SOLVED - mmdvm single and duplex firmware update problem
Posted: Sat Sep 28, 2019 1:06 pm
Hello,
I have problems upgrading on to raspberry pi the mmdvm firmware.
It stopps with the failure:
serial posix 57600 8E1
failed to init device
My internet recherche, inlcuding threads of our pistar-forum did a couple of outcome:
- detach OLED display on mmdvm modem and set in configuration to none
- check JP1 jumper / joined on mmdvm GPIO connector pins 38 to 40
- make a new sd card from pistar image and import configuration and try to update mmdvm firmware
So I did all this thre things several times, without positive outcome on both raspberry pis. so same failure did occur. Last year, it worked perfectly.
My config for hotspot
- 2 raspberry pis B+ with 26 gpio pin connection with pistar 3.4.17
- simplex mmdvm hat 17.5 MHz (german version), mmdvm firmware installed 1.4.6
- duplex mmdvm hat 12 MHz (german version), mmdvm firmware installed 1.4.8, gpio conncetion and not usb connection to Pi
- 2 oled displays
Pis and mmdvm work very well in both installations.
Due to raspberry pi version B+ which is lower Pi 2, I have to youth pistar version 4.4.17.
So any hints, what could be the problem or what did a miss to recognize?
Thanks to the maker of pistar software and Toshens KE0FHS Website, which helped me a lot beneath pistar website and this forum.
Best regards
