The Intrinsyc CerfBoard is a StrongARM 1110-based computer on a board
|
2 |
|
|
that measures approximately 2" square. It includes an Ethernet
|
3 |
|
|
controller, an RS232-compatible serial port, a USB function port, and
|
4 |
|
|
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
|
8 |
|
|
Intrinsyc CerfBoard as of version 2.4.0-test4-np1.
|
9 |
|
|
|
10 |
|
|
Supported 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 |
|
|
|
17 |
|
|
Not 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 |
|
|
|

|
|
In order to get this kernel onto your Cerf, you need a server that runs
|
23 |
|
|
both BOOTP and TFTP. Detailed instructions should have come with your
|
24 |
|
|
evaluation kit on how to use the bootloader. This series of commands
|
25 |
|
|
will suffice:
|
26 |
|
|
|
27 |
|
|
make cerf_config
|
28 |
|
|
make xconfig
|
29 |
|
|
make dep
|
30 |
|
|
make zImage
|
31 |
|
|
cp arch/arm/boot/zImage
|
32 |
|
|
|
33 |
|
|
The default config uses a 4MB RAM disk located at 0xc0500000 as root.
|
34 |
|
|
Setting the board to mount root from a NFS partition works, too.
