IOT2050 WITH NODE RED VERSION 3 AND NODE JS VERSION - PROBLEM WITH READING GPIO PINS

[aviranp]

Hello ,

I have IOT2050 FS:05 WITH NODE RED VERSION 3 AND NODE JS VERSION 20.7 .
WORKS FINE BUT WHEN I AM TRYING TO READ GPIO PINOUT USING NODE RED INTEL GPIO NODE.

I HAVE A A LOTS OF PROBLEMS ;

1. I CANT INSTALL IT.
2. THE NODE ONLY SUPPORT NODE JS VERSION 12. WHEN NODE RED 3 NEED MINIMUM 16.X VERSION OF NODE JS....

IF I CANT READ THE PINS I CANT WRITE ANY PROGRAM UNLESS I AM USING SIEMENS PLC. ( WORKED FINE) .
ANY CLUE ??

THANKS

Compile the image from the master branch (or use the output of a recent CI run), and you will get Debian 12 with NodeJS 18 with a working GPIO node.

Installing your own NodeJS version into a custom image implies that you have to take care of recompiling mraa, the foundation of node-red-node-intel-gpio, for that NodeJS yourself. Possible but not a beginner's task.

Hey again,

I want to compile the image but as I understood there is still a problem with the ethernet cards that they are not recognized by the Debian system? was it fixed?

thanks,

Ethernet on PG1 needs some patches here, PG2, M.2 etc are fine already. For PG1, we are waiting for more feedback on https://lore.kernel.org/netdev/20231219174548.3481-1-diogo.ivo@siemens.com/.
