Re: MMDVM HS HAT Error - Failed to Init Device
Thank you KE7FNS and F1RMB (Daniel) for taking the time to try and help me. I truly appreciate the help in trouble shooting. I've learned a bunch, and even last night I thought I might as well try a new Pi image (which I have never done before), so I grabbed a spare micro SD card, dl the Pi firmware...

Re: MMDVM HS HAT Error - Failed to Init Device
It is often possible to fix this but it involves removing the OLED panel as the TCXO in question is underneath it. If you are not set up for this I would suggest returning the board for a refund if you bought it via ebay or similar. Thanks Brian, the JumboSpot is almost 2 years old and I purchased ...

Re: MMDVM HS HAT Error - Failed to Init Device
Thanks Daniel, I didn't know that and will use the USB socket by the corner. I did try both USB sockets, and didn't fix my Pi 0 + mmdvmhshat communication error.

Re: MMDVM HS HAT Error - Failed to Init Device
All that is needed is to first locate the pads for the jumper on the PCB (You haven't mentioned which hat you have, but if you tell me the text that is written on the PCB I'm sure I can dig up a photo of the PCB), then use a pair of metal tweezers or a paper clip and touch the two pads, and then po...

Re: MMDVM HS HAT Error - Failed to Init Device
Yeah, thats a pretty common issue. Heres a way you can test the serial port, just make sure you substitute /dev/ttyAMA0 where he uses /dev/ttyS0 (you might also have to install minicom, I can't remember if it is included in the image or not. sudo apt install minicom https://medium.com/@amitasinghch...

Re: MMDVM HS HAT Error - Failed to Init Device
KE7FNS, I turned on logging on the pistar admin dashboard, and I think you are correct that there is a communications problem b/w the pi 0 and mmdvm hs hat board. See last two entries in the below log. Starting logging, please wait... I: 2020-02-17 23:08:17.902 This software is for use on amateur ra...

MMDVM HS HAT Error - Failed to Init Device
JumboSpot w/Pi0 3.4.17 with mmdvm hs hat v. 1.4.27. Couple days ago I notice my JumboSpot will not longer initialize the mmdvm hs hat. Tried several sudo pistar-mmdvmhshatflash hs_hat commands and receive at the end an error code "Failed to init device". Below is the log file for reference...
