ST/GD-link question

(1/2) > >>

Saimoun:
Hi :)

Does anybody know if there is any difference between the ST-Link of STM and the GD-Link of GigaDevice?
Do you think I can use my ST-Link to program a GD32e230x for example?

Thank you
Simon

I haven't heard any issues with using normal stlink. Should be able to program it OK.
The one limitation might be if their software does not support stlink programmer, but that would be a surprise, and other programming software is available.

Doctorandus_P:
Which one?

I'm also sort of interested in the black magic probe, but have not used it and do not know if it supports the GD devices.

And what's this kB nonsense?

bson:
There's nothing processor specific about the programmer.  It's more about how well the programmer is supported by your toolchain.

openocd for example supports all versions of stlink (v1, v2, v3) but not gd-link directly out of the box.

Get a generic stlink if you haven't already, doesn't really matter which one. Stlink v3 mini is also available from digikey for $10.
You can get a bluepill PCB and convert it into blackmagic probe.

The support list is here: https://github.com/blacksphere/blackmagic/wiki/Frequently-Asked-Questions
So any GD32 that is a clone of a ST part would work, but, any custom GD32 part I don't think it would work unless you wrote the driver for it yourself?
