Re: CM4 Mass Programming

Actually reading about the protocol, it seems the start of transfer would have to be synchronised with UFTP, so this wouldn't actually help (and will in fact make it worse since all the units would finish at the same time wasting the operators time... So yes we'd probably have to implement our own v...

Re: CM4 Mass Programming

It sounds like UFTP does everything you suggest (i.e. allows individual nodes to request retransmissions), don't know about whether it'll allow a device to enter the stream at a random point, but that doesn't sound particularly difficult to implement...

Re: STICKY: libcamera - open source camera stack

I haven't tried it, but considering there are overlays for each of the things you ask that suggests the drivers are all there, it just requires you manipulating the device tree sufficiently to enable the functionality you require.

What is the display? Do you have a specification? Does it have a driver in the Linux kernel already?

Re: Microsoft GPG key suggestion

Ok this topic isn't really a topic anymore so I'm locking it... We are no longer checking the Microsoft repo for changes because code is now hosted in the Raspberry Pi repo. I realise many of you don't like this, but that's the solution we went for after much deliberation.

It seems pretty clear that there is some sort of legal arrangement between the two companies. And that nobody (on the inside at either company) wants to talk about it in public. I think we need to leave it at that. Even if I said there wasn't (which there isn't) you'd not believe me anyway, since y...

Software licensing (this is one I get asked a lot!): The Raspberry Pi OS distribution is covered by lots of different licenses, but before re-distributing it the only things you need to remove are RealVNC and Wolfram Mathematica which are non-redistributable.
