SXTOOLS

For now we have only a simple parallel port programming interface for In-System-Programming of Scenix/Ubicom SX48/52 microcontrollers. Schematic below. The circuitry is very simple, you can replace the transistors by any comparable types. The JP1 connector has a SX-Key compatibe pinout, you can plug this for example on the USBIO24 modules from http://www.gigatechnology.com/.

Before accessing this interface first stop all services and unload all kernel drivers accessing the parallel port.

Then load the lowlevel driver module by entering in the driver directory:

# make insmod

Now you can read and write the EEPROM of the SX48/52 using the scenix2 program located in the tools directory.

Source tarball and CVS repository is located at http://sourceforge.net/projects/sxtools/.
