[Christian T. Steigies]

There was no mail on this list in february, or did I misconfigure my mail
filters again?

I got that far now also:

Linux version 2.6.10 (mattw at etna) (gcc version 3.4.0) #1 Mon Dec 12 16:51:05 MST 2005
starting up linux rev 0.2: startmem 0xc02cc000, size 61MB
Built 1 zonelists
Kernel command line: root=/dev/ram
PID hash table entries: 512 (order: 9, 8192 bytes)
RTC driver is not initialized yet, returning 1970.

Memory: 62160k/65536k available (2104k kernel code, 1064k data, 112k init)
Mount-cache hash table entries: 1024 (order: 0, 8192 bytes)
NET: Registered protocol family 16
Linux/m68k PCI BIOS32 revision 0.05
ColdFire PCI Host Bridge (Rev. 0) detected
PCI: Probing PCI hardware
ColdFire internal SEC driver version 0.11

and hangs...

How do I set the root device to nfs, with set cl? Does not work for me yet,
any pointers? I haven't flashed anything yet, I run it all from RAM.

But the thing that looks promising is this:

root at skeeve:/tftpboot/ltib/rootfs/bin>file busybox
busybox: setuid ELF 32-bit MSB executable, Motorola 68020, version 1 (SYSV), for GNU/Linux 2.4.3, dynamically linked (uses shared libs), stripped

So userspace programs might work out of the box?

BTW my board/dBUG says:
ColdFire MCF547X on the M5474LITE
Did I get a "small" one?
