We have been able to port the Linux on this board. But we do have some issues for which I will appreciate if some one could help me. Implementation details: ----------------------- We have used Mission Critical Linux 2.4.5-Pre 5 (derived from debian distro) and PPCBoot 1.0.4 as our base versions. I used the file system meant for NFS mount from the mission critical linux web site. We made necessary modifications to the software to work on our custom design. I am able to boot Linux successfully with a NFS mounted file system and a Ramdisk (I could test upto 128MB size) based file system. But this was possible only when I bypassed the /sbin/init and run the "Bash" shell directly. I made changes to init/main.c to run the shell directly after successful opening of the /dev/console. Bypassing of /sbin/init at boot time is inevitable until we integrate a MPSC port based serial console driver with our linux system. We have a crude one (emulates the low level UART functions using MPSC) that just works. We have the following difficulties: ---------- - PING command does not work The erro message I get is "ping: unknown protocol icmp" - Telnet program does not work which tells me that the service is unknown. The error message I get is "telnet: tcp/telnet: unknown service" What can be the issue? I suspect if any of the boot script is not done. I ran manually /etc/init.d/rcS and /etc/rc3.d/* (my inittab says run level 3) from the bash prompt. This did not help to solve my above problem. I assume that TCP/IP is fine because I have performed NFS mount of the root file system and can access all the files. The booted OS seems to be stable as I have run some complex Linux applications and also able to build new Linux images. With best regards, Murali ** Sent via the linuxppc-dev mail list.
