[uClibc]arm development system results

[Andre]

First of all, thanks to all responsible for the uclibc development system images - great idea !!

I had to make the following changes to get running on a StrongARM SA1110 based Intrinsyc CerfCube:

1) Add /dev entry for the StrongARM serial ports:

mknod ttySA0 c 204 5
mknod ttySA1 c 204 6
mknod ttySA2 c 204 7

2) Modify /etc/inittab to start getty on the correct serial port, at the same baud rate as the CerfCube bootloader:

ttySA0::respawn:/bin/getty -L ttySA0 38400 vt100

3) Add ttySA0 to /etc/securetty to allow root logins.

4) Create /home/default (allows default non-root user to login without warnings about missing home directory).

At this point I can login OK, but there are a couple of problems I wasn't able to fix:

5) 'ls' seems to be broken:

[root at uclibc root]# ls
reading directory .: Invalid argument

Run with strace, it gives the following:

[root at uclibc root]# strace ls

6) Bash filename completion doesn't seem to work ??
