Title: [Solved] Problem Installing 2.5.1 via Serial Console Post by: gmurz on Thursday 21 February 2013, 12:07:19 am Hi All,
i am trying to install efwc 2.5.1 on a endian mercury pro (outdatet maintenance) via the serial console. for this i created a bootable usb-stick and editet the syslinux.cfg to get the kernel output on the seriall console: APPEND initrd=instroot.gz root=/dev/ram0 rw console=ttyS0,38400n81 at first the boot looks fine, but then it kepps hanging in a loop: [ 0.000000] Linux version 2.6.32.43-57.e43.i586 (root@andrew) (gcc version 4. 1.2 20070626 (Endian 4.1.2-14)) #1 SMP Wed Aug 10 05:05:15 EDT 2011 [ 0.000000] KERNEL supported cpus: [ 0.000000] Intel GenuineIntel [ 0.000000] AMD AuthenticAMD [ 0.000000] NSC Geode by NSC [ 0.000000] Cyrix CyrixInstead . . . . .

The problem is that it is trying to launch the installer on the "PC" display adapter and you want it to use the serial port. The installer is launched by init and the command line is in inittab in the initial ramfs. Here is a step by step set of instructions.

That was exactly what i am searching for. I will try that over the weekend and report back Title: Re: Problem Installing 2.5.1 via Serial Console Post by: gmurz on Thursday 28 February 2013, 06:20:02 pm OK, next try... with the suggested solution i still get an error loop after booting. so i played arround with the inittab and found a way to get just a login. inittab: ::sysinit:/etc/rc ttyS0::respawn:/sbin/agetty -L 38400 ttyS0 vt100 after boot and login i started the installer with: -ash-3.00# /bin/sh sh-3.00# /bin/installer /dev/ttyS0 Install program started.
