Razberry V1

Hello all,

Since my sd-card (Pi 2B) went corrupt (read-only) I decided to go for a fresh install of Pi OS AND domoticz on a new Pi 4.
After some troubles getting a working DB-backup from the broken SD-Card -but manneged to do so- I thought everything was ready to come back online.
Unfortunatly I can't seem to get the Razberry V1 daughter card working.
I followed this instruction: http://www.tangkau-ict.nl/index.php/nl/ ... moticz-pdf
This nodes-list stayed empty. After a couple of reboots and retries I got the nodes showing up, but all with ID 0x0000 and Type 0x0000.
An extra reboot resulted in an empty list again.

I guess the configuration has to be a bit different for the pi4, or I'm missing some sort of drivers for the Razberry V1 card.
Anyone any suggestions?

I found the problem... the console output is set to serial by default.
The "console output" to serial is configured in /boot/cmdline.txt with the entry "console=serial0,115200", which we need to get rid of, but still make sure that there is no "enable_uart=0" in /boot/config.txt.

In this example the V2 board is used, but it works like a charm for the V1 board I'm using.
