It looks like ST LINK sleep support broke on IAR EWARM v9.20.4

[Scott Löhr]

Has anyone else seen this?

I have never seen such a problem in years of debugging with EWARM and STM32's through sleep modes: using source and project files that debug fine with EWARM 9.20.2, now with 9.20.4, the IAR IDE is hung on the ST LINK driver as shown in the attached screen shot. IDE is unresponsive until I cause an EXTIO to wake the STM32WB from STOP2. I reported this first to IAR, but the engineer responding to me, Dave, keeps asking for logs, and as you can see from the screen shot, nothing interesting is getting logged. so the IAR support seems to be at an impasse.

Hello,

I reproduced the issue with STM32WB55 on IAR v9.20.4, investigation is on-going.

Best Regards

It looks like this issue is fixed in the latest release v9.30.1:
