Now I have replaced my display and have the following problem:
Without a sound card, the display shows the Zynthian logo and below
big red ERROR.
The display is a “Waveshare 3.5inch RPi LCD (B)”.
The same was also set in the webconfig.
If I then switch on the sound card, the Raspberry Pi 3B+ boots
until the display shows error and goes into a continuous loop.
The sound card is a HifiBerry Dac+.
The green LED on the sound card’s circuit board doesn’t light up either.
For counter testing, I used my old setup again
the display PI-TFT-2.8 resistive + the sound card
and everything works as it should.
Now I’ve gotten so far that the red ERROR
can no longer be seen, but the start screen is in one
is in a continuous loop.
It seems that “ALSA” is the problem but I have no idea what to do.
Thank you for reading.
I changed the driver and still the same problem. But I know that the sound card works perfectly with my smaller display. The problem only occurs in combination with the Waveshare display. Greetings
It could be that the waveshare display is colliding with the hifiberry soundcard. You should check the pins used by each device. If there are pin overlaps, there is little you can do and probably you have to look for a replacement.
For general information, I found this out:
The (GPIO18) is not used by your display for “tail light” or “guided” control as this pin is required by every DAC board on the market.
Well, I ordered another display. Greetings Peter
