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. 5 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) 17 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. 30 31 32I-Gene Leong, Intrinsyc Software Inc. 33ileong@intrinsyc.com 34 35
