Naomi Pi 'WiPi Netbooter' - compatible with Pi 3&4

[coll83]

Hi all.
Anyone know why im getting this?
Keep getting a error message when I try and log on to netbooter.local

Err_connection_refused

It was connecting..

Any advise on what to make a power cable with for USBC on the RPI4B? I just pulled apart a usba to usbc power cable and the wires are pretty thin, looks like max amperage on usba is 3.1amps. Is it better to just use GPIO?

Few questions here.
Openjvs is integrated. Is the integration for this project compatible with the openjvs pihat?
Can I still use a USB485 converter with this pi image?

Are you asking if wipi netbooter with openjvs works with the openjvs hat? Yes, it does. Set up is explained in the manual.

And I believe usb rs-485 should work, and you'll want to make sure yours has a ftdi chip. Haven't tested it myself, but people have made their own adapters

Both YES - While the manual refers more to the hat the USB485 is working just fine (using it myself)

Is there any reason you need more than 3.5A for a RPI4B? That should be plenty unless you are running so power hungry hats. At idle the 4B draws 0.51A (2.5W) under load maximum draw is 1.52A or 7.6W at 5V. The CN12 connector (or is it CN2 I forget) draws off the 5v rail so it should be fine. I looked at this when creating this to run my set-up. Should have spares available in a week or so if anyone is interested.
