ST-LINK RST pin

[SL-RU]

Hello!
I'm now required in force hardware reset of stm32 before debug using optional RST pin on the st-link. In the keil this option just works by default, but st-utility don't use RST at all. Is that feature implemented? If not, is is possible to implement?

You should use --reset this triggers a RST pin reset IIRC.

~$ sudo st-util --reset
st-util 1.2.0-119-g4209e4b ((null))
st-util: unrecognized option '--reset'
2016-09-18T23:31:36 INFO /home/lyra/prg/stlink/src/common.c: Loading device parameters....

Didn't work =c

With st-util it should automaticly reset the target when started:
https://github.com/texane/stlink/blob/master/src/gdbserver/gdb-server.c#L181
https://github.com/texane/stlink/blob/master/src/gdbserver/gdb-server.c#L202-L204\\\

Could you try adding:
https://github.com/texane/stlink/blob/6dadc9faa1e899b6f7a37c92f1c7fe4f74b7dd75/src/tools/flash.c#L189

And see if this helps?

[SL-RU]

Yep, that helped! Maybe it need to be included in the release by default or by arguments?

[xor-gate]

I will add this behaviour in v.1.3.0 then it is the same as st-flash. Only this is available for stlink/v2 programmers.

I have just merged a possible fix from PR #534. Could you test latest master?

[SL-RU]

Yep, now it's working fine, thanks!
