Adding a JTAG port to a LM4f232h5qd design
I am putting together a design and need to be pointed to where I may find the connections for adding a JTAG port using a XDS100v2 or v3 emulator to my design that will allow me to take advantage of CCS5 and its debugging & flashing capabilities. Meaning I need to know the pin connections from my processor to the 14 or 20 pin header. I have searched but may not be looking in the correct areas.
Any help would be great!
I believe this should be helpful
Maybe I did not clearly state what I was trying to do. I purchased a XDS100v2 with the 14 pin connector and I am designing a PCB with the LM4F part on it and I want to make sure I have the pins correctly connected. Here is what I have on paper:
14pin connector LM4F pin Name
1 Pin 117 PC1/TMS
2 Pin 90 /TargetReset
3 Pin 116 PC2/TDI
5 VDD +3.3v
7 Pin 115 PC3/TDO
11 Pin 118 PC0/TCK
I hope that better explains what I am trying to do? Thanks for the responses!
Take a look at the following article as this should provide some clarity on the treatment of the 14-pin connector pins.
You should handle pin 4 (to GND) and pin 9 (connect to TCK as this is the "return" TCK) to the emulator. Some instances I have seen a series resistor added between pin 9 and pin 11 to allow to break that path if necessary.
