Re: Which Pi for a beginner?

While purchasing the latest and greatest model is not terrible advice, I might suggest you get the 3B+ model, since the OS and firmware is still being optimised for the Pi4, and the 3B+ uses standard HDMI (vs micro HDMI). The 4B is certainly a better value, since it's the same price, but features l...

*** Notice: Removal of old Raspberry Pi 'theme' from forum***

Hello all! Sometime this week we will be removing the `raspberry_pi` theme from the forum. This was deprecated a couple of years ago, and now has very few users (43!), and is effectively unsupported. All users using this theme will have it changed to the `rpi` theme. I've been using this one for yea...

Re: Raspberry Pi 4 usb boot?

You clearly do not realise how complex it actually is to do this. Requires an entire open source (not GPL) USB 2/3stack to be found/developed, to cope with whatever can be plugged in. Plus a USB HW driver that works via the PCIe interface, so PCIe also needs to work. Sounds like a lot to stuff into...

Re: Raspberry Pi 4 usb boot?

They released early so that manufacturers could get a head start, & that's likely the reason the 4GB version was in short supply. (A certain manufacturer of thin clients had a supply). This RPi4 version wasn't really due to be released until 2020, & I'm guessing that is why so much of the software ...

I would always start on the best you can afford, then work down to lower specced models if you have the need for something less powerful.

Its weird that unplugging replugging seem to fix the problem as the device does not support hotplugging.

Never seen anything like that! Will ask round the office. It's really bizarre. Have you tried a newly imaged NEW SD card? If you boot to console, does that go wrong?

Same suggestion - ask Canonical. Ubuntu is their distro, it's their job to support it. We have our own distro, Raspbian, which we are happy to support. I think that's a little disingenious Jamesh.

Re: Very magenta picture from NOiR camera when only light source is infrared

Ohh maybe that's the issue. I am using raspiVID not the raspiSTILL as described in your sticky post, would that be the issue? More specific, I'm outputting raspivid to VLC and streaming it in as an rtsp stream AWB is the same for vid and stills, so you still need the appropriate runes for greyworld.
