Hello, I finally updated to V1.19 I used the port GPIO 22 to receive/send a signal to a power board that cuts cleanly the power after the pi has shutdown
Since upgrade to V1.19l, I can't write in /sys/class/gpio/export any more : tc@piCorePlayer:~$ echo "22" > /sys/class/gpio/export sh: write error: Device or resource busy But I can't see any process locking that file, and the file is empty: tc@piCorePlayer:~$ sudo lsof /var/lib/dpkg/lock |grep export tc@piCorePlayer:~$ Any idea why? Thanks in advance!
