Re: [Not getting my full Gigabit internet speed on RPI 4b 4GB]

Can you describe the network infrastructure your RPi is being connected to? It would be unusual for most users outside of institutional or commercial settings to get full Gigabit Ethernet speeds to or from sites on the global Internet. Sorry for the late response the pi is directly connected to my ...

AFAIK NOOBS it's not supported on the RPI 4
NOOBS is supported on the Pi4, but IMO it's just easier to use Raspbian.

So, do you get a rainbow screen, then it goes black?

Re: Compute Module 4

Perhaps if enough people here say they want one, that will encourage them to make one. They already know that people want a CM4 so threads like this aren't very productive.

Re: stuck in wifi - Debian wheezy

Dougie is right, Wheezy is very old, we are currently two entire OS releases newer. Try a new SD card with a fresh install of Buster, if that still goes wrong, then we can look at it.

Re: How to watch a stream in SRT protocol with Pi4

At the moment, the only software which uses the H265 (HEVC) decoder on the Pi 4 is LibreElec (which uses Kodi). I am sure that supports streaming, but I don't know how you set it up. I'd suggest getting an install on LibreElec going and having a google on how to set it up for receiving streams.

Re: Display not displaying my raspberry PI

Use the edid-decode app built from the above commands to decode the EDID you dumped.

Working from memory on how these things work.

tvservice -d fred.bin
edid-decode fred.bin

and cut and paste the reply here.

Re: Farnell sells RPi4s with LPDDR4-2400?

This appears to be a typo on the Farnell website, 3200 is the correct speed. I've forwarded this to marketing/sales to get fixed. All Pi4's (Farnell, RS) come off the same production line (used by Farnell or RS with their own supply chain), and should be identical. Different memory speed needs diffe...

Re: Display not displaying my raspberry PI

Looks like you need the detailed timings patch, currently being code reviewed here. But that;s aimed at the Pi4 so I would need to push it to the Pi3 firmware branch as well. Hmm. I'll have a think. So what I think is happening, the display is 1366x768p60 which is a non-standard resolution, so the t...

Re: A modest (passive) suggestion

It's a nice idea (and passed on), but not going to happen on the Pi4 for routing reasons, as mentioned above. The current board was a nightmare to route as it is, adding a couple of extra through pins would make the nightmare even more nightmarish.

Re: trying to buy more than 1 pi zero

Interestingly, you can go to any Micro Center in the States and buy as many Pi Zero computers as you need at a time with increased per-unit pricing. That's the most bizarre pricing I have seen, for a Pi Zero W - 1 at $5.00 each 2-5 at $14.99 each 6+ at $19.99 each https://www.microcenter.com/produc...
