Uploading programs to Portenta C33 using Ethernet OTA

Hardware Portenta Portenta C33
1

I am interested in using an Arduino MCU in an industrial network application. The network is not connected to the internet so I can’t use the cloud IDE but is all on Ethernet. I am interested in the Portenta C33 as it has 2 CAN interfaces that would be useful to my application and the high density connectors. Does anyone know if it is possible to upload programs to the MCU over Ethernet? I have found a GitHub library called Arduino OTA but it doesn’t look like it works for Portenta boards. If anyone knows of a way of doing this, I would be very grateful. Uploading directly from Arduino IDE or to a HTTP server (like ESP8266/32) is good. SD card and QSPI is not possible as I only have Ethernet interface. Many thanks for any help!

EDIT: looks like the example is not would it should be. C33 SFU OTAUsage example just blinks LEDs? · Issue #152 · arduino/ArduinoCore-renesas · GitHub

but this one may be useful

example of the download is here in the OTA for Uno R4

Hi,

Were you able to make this work? I'm interested in the same thing (via WiFi but the file download part should be the same)
