STM32H747i j-tag debugging

Associate II

Hello everyone,


I am currently working on the SMT32H747i_DISCO board and I was wondering if it is possible to use the Segger J-Link debugger on the Board. There is a j-tag pin out connected to the Dev board which suggests that it should be possible. I didn't have any luck so far. Are there additional ports necessary? Am I missing something. I can't find any documentation to the purpose of the connection. Thanks for any help.


Regards Maikel


I'm sorry I made a mistake. I did use the SWO connector for communications. It is however not working with the J-Link adapter.
