I'm making an arduino-compatible board with a 32u4, but having tremendous trouble with solder bridges. A little searching shows that the 32u4 supports boundary scanning via the JTAG TAP lines (looks like pins 34-39 are the 4 test lines plus gnd/power).
But I'm COMPLETELY baffled on how to proceed, and searching isn't helping any. It'd be nice to build a pogo test jig to boundary-scan the board prior to programming, but I can't find any tutorials or much info at all past the data sheet. Any suggestions?
Thanks!
