How do I use 'J-link' in 'st25ru3993-EVAL'?

[Skang.19]

Hello.

Attempt to debug the example code using 'J-LINK' in 'ST25RU3993-EVAL'.

'J-LINK' has been connected to the entire line and no shock has occurred.

But when I try to put the code on the board, it doesn't work normally and it's called "Could not connect to target."

'TrueSTUDIO' is in use and debug settings are converted to 'J-LINK'. 

Please reply. Thank you.

​Hello,

thanks for your question, when looking to the image how you connected the SWD interface looks ok, 3.3V (red) and GND (black) is correct. The white cable should be SWDIO at pin 2. Pin4 must be SDCLK, Pin 6 SWO, Pin8 TDI and Pin 10 MCU Reset.

Did compiling of your project worked correct ?

Currently we offial only support KEIL project with ST-Link V2 debugging, but it should be no problem to use J-Link from TrueStudio as well. If you are able to share your TrueStudio project with us we could have a closer look into the J-Link settings. Please send me an private message if this is possible for you.

Best Regards
