I wonder if it'd be worth having a look instead at the Odroid stock kernel image and the vanilla kernel of the base same version; see what quirks are needed. I will have a look and see if that diff is less overwhelming than the massive gap you're seeing.

@torz77 Without logs and diagnostic information it's hard to tell what is going on because what you're saying is the equivalent of "it doesn't work" Nonetheless I had the same symptoms when my SDcard was dying (bad sectors here and there). The kernel and network layer was loaded in to memory OK, so pings would work, but ssh calls upon extra binaries and files from the SD card and I was getting I/O errors, hence would result in SSH dying which is the connection refused the client sees. I had to connect mine to a display for the duration of a diagnostic session but thankfully it was easily reproducible so the error glared out. A replacement SD card got me there.

Likely a kernel issue at a guess. I went back to an old build using bookworm but with 5.x and had similar issues although I could boot with USB devices plugged in and then detected, I got many USB bus reset errors and the device was unusable. Is the correct route here to file a bug?

OK my experimentation has continued and I've discovered an interesting problem. USB doesn't work. I've flashed a vanilla Hardkernel image (ubuntu-20.04-3.10-minimal-odroid-c1-20200519.img.xz) and all is well, ruling out any hardware issue. lsusb shows the root controller hub on the custom Bookworm armbian build: Armbian-unofficial_25.02.0-trunk_Odroidc1_bookworm_current_6.6.43_minimal.img. I've plugged in a webcam and a flash drive, non of which appear in lsusb nor generate any stimulus within dmesg. I've since done git pulls on the repo so I can't tell exactly which git rev this was built on or from; I'd suggest it dates from my last post, Dec 17 2024. lsusb under the Hardkernel image shows the controller hubs as well as the listing in lsusb, plus dmesg. All seems well. Any one else experience this?

Thanks to torz77, I just resurrected my odroidc1 with the Debian image (which is more than good enough for me!). Thank you!!
