Linux/Windows device drivers

You should probably repost your question over in

microsoft.public.developement.device.drivers

From the top of my head I would say you don't have to write a driver at all. At least not because I know for sure that there are drives around which let you bit bang the paralell port.

The normal way to handle this on windows is to use the readily-available "giveio" driver, which allows normal applications direct access to hardware. The application can the access the parallel port directly. A convenient place to look for examples of this sort of thing is something like the msp430 gcc project, or the ColdFire/683xx bdm gdb project, both of which support a parallel-port based debugger tool (jtag or bdm), and support both windows and linux. If you want to use a high level language like python, the msp430 jtag project also has a python parallel port module that should work nicely from either linux or windows.

Thanks, I'll look into it.

My Linux driver is in fact for JTAG programming.

I wonder what throughput you get when programming memory with a tool that uses the giveio driver? Of course it would depend on length of JTAG chain etc, but a rough idea of what's been achieved would be good to know.

Thanks again for info.

What sort of device is it? There are a fair number of open-source projects for jtag support, both as general support and for specific micros, for example
