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

6This document describes the support in the Linux kernel for the Intrinsyc CerfBoard as of
7version 2.4.0-test4-np1.
8
9Supported in this version:
10   - CompactFlash+ slot (select PCMCIA in General Setup and any options that may be required)
11   - Onboard Crystal CS8900 Ethernet controller (Cerf CS8900A support in Network Devices)
12   - Serial ports with a serial console (hardcoded to 38400 8N1)
13
14Not supported in this version (yet):
15   - LCD driver/touchscreen interface
16   - UDC (a driver exists right now, but is unstable and slow and only works with the Linux USB)

18In order to get this kernel onto your Cerf, you need a server that runs both BOOTP and
19TFTP. Detailed instructions should have come with your evaluation kit on how to use the
20bootloader. This series of commands will suffice:
21
22   make cerf_config
23   make xconfig
24   make dep
25   make zImage
26   cp arch/arm/boot/zImage <TFTP directory>
27
28The default config uses a 4MB RAM disk located at 0xc0500000 as root. Setting the board to
29mount root from a NFS partition works, too.
