Zynthian doesn't boot anymore

Using Zynthian
1

Hi!
Since today my Zynthian doesn’t boot anymore. After switching on, I only see the linux console login screen.
I connected by SSH and tried to start zynthian manually This is was happened:

(venv) root@zynthian:~# zynthian.sh

This repeats until I cancel with CTRL-C

Any ideas except re-flashing the sd-card?

Jack is not running. What jackd configuration do you have? What hardware? What soundcard?

3

Form logs, it seems a V5.
Please, send a short from the webconf Dashboard, to verify the config.
Also, please run this command and send the output:

I2cdetect -y 1

Regards

yes, it’s a brandnew V5.1. Worked without issues until today.

(venv) root@zynthian:~# i2cdetect -y 1

Webconf dashboard is not possible, because the webserver is also not running

I flashed a new sd card. Now it works again. Let’s hope that was a one-time thing…

Hi!

This is weird…
Yesterday night, I didn’t switched off my box. And now I’m coming home and all I see is the login console…
And when I try to run zynthian.sh on the console, there is exactly the same issue than before I flashed a new SD card.
What’s going on???

It’s really weird. Did you copy the file by hand?

You can run this command:

update_zynthia._sys.sh

It should restored the config .

If the problem keeps reproducing, please consider buying a new SD-card.

Did you copy the file by hand?
Which file do you mean? I didn’t copy anything by hand.

You can run this command:

update_zynthia._sys.sh

It should restored the config .

(venv) root@zynthian:~# update_zynthian_sys.sh
