This page outlines how to build a Linux binary rom image for the WebPal. There is the full sources for the kernel, utilities and romdisk builder. Busybox and uClibc was used to create a cramfs which fits inside of the 1 Meg Flash.
TopInstalling an ARM toolchain
First we need a toolchain, this is a cross-compiler that will create the binary image to load into the webpal Flash SIMM. Do not bother to ask me about CygWin or other non-linux toolchain, I will
ignore you, if you are going to develop for a linux target then use a linux host.
I use the toolchain from ftp : //ftp.arm.uk.linux.org/pub/armlinux/toolchain/cross-2.95.3.tar.bz2
. Grab a copy for yourself. Warning, this is a 35Meg binary, it will take a while to pull it off with a 56K modem! Next, login as root and 'mkdir /usr/local/arm', this is where the toolchain will live. Now install the images with 'bzcat cross-2.95.3.tar.bz2 | tar xCf /usr/local/arm -'. Finally, add '/usr/local/arm/2.95.3/bin' to your PATH. You are now ready to build ARM binaries.
TopGetting buildroot-webpal from cvs
Ensure that you have the cvs binaries installed on your machine, then login to my cvs with 'cvs -d : pserver : email@example.com : /home/cvs login' and press <ENTER> when prompted for a password (none needed). Then fetch the buildroot-webpal module with 'cvs -d : pserver : firstname.lastname@example.org : /home/cvs co buildroot-webpal'. You now have the build system for the webpal.
TopBuilding the binary
it becomes very simple, just 'cd buildroot-webpal' and type 'make'. The Makefile will pull in all needed sources (approximately 26Meg), patch & build them, and eventually create a rom-image.bin in the build directory. This is what you will place into the Flash SIMM by what ever method you have chosen. For myself, I built an adapter
for my Needham's EMP-30 device programmer
to program the SIMMs, others use the bootp to do their programming.
TopISA Multi-Function Card
I have been working on an ISA Card
that has : Quad Serial port (two RS232, two RS485), Compact Flash socket, 2.5" IDE connector, 10BaseT ethernet and a breadboard area.
