[SOLVED] J-Link and STM32F4 Discovery

tmohr · Oct 26th 2016, 3:51pm

Hello,

I refer to AN00021 on how to connect J-Link to an STM32F4 Discovery.

It did not work for me and according to this description the solder bridges SB11 and SB12 also need to be removed:

I thought you may want to add this in there. Only after this change I could connect to my STM32F407.

Maybe I missed this point somewhere?

Best regards
Torsten

Maybe think about converting the onboard ST-Link to an "official" JLINK segger.com/jlink-st-link.html and save the hazzle with the external one.

Hi Torsten,

Thanks for pointing that out.
I forwarded this thread to my colleague Martin, who will update the AN accordingly.

Best regards,
Niklas

Thanks for this hint, I bought another STm32F4 Discovery board and tried the description on the page above. All works fine, much less wiring now.

Best regards
Torsten
