DietPi does not find modul at gpio

[AnBad]

Hello,

I have hooked up a Modul (EnOcean Pi 868 Gateway (TCM 310 odr TCM_ESP3_0)) at the GPIO, but dietpi will not find it.

What is wrong?

The code

Code: Select all

ls -l /dev/ttyAMA0

should result in:

crw-rw---- 1 root dialout 204, 64 Jun 7 22:56 /dev/ttyAMA0

but only gives this:

ls: cannot access '/dev/ttyAMA0': No such file or directory

and

Code: Select all

ls -l /dev/serial*

should result in this:

lrwxrwxrwx 1 root root 7 Jun 8 18:30 /dev/serial0 -> ttyAMA0

but only gives that back:

ls: cannot access '/dev/serial*': No such file or directory

I guess a libery is missing or some small tweak has to be changed?

Can anybody help me.

The modul is used to transmit enocean homematic protocolls.

Many thanks.

You need to enable the serial console via:
dietpi-config > Advanced Options > Serial console

I am using a Raspberry 4 with deCONZ RaspBee II having the same issue.

/dev/ttyAMA0 seems not bo be configured correcly giving:

Code: Select all

crw-rw---- 1 root dialout 204, 64 Jun 7 22:56 /dev/ttyAMA0

but giving:

Code: Select all

crw--w---- 1 root tty  204, 64 Okt  8 00:12 /dev/ttyAMA0

I ave enabled ttyAMA0 in the settings, but that has no effect too.

It works on Raspberry3 with Raspian.

You need to disable the serial console on ttyAMA0 to make it usable for RaspBee. A serial console means there is a login getty waiting for interactive user login via attached serial terminal. In your case you want the port but no login console on it. This also explains why it has tty group permissions .

Also assure that Bluetooth is disabled since ttyAMA0 is by default used by Bluetooth on all onboard-WiFi RPi models.
