Re: Booting Hurd with a serial console
I don't recall the details, but I think GNU Mach 2.x is the only one
who supports remote debugging via a serial console. GNU Mach 1.x and
2.x should work with getting a serial console on the serial port
I started working on a small document describing the process of
configuring both remote debugging and how to get a serial console for
GNU/Hurd, but haven't written much yet. Infact I haven't even
bothered creating the file yet... :)
For a serial console the following should work:
settrans -cp /dev/com0 /hurd/term /dev/com0 device com0
Add the following to /etc/ttys:
com0 "/libexec/getty 9600" vt100 on secure
Send SIGHUP to runttys (or reboot), and then you should have a serial
console on the serial port of your GNU/Hurd box. Connect to it using
whatever you normally use.
For remote debugging you will probobly need GNU Mach 2.x, in your GRUB
listing add the following:
serial --unit=0 --speed=9600
And add the following options to the kernel line:
-h CONS_COM=1 -d GDB_COM=2 BAUD=9600
Then you should be able to attach GDB to the serial port 1 doing the following:
set remotebaud 9600
target remote /dev/ttyS1
Then you can just debug GNU Mach 2.x using gdb.
Thats all, if something doesn't work, please tell so it can be fixed.
But the above instructions should work, I think...
