2020 mode on the Raspberry Pi 5

[Mooneer Salem]

Hi all,

I finally managed to get the Raspberry Pi 5 that I preordered a few months ago. Unlike with the 4, it appears that we're finally able to handle 2020 mode (see attached photo of TV screen showing htop running while decoding the sample 2020 file). The audio also sounded as expected, albeit at pretty low volume.

Anyway, now to get the special USB-C power supply for it since it doesn't like even the ~100W laptop supply I tried to use all that much. :)

Thanks,

Wow, very nice there Mooneer, and great progress on that.

The 27W raspberry pi 5 power supply is specifically coded to be able to deliver 5.1V at 5A, as well as running higher voltages at lower currents if permitted by devices.

Elsewhere it has been reported that due to a firmware bug, other 5A capable power sources even when used with a 5A e-marked cable, fallback to 5V 3A equivalent to running a pi 4 power supply.

Being the 27W bricks are available and cost 12-13 USD as well as being backwards compatible with a pi 4, there’s good reason to upgrade.

The main functional difference between the two is getting 1.6A per port maximum USB device current up to power limits as opposed to 0.6A per port.

Also, possibly of interest. I’ve managed to get the PCIe interface on the pi 5 to recognize PCIe and PCI (thought a bridge) devices other than nVME drives. I specifically wanted to be able to run IEEE-488 GPIB interfaces for test equipment.
