widget_mode=3 (sniffer) ignored on Raspberry Pi Zero?

[sdbbs]

Hi,

I have a setup with:

• Raspberry Pi 3B+ running Raspbian Stretch, with OLA built from git
• RDM isolated board with USB (FT245RL), driven by a Raspberry Pi Zero, and connected to the Rpi 3B+ over USB

The SD card on the Raspberry Pi Zero, has been previously formatted for Raspbian (so it still shows "RECOVERY" and "boot" partitions); I have simply extracted the files in the zip linked on 4. Orange Pi Zero / Raspberry Pi : DMX USB Pro, the Raspberry Pi SDCard zip-file, to the "boot" partition. Then I added a file params.txt manually on the boot partition, with contents as on http://www.orangepi-dmx.org/raspberry-pi-rdm-controller/configuration - except with widget_mode=2.

When I boot this system, and attach a HDMI monitor/display to the RPi Zero, I get this written on screen:

[V2.3] Pi 3 Model B+ 1GB Compiled on Oct 5 2019 at 12:27:44
RDM Controller with USB [Compatible with Enttec USB Pro protocol], Widget mode : 2 (RDM)
Device UUID : 5000:eb500653, Label : Raspberry Pi DMX USB Pro

However, if I then power off the system, and replace widget_mode=2 in params.txt on "boot" partition of the SD card with widget_mode=3, then insert the SD card in the RPi Zero and boot again - then again I get exactly the same screen text as above, that is "Widget mode : 2 (RDM)", which means the widget_mode=3 was ignored.

Where have I gone wrong in setting up this system? And what can I do, do get the widget in Widget Mode 3 (RDM Sniffer)?

Hi sdbbs,

All files should be in the root directory of the FAT formatted partition. Please make that there is no # before widget_mode=3

That's not an Zero, but a Model 3 instead.

Please note that the preferred ARM board is the Orange Pi Zero LTS 256MB -> https://github.com/vanvught/rpidmx512-zip/issues/6#issuecomment-640098142

When you have an Orange Pi Zero LTS 256MB, then it would be interesting to know how the RDM discovery is going when using the Art-Net firmware. With this configuration, the discovery process is completely done in the Zero firmware and the result is then send to OLA.

Thanks, Arjan
