Keypad no work

Hello how are you ?

I hope that I am not mistaken for a forum, I am in France and it is impossible for me to find a forum for mutual assistance. I nevertheless managed to do the circuits to solder and mount my phone.

​

However I have a problem with my delta-B zero phone. it starts well I have the screen which displays the menu correctly,

but the problem I can only use the keyboard once and then it no longer reads the keys. With you a solution?

​

Thank you

Does resetting the arduino make it work again?

Hello, thank you for the response.

So once launched pressing the reset button on the arduino does not change anything I have to restart the phone completely by disconnecting the battery.

I checked using the arduino programmer it reboots well when pressing the reset.

It narrows it down a bit. Can you SSH into the phone from a computer? Does the entire system crash when it fails?

If the system stays up, try looking at the systemd logs for the hardware services: https://wiki.zerophone.org/index.php/Software#ZeroPhone_low-level_API

The service logs may show an error, or you could try restarting it and see if it restores keypad interaction.

I don't know the exact service, but look for it in the listing with a command like 

systemctl --type=service

Or possibly 

service --status-all
