1The Intrinsyc CerfBoard is a StrongARM 1110-based computer on a board
2that measures approximately 2" square. It includes an Ethernet
3controller, an RS232-compatible serial port, a USB function port, and
4one CompactFlash+ slot on the back. Pictures can be found at the
5Intrinsyc website, http://www.intrinsyc.com.

7This document describes the support in the Linux kernel for the
8Intrinsyc CerfBoard as of version 2.4.0-test4-np1.
9
10Supported in this version:
11   - CompactFlash+ slot (select PCMCIA in General Setup and any options
12     that may be required)
13   - Onboard Crystal CS8900 Ethernet controller (Cerf CS8900A support in
14     Network Devices)
15   - Serial ports with a serial console (hardcoded to 38400 8N1)
16
17Not supported in this version (yet):
18   - LCD driver/touchscreen interface
19   - UDC (a driver exists right now, but is unstable and slow and only
20     works with the Linux USB)
21
22In order to get this kernel onto your Cerf, you need a server that runs
23both BOOTP and TFTP. Detailed instructions should have come with your
24evaluation kit on how to use the bootloader. This series of commands
25will suffice:
26
27   make cerf_config
28   make xconfig
29   make dep
30   make zImage
31   cp arch/arm/boot/zImage <TFTP directory>
32
33The default config uses a 4MB RAM disk located at 0xc0500000 as root.
34Setting the board to mount root from a NFS partition works, too.
