Re: Encrypted Partition on eMMC via TPM?

What is it that you are trying to do/protect? Maybe what you want is a private key in the TPM which is global across all your devices, and you put the public key into your code such that you can prove (signature check) that the TPM cannot be MIM attacked when it hands you an encrypted AES key. Using...

Re: CM3 boot issue

When you say 'on Linux' is this on a Raspberry Pi computer? It would be good just to check whether this is a problem with the CM3 or the software on the host?

Re: CM3 boot issue

Can you confirm the numbers here, is this two out of two or two out of a thousand? 1) Have you tried using a high quality USB cable, sometimes the USB signals can trigger problems with some devices. 2) Have you tried running rpiboot on a Raspberry Pi instead of using an x86 PC. (I'm assuming here) 3...

Re: USB Vendor ID/Product ID

If anyone has a suitable suggestion as to how this would work, I'm happy to hear it. But I think this will only work for Linux drivers which are upstreamed.

Re: Using a Raspberry Pi to flash Windows 10 to a SD card

Yes it is perfectly legal to use the Windows On Raspberry to install the available ARM64 bit image (which you download from Microsoft's servers). Once you do that it will give you an evaluation version of the software and nag you to activate a license (i.e. pay for it). What isn't legal is downloadi...

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.

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.
