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://ts7260.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.
• kernel26: some notes on how to compile a 2.6 kernel for ts-7260

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 </li>
• 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.</li>

• 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

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.

Compiling a 2.6 kernel A while ago I discovered the linux-2.6 from ynezz and decided to give it a try. These are my basic notes about my tries

• Get the code from the repo

• Make a default configuration

   make ARCH=arm ts72xx_defconfig
  

• Enable serial console:

   CONFIG_SERIAL_8250=y <br />
   CONFIG_SERIAL_8250_CONSOLE=y
  

• Compile the modules:

   make INSTALL_MOD_PATH=$(pwd)/../modules modules_install
  

• Load the kernel:

   load -b 0x00218000 -m http -h 192.168.1.12 /tmp/vmlinux
   exec -c "console=ttyAM0,115200 root=/dev/tssda1"
  

I used an openwrt image build earlier to test the kernel. Seemed to work pretty good. My openwrt config will be posted later.
