How viable is production with G4 today?

[Antypas.Peter]

I have designed and produced circuits with the F4 and L4, using plain Eclipse for development and SEGGER J-Link for both development and the ICP fixtures at the line.

I have not been successful at getting J-Link Commander to play well with a G431 over SWD (separate issue, to be taken with SEGGER). I cannot get any of the command line utilities I'm using today (st-flash, openocd) to recognize the G4 either, probably because it's too new.

Is there *any* viable path here? Anybody developing and planning for G4 based production right now? What tools are you using? What is your SMT line going to use for programming?

Thanks.

As far as openocd is concerned, the remedy is rather simple: The G4 has a flash controller quite similar to the L4. So essentially, adding the new device ids to the flash driver and to some helper scripts is sufficient: http://openocd.zylin.com/#/c/4807/

You may still encounter some minor problems, in particular for devices with trimmed flash, but these doesn't seem to be available anyway.
