portsdown 4 issue

Post by m1cdq » Wed Mar 03, 2021 9:47 am

just upgraded to a pi4 from a pi3 3. New card (sandisk)and software installed and updated. No issues previously only pi changed pi4 2gig
it is working. I receive my local repeater. But after about 10 mins the 7" screen goes black. I tap the right hand side to go back to menu. tap to go back in to receive. All I get " waiting for Minitioune to respond".. If i tap the right hand side of screen again I go back to menu but then every thing freezes and i have to reboot

Software version Buster 202102250
CPU temp 53.6 GPU 52.5
temps and voltage ok

Hi Roger

I'm not saying that it isn't a software issue, but the first thing that I would check is the quality of the USB Connection between the MiniTiouner and the Raspberry Pi. I would then check for power supply ground loops. USB is very sensitive to power supply spikes.

Also if the tuner is plugged into a USB 2 socket, try it in the USB 3 socket - or vice-versa.
