JTAG programming? #18

Open cfriedt opened 8 years ago

cfriedt commented 8 years ago

Hi, the PIC32 is fully JTAG programmable as well, and is even supported with OpenOCD.

Are the JTAG pins exposed on this device? Are there any other limitations that would make JTAG programming impossible?

Viewing the schematic here, I see that the TDI, TDO, TCK, and TMS pins are not brought out. I would highly advise that you make JTAG available as well, as it greatly increases the size of your market for this product.

Christopher,

I'm not quite sure what you mean by 'not brought out' - all JTAG signals are already available on the I/O headers. Anyone can hook up a JTAG programmer/debugger to the Fubarino SD if they want to.

Sorry - I misread the schematic. Looks like it does go to RB12, RB13, etc. Thanks!
