Re: POG MMDVM firmware compiling error
And after writing (even 56%) remove jumper of MMDVM board and power on Rip,
only PWR LED is lit on the MMDVM.
So I think I failed to write the firm of MMDVM.

Re: POG MMDVM firmware compiling error
I once tried and got ERROR.
When writing to MMDVM the LED of PWR stay lit and ACT is flashing fast.
And stopped at 56%.
It is very strange.
