That would be the next step. Indeed, without JTAG I don't see how anyone
programs the Due, because of total absence of debug facilities; and it
does add considerably to the price (not that I can't afford it, just
seems a bit much for the hobbyist market). You're talking about
something like 3 times the cost of an STM32F4 Disco board, which has the
STLINK interface on-board and a straightforward and free software
solution for gdb; things stop, ^C, get a traceback from
last_chance_handler, on to the next problem.
