... but I think you can use it with just the portenta, (not fully sure). Anyone having any success with it?
I could run a minimal MicroPython Script on the Portenta (the hardware HelloWorld) according to the OpenMV Tutorial. But I can't start the Script without the OpenMV IDE.
When you are connected via OpenMV, you have mounted the "filesystem" from the Portenta. But it is without any structure. There is only the root directory available, not things like /flash etc.
On the pyboard, there is a boot.py script, then you can copy your main.py script on the drive. I expected this base structure:
and the I would upload my main.py:
After booting, the boot.py script is executed and then your main script is started.
How exactly runs MicroPython on the Portenta?
If needed, where can I find the boot.py?
Is there also a /flash directory needed or can one copy this files on root?
Does Arduino officially support MicroPython on the Portenta?
In my mind, the Arduino Portenta story is a bit handcraft and it makes not really a professional impression. Let us wait for better times ;-)
