I started with Arduino just over a year ago then quickly moved to the Teensy, and I've come to realize I need the power to hardware debug my projects. Currently I do not have any hardware to do this and have been waiting until I'm more familiar with the ARM chip before digging in.
I have never used hardware debugging and have yet to find the idiot's guide to enlighten me as to the details. For the Teensy2 I have not found anything useful regarding JTag debugging but from the ATMega32u4 datasheet I see PF4,PF5,PF7 are JTag pins. Can JTag be used with the Teensy2 or is there something about a fuse blocking the interface?
With the Teensy3 I see pins D3,D4,D5,E5,F5 are JTag pins. Will JTag or other hardware debugging be possible? Would something like the Bus Pirate be enough or is specific hardware required for the ARM?
Obviously I have not done much research yet, I'm just wanting word whether or not JTag is even possible for any of the Teensys.
Thanks!
