Hi
I am back…
i did receive a new GPSberry card.
i try first on a PI3, i plugged it and to configured it. GREAT !!! now it is working (see the image attach)
OK my new GPSberry is operational.
Now i go back to my new PI4 and unfortunatly this is the same issue , with strange characters (with minicom or with cat /dev/serial0).
even if i try to upgrade again the Raspbian , this is the same issue
Do you have any clues ?
Thanks

March 13, 2020 at 12:56 am #15433PeterPParticipantIt may have something to do with the CPU frequency. try this
open config.txt
sudo nano /boot/config.txt
add this
core_freq=250
rebootPeter --OzzMaker.com --

March 17, 2020 at 10:14 pm #15546Mark WilliamsKeymasterI tested on two Pi 4. This is what i did to get it working.
- burn image 2020-02-13-raspbian-buster-full.img
- Enable ssh and wireless
- ran raspi-config and disable console of serial and then enabled serial interface
- rebooted
- view serial while BerryGPS-IMU plugged in, using
cat /dev/serial0
- The GPS was reporting errors
- I disabled echo with
stty -F /dev/serial0
- viewing serial now works
