scr, but when it tries to ext4load something it gives a error of ` ** fs_devread read error - block` and ` ** No partition table - mmc 0`, everything after `321 bytes read in 24 ms (33.2 KiB/s)` loads by arrays of pixels, i never seen these before on Armbian, H3Droid or any other img file. [ EDIT ] Turns out, U-Boot defaults to 400000hz on SD card while saying its mode is SD High Speed (50MHz), i still cant fix the issue...

I see that this configuration is a kernel build feature, not an armbian-developed function: https://cateee.net/lkddb/web-lkddb/INITRAMFS_SOURCE.html https://unix.stackexchange.com/questions/479415/how-does-linux-know-where-the-rootfs-is So, you can post your question in many more linux discussion places. I hope you get the answer (and share here). Have you ever got this INITRAMFS_SOURCE configuration work, outside of Armbian... for example building the kernel from source by itself?

Thanks @robertoj as a matter of fact this is my own custom initial ramdisk. I've been running it as a standalone file for some time and it works great but now I want to integrate it inside the kernel itself. for this I need to set CONFIG_INITRAMFS_SOURCE during the make process.
