Hi,
I try to setup the hilschernetpi/netpi-desktop-hdmi on a supported NIOT-E-TPI51-EN-RE.
I try it with NIOT FW 1.2.0 and the container work fine just for a while, then the NIOT slow down after a few hours and was unreachable.
So I update the FW to 1.2.1.0 and the container seem to run ok on the docker but nothing shown on HDMI screen
Any suggestions?

Well first of all containers works the same independent of the OS version that is running of on the device. This is exactly one of the biggest advantages of a container ... running always the same independent of any OS...
What is most important for a Raspberry Pi graphics controller to enable HDMI signal is to have a monitor/display already connected at the time the NIOT-E-TPI51-EN-RE device was powered. If no monitor was connected during the power up time then HDMI output will never work. This is a restriction of the graphics controller.
So are you sure you have connected a monitor during power up times?
Thx

One more question in order to clarify whether or not your device/graphics contoller works correctly.
If you say you have a monitor connected ... do you see boot messages on the monitor after you powered the device? Or is it a black screen from the beginning?
Also very important is whether or not you are using a HMDI to HMDI cable 1:1 or a HDMI to DVI cable maybe. Cause this could be also a problem that your screen remains a black screen.

Ok but if you want to run Node-RED so why do you install then the desktop container?
Instead you should install a Node-RED container or? We are offering a Node-RED example container since years:
https://hub.docker.com/r/hilschernetpi/netpi-nodered
After the proper installation then you can reach Node-RED on netPI via the ip address at port 1880.
If you want to cun a custom C-Code on netPI also then you need to compile it or? So you need a compiler and a base image to compile it. For this we have a Raspbian OS container also:
https://hub.docker.com/r/hilschernetpi/netpi-raspbian . Running this container feeds your netPI with all the functions users of a normal Raspberry Pi are use to. So you can login to this Raspbian container via SSH as usual via a console shell and transmit your code and then compile an run it.
This is how I would do it.
Thx
