PN532 NFC HAT phoniebox-rfid-reader.service: Failed with result 'exit-code'.

[gsandreas]

Hi,

I'm Using an PN532 NFC HAT with I2C and I encounter the follwoing problem:

sudo systemctl status phoniebox-rfid-reader.service
● phoniebox-rfid-reader.service - Phoniebox RFID-Reader Service
Loaded: loaded (/etc/systemd/system/phoniebox-rfid-reader.service; enabled; vendor preset: enabled)
Active: failed (Result: exit-code) since Wed 2021-12-01 23:45:28 CET; 37s ago
Process: 1585 ExecStart=/home/pi/RPi-Jukebox-RFID/scripts/daemon_rfid_reader.py (code=exited, status=1/FAILURE)
Main PID: 1585 (code=exited, status=1/FAILURE)
CPU: 721ms

Dez 01 23:45:28 PhonieBoxSonja systemd[1]: phoniebox-rfid-reader.service: Scheduled restart job, restart counter is at 5.
Dez 01 23:45:28 PhonieBoxSonja systemd[1]: Stopped Phoniebox RFID-Reader Service.
Dez 01 23:45:28 PhonieBoxSonja systemd[1]: phoniebox-rfid-reader.service: Start request repeated too quickly.
Dez 01 23:45:28 PhonieBoxSonja systemd[1]: phoniebox-rfid-reader.service: Failed with result 'exit-code'.

It seem, that it tries to start the Service to fast, and then its been stopped during an restart counter overrun.

I can find the Device by using i2cdetect -y 1

sudo i2cdetect -y 1
0 1 2 3 4 5 6 7 8 9 a b c d e f

Edit: I'm using an I2C Sound card on 0x1a. UU shows that it has been found and loaded an Kernel driver.

Also by disconnecting the Soundcard, and then place the jumper onto RSTPDN<->D20, no difference ocoured. Can you please help me?

The failure states, tthat di eDaemon_RFID_Reader.py triggers a problem.

Manually startet the Phyton script, i tpromts that the Modul evdev is missing.

Traceback (most recent call last):

Is it installed?
