The Intrinsyc CerfBoard is a StrongARM 1110-based computer on a board that measures
approximately 2" square. It includes an Ethernet controller, an RS232-compatible serial port, a
USB function port, and one CompactFlash+ slot on the back. Pictures can be found at the
Intrinsyc website, http://www.intrinsyc.com.
This document describes the support in the Linux kernel for the Intrinsyc CerfBoard as of
version 2.4.0-test4-np1.
Supported in this version:
- CompactFlash+ slot (select PCMCIA in General Setup and any options that may be required)
- Onboard Crystal CS8900 Ethernet controller (Cerf CS8900A support in Network Devices)
- Serial ports with a serial console (hardcoded to 38400 8N1)
Not supported in this version (yet):
- LCD driver/touchscreen interface
- UDC (a driver exists right now, but is unstable and slow and only works with the Linux USB)
In order to get this kernel onto your Cerf, you need a server that runs both BOOTP and
TFTP. Detailed instructions should have come with your evaluation kit on how to use the
bootloader. This series of commands will suffice:
make cerf_config
make xconfig
make dep
make zImage
cp arch/arm/boot/zImage <TFTP directory>
The default config uses a 4MB RAM disk located at 0xc0500000 as root. Setting the board to
mount root from a NFS partition works, too.
