These page is about the stuff I missed/needed/forgot about the TS-7260. It's just all about stuff I stumbled with.

It should always be reachable at http://ts7620.tisnix.be/ which will be a redirect to the current location.

Kernel Compiling: you need to recompile the kernel if you want to use the I2C-patch or the serial-patch.
I2C patch: this patch makes it possible to use the GPIO pinheader as a bit-banging I2C device.
bat3: the bat3 code to control the TS-BAT3 missed some features. This is a try to add them.
fconfig: redboot can be used while booting but you can also manipulate the setting while running linux.
serial: by default the kernel only supports 6 COM ports. This patch fixes this issue.

If you think I could help you, you can always try to contact me at wimpunk+ts7260 at gmail dot com. If my spamfilter isn't to aggresive you'll get an answer.

Kernel Compiling

My kernel patches are patches against the default kernel provided by Technology Systems. These are the steps you need to take to get your kernel compiled:

Extract the embedded arm kernel: tar -xvzf tskernel-2.4.26-ts11-src.tar.gz
After extracting the kernel you can patch it with either my i2c-patch or my serial.patch or you could apply both
Fix the crosscompile issue. By default the TS-kernel expects to find the crosscompiler on something like '../../tools/crosstool/arm-9tdmi-linux-gnu/gcc-3.3.4-glibc-2.3.2/bin/' but I think most people didn't installed their crosscompiler there. Mine didn't even had that name. You can either change the Makefile or add CROSS_COMPILE to as a make parameter.
Import the old configuration:
cp ./arch/arm/def-configs/ts7260 .config make oldconfig
Compile the kernel:
make menuconfig make bzImage make modules

Note: The current 2.4 kernel doesn't compile with gcc-4.0.1 - at least not the one I tried

I2C patch

This patch is all about using GPIO as a bitbanging I2C controller. Get the i2c-patch and patch the kernel :


		cd linux24 && patch -p1 < i2c-patch

Enable i2c by running make menuconfig. You can find the option on: character devices > I2C support > I2C bit-banging interfaces > Ep93xx I2C using GPIO pins.

Feel free to post your comment here or you could post them on a google group or contact me directly at wimpunk+ts7260 at gmail dot com

I've been testing the patch on a TS7260. I load the module as insmod i2c-ep93xx [sda=sdapin] [scl=sclpin] with optional params sda and scl. Default values are set at compiletime.

bat3

It's all in googlecode: see the bat3 site on google code
Original messages about the bat3 can be found on the ts-7000 forum on yahoo
I've opened a googlegroup: check bat3 discuss

fconfig patch

original code on http://andrzejekiert.ovh.org/software.html.en and the patch can be found here. Untar the fconfig code and patch it this way:
tar -xzf fconfig-20071021.tar.gz cd fconfig patch < fconfig-offset.patch
I used it this way: fconfig -d /dev/mtdblock/2 -o 0x2fb000 -w -n boot_script_timeout -x 10
my post about this patch

Note: this patch isn't needed anymore. fconfig-20080329.tar.gz and later alreadly contain this patch.

Modifying ts-kernel for more than 6 ports

The default kernel only uses 6 ports but I needed more. There is a post about this in the yahoo group and I created serial.patch to fix it.
