Sorry for the late response! Ok -- so the other issues are solved and the rest works now? Try to enable the JAILHOUSE_DBCON [1] in your kernel config and allow your cell to use it by adding the .flag JAILHOUSE_CELL_DEBUG_CONSOLE to your inmate's cell config (see Documentation/debug-output.md), and use jailhouse0 as output path. Then you should at least see the kernel booting. Maybe this already gives you a clue what's going on. As far as I can see, the upstream inmate configs look fine. Are other inmates that use the same inmate config able to use the UART?
