Today I update my STM32F0DISCOVERY ST-Link/V2 from version V2J14S0 to V2J16S0.

I use an evaluaton version oh KEIL (version 4.60.0.0). Before the update I succeed in set breakpoints in my code. After the update I can't set breakpoint. There is some incompatibility beetween the two version of ST-Link and Keil compiler? I have another STM32F0DISCOVERY (not updated) and this works fine. What can I do for downgrade the ST-Link V2 on my board? Thank you in advance. Fabio

Possibly a PC driver problem - have you tried the latest ST-Link USB driver ?

There is some incompatibility beetween the two version of ST-Link and Keil compiler? If the USB driver is no fix, this would be a question to ask in the Keil forum. Not sure if they actively support an evaluation version. But for a downgrade, older versions of the STLinkUpgrade EXE might do the job. But possibly it refuses a downgrade ... I'm going to check this tomorrow, as I had updated a F0 discovery to V2J16S0 today, but not yet tested with Keil.

Sorry, I can't confirm your problem.

It is still working for me, with  uVision V4.60.0 (Evaluation), on WinXP. Building and debugging a stm32f0-discovery example succeeded without any issues. I had installed the ST-Link USB driver only recently (2 days ago), so possibly an OS or driver issue.

I tried to re-install everything: Keil, ST-Link Utility and USB driver.

Now everything works fine. Thank you Fabio
