So, with nothing to lose I’ve been trying. I can get it to connect over wifi, and I’ve tried QGC and MP, on mac, windows and Ubuntu. They will all connect to the quad but I can’t seem to get anything to go into the firmware flashing mode.
I have a sinking feeling that flashing firmware over wifi is just a bit too much to ask. Has anyone got it to work? Is it possible? Or do I need to resign myself that this board will be on AC4.2.0 till the end?
And you need to download software from ST.com to get the STM32 ST-Link Utility (yes you will need to fill a profile for download). There are many tutorials to use this tool and Yes you an use it to power the PixRacer @ 3.3V
That did the trick! Thanks. Was a bit of cluster fighting with permissions, and admin rights blah blah blah. But it worked. I was worried that uploading the bootloader through this port might reset everything but that doesn’t seem to be the case and all my parameters still seem to be in place.
