I am new to this whole endeavor and I am attempting to SD-cardless boot my orange pi zero 2 and after nearly a week of playing around have it nearly working.
I have custom compiled Armbian 23.08.0-trunk with Bookworm and 6.2.16 kernel with ROOTNFS set to Y
I have unpacked rootfs to my NFS server
I have setup PXE booting via pxelinux.cfg/01-<mac address>
I have u-boot working from SD Card ( It technically works from SPI but gives temperature error every boot of kernel)
I can boot all the way into a functioning OS.
My problem is that while PXE booting allows for loading overlays, I cannot load a fixup.scr or similar via PXE from what I can tell. I have managed to get a <SERIAL>.img made and it downloads it via TFTP but then appears to do nothing with it. So how would I go about do remedying this ?
