Hello,

I am trying to use my JLink Ultra+ with stm32h7 nucleu 144 board. I followed the instructions on:

https://gnu-mcu-eclipse.github.io/developer/j-link-stm32-boards/

 

but could not make it work, after connecting all the pins, i removed the CN4 jumpers. At this point i see that the probe senses the board, but the sw4stm still gives me an error about unconnected board....

Has anybody been able to use an external JLink probe with a nucleu 144 board?

I am using sw4stm IDE.

Thanks,

Evgeny

I would connect to the target using the CN4 SWDIO/SWCLK pins, currently you are talking back into the ST-LINK, not the target

Use the JLink Commander tools to check connectivity/function.

Watch the NRST and SWO connectivity, and remove solder-bridges connecting to the on-board ST-LINK

Just to make sure i understood you, the solder bridges need to be removed are SB110 (SWO) & SB111 (NRST)?

Yes, the schematic should be illustrative of this also.
