While originally intended for boundary-scan testing of PCB assemblies, to replace bed-of-nails testing, the JTAG port included in many popular microprocessors is also often used for programming and debugging.
"If you have information on how to connect a JTAG probe to a Nokia phone, please let me know."
There are five pins:
- TCK/clock
- TMS/mode select
- TDI/data in
- TDO/data out
- TRST/reset (optional), when driven low, resets the internal state machine.
Except for TCK, all other JTAG lines should be pulled high via a resistor.
WARNING: unconfirmed pinout. Please add links to pinout standard.
20 Pin JTAG PinOut
Which one of these is right?
