MDK ARM 5.28 problem with (Reset and Run)

Hello!

I recently updated to Keil MDK 5.28, and everything worked fine till i downloaded my software and try to start it on my board. Upload worked perfectly like on last version (5.26). Then i noticed that board does not start and i found out that my ST-LINK/V2 debugger does not produce reset signal after upload. I checked settings and my (Reset and Run) function is checked and i also put osciloscope on reset pin and result is as expected (no signal after upload). I upgraded STLINK on latest firmware.

Does anyone have same problem?

Thanks for any help!

  •  Did you contact Keil / ARM about this? It's kinda hilarious that this seems to be an actual bug. I updated the firmware of my ST-Link V2 according to the Keil IDE instructions but this didn't do anything.

    Edit: I am assuming you also didn't connect the NRST-Pin of your STM32? Maybe the Keil-IDE generates the reset like that, which of course doesn't work as the pin is not connected (at least in my case)

  • You definitely have to connect the NRST-Pin of your STM32 to your ST-Link V2. I just did that and it works now!
