Question

Has anyone else had issues with STM32CubeIDE 1.5.0/1 ST-LINK version en.stsw-link007_V2-37-27?

Hi, just updated my IDE, which prompted a ST-LINK upgrade to  en.stsw-link007_V2-37-27.

STM32F303RET nucleo. No other hardware. Always been rock solid.

Refused to debug, as soon as I put breakpoints in I get

CM4 Failed to read fpu registers

FAILED to REGISTER Values from the target

Managed to revert my IDE and ST-LINK IDE 1.3.0 en.stsw-link007_V2-37-26 and all working as before.

Cheers

Dan

    Hi,

    I'm also having that issue with STM32H745IIK6 and STLINK-V3MINI with firmware version V3J7M2.

    But it shows immediately after I start debug.

    Everything works fine in ST-LINK Utility, and when I erase the memory I can enter debug normally and it says "Download verified successfully" and I can click resume, my program runs, everything is good, I can suspend program and to the usual things.

    But after a few seconds, it says "Target is not responding, retrying..." and when I try to debug again, I either get the aforementioned error or I get this:

    "Could not read registers; remote failure reply 'E31'".

    Those anyone know the fix to this?

    BR
