Free JTAG programmer for AT91EB55 evaluation

Wed Oct 19, 2016 10:14 am

Hi,
i have done a JTAG ICE based parallel port programmer for the AT91EB55 evaluation board.It works (in the most cases) fine. The only thing you need is a programing adapter which you have made by yourself (at the moment). But it seams that it will also work with wiggler compatible adapters.

At the moment there are the following limitations:
- only for AT91EB 55 or similary boards (same controller and the same flash)
- only usable for the second flash area (jumper in USER position)
- only 64 kByte
- linux host with free parallel port at address 0x378

I can download 64kByte in approx. 25 seconds.

Is anybody interested in this? If so, i could expand the program.

Best regards,

Before continuing, please check the OpenOCD project. You may be re-inventing another wheel.
