Linux 2.4.19-rmk7-pxa2-adsx4

This version

Only supports AGX and BitsyX boards.

Has a new touch screen driver that provides improved noise handling and better support for calibration. The new driver is compatible with the IPAQ touch screen driver supported in many embedded GUIs (e.g. OPIE, GPE). The new driver is not compatible with the default (microwindows) interface provided in the previous driver.

Does not support USB on the AGX. [Later versions do. -jlackey]

Important Warnings and Requirements

Do not use a connector board older than Rev A on the BitsyX.

To build the kernel, you must use a compiler that supports the Xscale CPU.
You can use the one we used to build the precompiled kernels provided below.
Download arm-2.95.3.tar.gz , untar it in /usr/local/ and add it to your path.
```
cd /usr/local
tar xzf arm-2.95.3.tar.gz
PATH=/usr/local/pxa/bin:$PATH
```

There is an update for the AGX that affects the backlight. To get this update, download and apply the following patch: diff-2.4.19-rmk7-pxa2-adsx4-agx-backlight-fix.gz.

The precompiled kernel image for the AGX has been replaced with a zImage that includes this update.
