Hi there! I'm trying to find out why my setup is not booting on a real machine (some Dell PowerEdge R210 node; ned says it cannot find rom/l4re), but I'm unable to redirect output to the serial console.
I'm able to use the serial console for both grub and linux, so it's not a hardware issue. An excerpt of my grub2 configuration:
serial --unit=1 --speed=115200 --word=8 --parity=no --stop=1 terminal_input serial terminal_output serial # ... # for the linux entry linux /vmlinuz-3.16.0-4-amd64 root=UUID=7573ed62-a910-4b97-a577-dde47a16f87a ro console=ttyS1,115200n8 quiet
Now, here's the entry I'm using for L4, which never gets me any output on the serial console:
menuentry 'Test' { set root=(hd0,1) multiboot /l4/bootstrap -serial module /l4/fiasco -serial_esc -comspeed 115200 -comport 1 module /l4/sigma0 module /l4/moe rom/test.cfg module /l4/l4re module /l4/ned module /l4/test.cfg module /l4/bin/test }
For GRUB2, the the config needs to look like this:
menuentry 'Test' { set root=(hd0,1) multiboot /l4/bootstrap bootstrap -serial module /l4/fiasco fiasco -serial_esc -comspeed 115200 -comport 1 module /l4/sigma0 sigma0 module /l4/moe moe rom/test.cfg module /l4/l4re l4re module /l4/ned ned module /l4/test.cfg test.cfg module /l4/bin/test test }
I.e. the first argument is the path where GRUB2 finds the file, the second is the path that is presented to the OS. comspeed and comport are the default so you can leave them out.
