JTAG support


#1

What boards support a JTAG signals (connection)? Whether or not the socket is mounted is not my question. Nor am I asking what they are used for. Thank you.


#2

All of them. Are you interested in a particular board?


#3

Good!
Yes, my initial goal is to rapidly integrate a SoC with an H-bridge / DC solenoids. I need SoC to drive GPIO / PWM signals. I am familiar with .Net Microframework…

All of the boards are interesting, those that are pre-mounted are better avoiding the precision soldering - at this stage.

I have a J-Link. I think the GHI JTAG module ‘may’ be handy, but I didn’t find the corresponding JTAG signals on the Cerb40 II for example…

Do you have a suggestion? A favorite?


#4

This can be done using managed code. You should be able to debug your code using visual studio. Don’t really need a JTAG for that.

@ jsredmond - As @ Architect has mentioned, no need for JTag for what you have mentioned.

If for some reason you do want to use JTag for native development, you can check the schematic. According to that the following are the pins you would be interested in

SWD:
SWDIO - PA13
SWCLK - PA14

J-TAG:
TDO - PB3
TDRST - PB4
TDI - PA15
TCK - PA14

Here is the schematic
