General Discussion Jul 31, 2021 · Now does there exist a "general purpose JTAG communicator" which I can connect into my PC's USB port and just use a basic API to send read/write requests to it to be executed on the FPGA's JTAG port? I do not know if something like this exists. 3 V 2 +3. By conforming to the J-link connector pinout standard, developers can ensure reliable and accurate debugging and programming operations. The JTAG signal are show along with there pin numbers. Except for TCK, all other JTAG lines should be pulled high via a resistor. JTAG is in use for multiple microcontroller/processor architectures aside from ARM. Like so: AN134 from Silicon Laboratories, Page 1, dated 12/2003! To program each device you will probably need to specify things like the following in your JTAG blaster software: The number of devices before and after the target you wish to communicate with. Practical Example: Locating JTAG Headers / Determining Pinout As mentioned before JTAG lines are often grouped - so when looking at a new platform from a hardware perspective, looking for pin groupings greater than 5 is always a good start. The JTAG controller interface is available on dedicated I/O (DIO) pins in the PMC. Nov 30, 2025 · JTAG Connector A place for an optional 20 pin CTI JTAG header is provided on the board to facilitate the SW development and debugging of the board by using various JTAG emulators. tyssrwzd
