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 ?

It may have something to do with the CPU frequency. try this
sudo nano /boot/config.txt

I did a Fresh reinstallation of Raspbian on my PI.
Setup again Serial and GPS daemon
Still strange characters using Minicom or cat /dev/serial0
Need help please, should be great to be able to use my PI4 with BERRYgps

what Raspbian image file are you using? I will test it here on a Pi 4March 17, 2020 at 2:18 am #15527March 17, 2020 at 10:14 pm #15546
I 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
- view serial while BerryGPS-IMU plugged in, using
- The GPS was reporting errors
- I disabled echo with
stty -F /dev/serial0
- viewing serial now works
