STM32F4xx ZumRadio 0.9 not found after update to commit ee07f76bd5af5662e2b3a10188759a88348c9304

I have just updated the firmware in two ZumRadio 0.9 boards and they are both no longer responding to MMDVN.

Here's a copy of the mmdvmhost log for one of the repeaters...

So, I figured I wonder if there's no longer enough memory to run all the modes including FM &ax25 & M17 so I disabled them in Config.h hoping that would solve the problem, but the modem was still not being picked up by mmdvm. So, the next thing to try was to try each serial speed listed in the Config.h (one at a time of course!) and that didn't make any difference.

this repeater is running the current release of pi-star (Pi-Star:4.1.5 / Dashboard: 20210721) as of writing. Is it possible that the version of mmdvm in pi-star is too old and that's the reason for the modem to not be picked up?

You need to use the latest MMDVM Host to match the new firmware. This was outlined in my announcement on the OpenDV@groups.io mailing list. I have no idea when Pi-Star will support it all.

Ah OK, I'm not subscribed to that list, so I rolled back to the #835ef46 November 2020 where Version.h was bumped and rebuilt and uploaded expecting it to jump back to life, but it's now stuck with a NAK to the SET_CONFIG command. I've powered down the raspberry pi (removed power and reconnected) but the modem seems to be wedged in this condition. Am I missing something obvious? Have I not gone far enough back to still be a version compatible with the pi-star mmdvmhost version? (I realise that is a question directed to pistar!)

I used git checkout for the roll back, was that the correct way? The version of mmdvmhost in pi-star is at 20210617 and it was working just fine until I jumped the gun on this update. I suppose it is time to roll up my sleeves and roll my own mmdvm system to take advantage of the current release and hopefully get the modem talking between mmdvmhost and the Zumradio modem!

Don't worry that little voice in my head is laughing saying that I told you so!

Cheers

After some time away from this it occurred to me that I wasn't going far enough back to when the code was changed to what's needed for the newer modes etc, so incrementally kept going back until it worked. FYI it was a June 2020 commit so all is good and working again...
