Boot logs for SHELL_TYPE=UEFI_BIN adn SHELL_TYPE=BUILD_UEFI: http://81.95.197.197:7777/aciqabilaw http://81.95.197.197:7777/ijopesosuy It would be great to have the same for Shell application. Board schematics is open and available here: http://www.pcengines.ch/schema/apu2c.pdf You can see that serial is exposed through LPC. I tried to modify PcdSerialUseMmio to TRUE, but it doesn't seem to affect anything. Linux say "ttyS0 at I/O 0x3f8", so using IO seems to be fine. > and/or whether > "CorebootModulePkg/Library/BaseSerialPortLib16550/BaseSerialPortLib16550.inf", > > > which SerialDxe depends on in the CorebootPayloadPkg build, is > appropriate for your hardware?

I was able to get some results after removing: DebugLib|MdePkg/Library/UefiDebugLibConOut/UefiDebugLibConOut.inf from Shell.inf section in DSC. Boot log: http://81.95.197.197:7777/isenazutac As you can see I'm getting some logs from Shell entry point and it looks like DoShellPrompt start, but it doesn't appear on serial. In DoShellPrompt thing wait on ShellInfoObject.NewEfiShellProtocol->ReadFile so it seems no input from serial is accepted. Any further steps appreciated. I believe I need no stuff related to GOP, maybe it cause some problems ?
