ORAM 2405: fresh installation but ERROR

Building Zynthian
1

I have this HW:
• Raspberry RPi5 4GB
• 5" TFT LCD display Capacitive Touch Screen DSI Connector 800x480
• PiFi DAC+ v2.0

I did a fresh installation of ORAM 2405, and update.
After boot screen with Zynthian ERROR this is what the screen shows:

[ 1.728112] systemd[1]: failed to start backlight.service - Turn on/off Display Backlight.
Debian GNU/Linux 12 zynthian tty1

System reboots in a loop.

Do you have any suggestions?

You have to configure audio and display from webconf. Please, note that autodetection only work for well know hardware configurations, aka official kits.

You have to configure audio and display from webconf

I did it because I read your suggestion in previous posts:

audio: Hifiberry Dac+ (I believe it is ok)
screen: I tried MPI DSI 800x480, MPI5008 800x480 and custom device adding 800x480 and Framebuffer: /dev/fb1 but … the result is still ERROR

Maybe it can be fixed if I can “Turn on/off Display Backlight” as written on screen
but I have no idea about how to do it

I verified that installing Ubuntu 24.04 LTS on this HW the LCD works perfectly.

Hi @piattica !

If you see the error in the zynthian screen, then the display is working mate! :wink:
The problem is not the display. Please, send the UI logs.

And be careful with your fingers if you touch the Pi5:

Temperature: 70.8ºC

:sweat_smile:

you are right :slight_smile:

Hi @piattica the error you get comes from a bad audio config => jackd won’t start => zynthian-ui won’t start => ERROR message

This could be jackd parameter hw:0 meaning “hey jack, use the first audio device in the list” but the way devices (these could be also USB midi gears) are listed may change. Eg. Starting Zynthian with all USB devices already pluged in or first start Zynthian and then plug the different USB devices

Using ssh or webconf built in terminal type

aplay -l

This will give you the name of the device (“sndrpihifiberry” I guess). Then change hw:0 to hw:device_name and reboot.

If it doesn’t solve your issue, maybe “HifiBerryDAC+” isn’t the the good one

problem of restart loop was solved with your help thanks when I changed setting audio to HIFIBerry DAC+ light

9

but when I play, on mixer screen volume bars move but no sound from output.

If I type aplay - l:
root@zynthian://zynthian# aplay -l this is the result:

root@zynthian://zynthian# aplay -l

Check the audio levels view that output level is up. Does the main mixbus meter show audio level or just the channel strips? Have you checked the audio connection is good and actually making audio in your amp, e.g. touch the jacks and hear the hum?

11

Hmmmm …
I wonder if it half works because pcm5102a driver is loaded but this PiFi dac use pcm5122 (wich has, I think so, some software controls through I2C).

12

you are right

so what I can do?
Is there some audio option that uses pcm5122 ?

13

I’ll be back home soon and will be more confortable to investigate.

no you have to use HIFIBerry Dac+ : that one has pcm5122 on board, while HIFIBerry Dac Light has pcm5102

15

This audio card used to work with Stable 2401 os

16

so, how is it going with ORAM now ?

17

With ORAM no way to have the card working;
neither a USB card I tried to install, works

18

Even with HifiberryDac+ selected as audio device
and hw:sndrpihifiberry in jackd parameters ?

19

If I set as Hifiberry DAC+ I have a starting loop
