I've been researching alternatives to SAM-BA for programming netduino minis using JTAG. I was wondering if someone could recommend a good JTAG-ISP programmer confirmed to work with the netduino mini for that purpose? Thanks, -Fabien.

Hi Fabien, JTAG programmers work via the JTAG pins on the microcontroller, which are not exposed on the Netduino Mini. Chris

Ok. Is it possible to load the TinyBooterDecompressor.bin on a blank netduino mini using the exposed SPI pins? I believe that the answer is 'no', but I'd like to be sure. Thanks, -Fabien.

Unfortunately, this is not possible. AT91SAM7X microcontrollers do not support programming cannot be programmed via SPI.

Edit: Corrected ambiguous meaning (AT91SAM7X microcontrollers support programming over SPI, i.e. they can be used to program other ICs).
