I'm totally new to embedded linux, but have some expierence with i386-versions of linux. I'm working with an MPC860 on a MBX860-004 board. I already managed to get a nfs-version of embedded linux (hardhat) to run. But I have trouble to build linux with initrd - the start-sequence shows as follows: ==================================================================================== [snip] Linux/PPC load: root=/dev/ram0 Uncompressing Linux... done. Now booting the kernel Linux version 2.2.14 (bal2bk@bkrfs31) (gcc version 2.95.2 19991024 (release)) #1 5 Mon Apr 23 09:39:59 MEST 2001 Boot arguments: root=/dev/ram0 Decrementer Frequency: 2500000 Calibrating delay loop... 39.73 BogoMIPS Memory: 13308k available (664k kernel code, 448k data, 36k init) [c0000000,c1000 000] Dentry hash table entries: 2048 (order 2, 16k) Buffer cache hash table entries: 16384 (order 4, 64k) Page cache hash table entries: 4096 (order 2, 16k) POSIX conformance testing by UNIFIX Linux NET4.0 for Linux 2.2 Based upon Swansea University Computer Society NET3.039 NET4: Unix domain sockets 1.0 for Linux NET4.0.

I already checked the docu and the older postings and tried everything I found with no success: bootargs: - root=/dev/ram rw - root=/dev/ram0 rw - init=/dev/ram - init=/dev/ram0 - console=/dev/ttyS0 The ramdisk is smaller than 4096 kb so there shouldn't be any problem ...
