Has anyone encountered this? It could very well be a stupid human trick on my part. There is no ready help available.

I presume the board worked before your attempt at updating the firmware.

If so, you may have loaded incompatible firmware. Otherwise my first though would be that you have not specified the correct board type in the Pi-Star configuration.

What does "sudo pistar-findmodem" tell you?

The Aursinc (aurinc?) board I have runs at 14mhz not 12mhz; the "documentation" (on Amazon) says to flash at 12 but I think that's wrong.

Try running "sudo pistar-mmdvmhshatflash hs_hat" instead (drop the -12mhz).

sudo pistar-findmodem simply returns with no information after a few seconds.

The system did NOT work out of the box and at the behest of the manufacturer, the mmdvmhshatflash hs_hat-12mhz was run.

Firmware update reported ok.

I can use pistar-mmdvmhshatrseset and the lights dance on the board as expected.

Otherwise, it simply cycles constantly through "Opening the MMDVM" and the afore-mentioned error message about not being able to read the firmware version.

Doesn't make sense that you can write to the board but you can't read it. Something is amiss in the config somewhere.

What do you get when you run these commands?

Code: Select all

sed -n '/\[Modem/,/^$/ p' /etc/mmdvmhost
sed -n '/\[Modem/,/^$/ p' /etc/dstar-radio.mmdvmhost

This piece is going back to amazon. I have spent way more time than I paid for it fooling with it. :?

Thanks to all who tried to help! Hopefully I can reciprocate in the future.
