Hi,
I tried to use Nova without Bender with Multiboot2. Basically it works, but when I omit Bender, there's no serial output from either Nova or Genode. I couldn't find out what Bender does different to enable serial on Nova.
My grub2.cfg looks as follows:
set timeout=5 serial --unit=0 --speed=115200 terminal_output serial console terminal_input serial console menuentry 'Genode on NOVA' { multiboot2 /hypervisor hypervisor iommu serial novpid novga module2 /image.elf image.elf }
What is missing to enable serial on Nova alone?
Regards, Johannes
PS: It also seems that Benders Multiboot2-header [1] is not specification conform. The tags type and flags are defined as double word but according to the specification [2] these are u16 so this should be a word only.
