Just my opinion…
Hardware->Fez Panda web page say:
[italic]FEZ Panda also includes JTAG access for those who wish to use their own firmware instead of NETM[/italic]
As it is not true at the moment, I suggest you to remove that paragraph from the page until you release the code to re enable JTAG.
Good point and I will ask the guys on when will this be available.
Note that this is not “enable JTAG” but it is “erase everything and enable JTAG” but it wouldn’t matter to you because I think you have knowledge in the processor and you are going to compile/load C code. Or you will be using fezopen firmware
