OpenMarine

Hello,

Upgraded raspberry pi 4 and opencpn 5.6 and seems like the picanm nmea0183 is no longer outputting nmea data on /dev/ttyS0 or /dev/ttyAMA0. Meaning now my vhf which was previously getting the GPS details is no longer getting them

I have gone through all the setup details could find but still not working. 

I have also tried to configure the serial port manually from /boot/config.txt like below with no luck.

#https://azat.cc/2020/09/28/RPi-serial.html
dtoverlay=pi3-disable-bt
#UART0 aka ttyAMA0 pin 14,15
dtparam=uart0=on
#dtoverlay=uart1,txd1_pin=14,rxd1_pin=15
dtoverlay=uart1,txd1_pin=32,rxd1_pin=33

If anyone has some troubleshooting ideas please let me know.

thanks.

Did you ever figure this out? I'm having the same issue. The serial port works fine with Openplotter 2, but a fresh install of Openplotter 3 results in a non-working /dev/ttyS0.
