Re: (RPI) Changing the tty to an external device and validating functionality

Wow, I now understand why I couldn't get it to come out of RO mode. I also found /boot/cmdline.txt also has it in there. I will tackle this tomorrow and see how it goes. I am going to push up an image to my website soon that has my version of mmdvm (RC4 with trunk BUSTER OS) and also svxlink install...

Re: (RPI) Changing the tty to an external device and validating functionality

back at it again, no idea why those readings are so inconsistant, I hooked up a frequency counter and the crystals are very stable within a few hertz over a period of time. I have sent one board off to a friend who is far more digital setup knowledgeable to look at as well. I am on to another challe...

Re: (RPI) Changing the tty to an external device and validating functionality

I found a reference for those messages, but the results are a bit odd for my board https://github.com/N4IRS/MMDVM-Install/wiki/pos-centre-threshold The pos number is an indication of the detected sync word position. Ideally it should remain constant. If it increments or decrements it is a sign of ti...

Re: (RPI) Changing the tty to an external device and validating functionality

I am giving the compiling a try now to see how it goes. I found a board bug where I needed to invert the inhibit pin, I thought it was active low so the chip has been inhibited. Got that fixed up now, getting lots of red spaghetti on this board now :-) So I got most of the way through compilation, b...

Re: (RPI) Changing the tty to an external device and validating functionality

I will take a look at this further, I found a new problem this morning when checking the PTT, I have active low COS, which is tied to the inhibit pin, looks like I need to rethink that approach as the logic is inverted but I dont see an option to toggle the inhibit logic in the dashboard. I also not...

Re: (RPI) Changing the tty to an external device and validating functionality

Can you recommend some places to get started with configuring the mmdvm and the MD380 rigs to talk to each other. Been fighting this for a bit now and I cant get anything in the logs or dashboard that even looks like the radio is talking to the mmdvm controller. I have confirmed I have audio from th...

Re: (RPI) Changing the tty to an external device and validating functionality

I fired up a second board and checked the logs, I suspect that was something I did the blipped it. I think I might have been testing the programming function through openocd around the same time.
