This maybe a bit obvious, but are you sure the swtiches on Brutus are set
properly? There is a mistake in the Intel documentation and swtich 14
should be NO DOT (DRAM). Note on a clean reset, the numeric LED display
shouldn't display anything.
Which ramdisk image are you using? The perfered one for Brutus I belive is
the one from Zsolt Kiraly. If you don't have this, I can send a working
ramdisk.gz & 2.2.12 kernel with sound and video support for Brutus;
Nicolas P. has compiled a nice patch & script that makes compiling the
kernel for Brutus much easier (all the correct default options are choosen
and such by the script). Use the np12 patch, the np13 doesn't seem to
work (yet).

After bootstrapping my kernel and loading the ramdisk this is what I got.
stty on cua0 gave me:
speed 115200 baud; line = 0;
min = 32; time = 1;
ignbrk -brkint -icrnl ixoff -imaxbel
-opost
-isig -icanon -echo -echoe -echok
setserial gave me
Line 0, UART: 16550A, Port: 0x03f8, IRQ: 4
Baud_base: 115200, close_delay: 50, divisor: 0
closing_wait: 3000, closing_wait2: infinte
Flags: spd_normal skip_test
My Angelboot opts file is:
base 0x8000
entry 0xc0008020
device /dev/ttyS0
options "9600 8N1"
baud 115200
otherfile ramdisk.gz
otherbase 0x800000
My go script is:
#!/bin/sh
#arm-linuxaout-strip linux/vmlinux
angelboot/angelboot -f opts /home/dfer/armbuild/linux/arch/arm/boot/zImage
I used the Intel document for setting up my Brutus board for Linux
developer.intel.com/design/strong (application notes, Linux on the SA-1100
platform).
There was a mistake in setting up glibc I believe but it's correct for the
rest...
I can send my Angelboot program / my working Linux kernel / working
ramdisk.gz image if need be.
Check :
ftp://ssdl-redstone.stanford.edu/pub/ramdisk.gz for the Ramdisk image
that's I'm using / works well...

If you find out, I'd like to know too.
Good luck and make sure Brutus doesn't betray you too =).
