Problems to program new STM32F0 with D-LINK V2 under software-reset.

Hi,

my problem is, that sometimes the software can't find the device, if I want to connect the F0 to program it the first time. I want to do it with a software reset, not a hardware reset.

Every time I have that issue, I can find the device after try to connect to it with a hardreset.

After programming it, it's no problem to find it again.

And it's not always so, sometimes it works without any problems, so I don't think it's a mistake in the design.

Does somebody have an idea why it sometimes work and sometimes not?

Thanks for the help.

What is a 'D-Link' ?

Did you mean, 'ST-Link' ?

Sorry, yes....ST-Link

Don't know why I had in head the D-Link, maybe because I've done some Network in the last time..

Hm, it's not realy the same...

I use the BOOT0 as BOOT0, and as I say, sometimes it works to connect the device to the ST-Link utility with the software reset, and sometimes just with a hardware reset...
