I'm trying to run the ARM-based frame buffer configuration from conf/examples/arm-rv-lcd.cfg with pkg/io/config/arm-rv-eb-mc.devs and QEMU (-M realview-pbx-a9). I can boot the L4 Linux kernel on this (without GUI but just serial I/O) configuration, but I get an error when trying to set up the LCD (see below).
Perhaps the LCD device configuration from the .devs file does not match what hardware QEMU emulates? How can I actually enumerate in the IO server what hardware it actually runs on? Is there a way to do that?
Thanks, Anna
