V1.1.0, segger j-link support gone?

Hi I installed STM32CubeIDE V1.1.0 and now I can't select J-Link as a debug probe, only ST-link (GDB & OpenOCD).

I get the J-link if the project was created in an older STM32CubeIDE version, but not in the new 1.1.0.

Any hints on how to enable J-link?

The internal weekly build we do has fixed this so you will be able to use J-link in the next version of CubeIDE. I've tested it myself and now there's a pop-up warning that there's no support if you would choose a dual-core H7 with J-link (or some other incompatible probe and target) instead of filtering.

Sorry I don't have a solution for you but I am having the same problem. In my case I fortunately had an STLink V2 laying around which is working fine for me. It might be a little slower to load but fine for at least general debugging so far. Also at $29 vs hundreds for the JLink I think they are a bargain.

@BillR​ I have one to, but I want to use System View from Segger to debug FreeRTOS. Its nice to have unlimited break points and better speed as well.

@Cartu38 OpenDev​  I use STM32H753.

@Markus GIRDLAND​ Is there any solution or workaround?

The J-link option is disabled on all H7 devices. This is because the dual-core H7 devices does not have J-link support. However, this gets the negative side-effect that single core H7 devices gets blocked as well.

I don't believe there's a workaround but I know the debate about whether to block these devices or not is still ongoing so I will lift this thread as an example of negative consequences that can come from this.

Please do so

After reading the release note in V1.1.0 that SEGGER is supported, we bout a J-link only for this..

I confirm STM32H753 sounds locked on my side too.

How J-Link does unlimited breakpoints? IIRC number of breakpoints is limitation of the MCU, not of the debugger dongle?

The reflash the flash sector where the breakpoint resides.
