Many users also complained that the Pi 4 is not working with all USB-C cables.
If you've purchased a Pi 4, you'll want to get a different USB-C charger, the cheaper, non-e-marked kind that ships with smartphones.
Given that USB-C is a complicated connector, some cables are electronically marked, which means that they have an integrated chip to support a wide range of devices. Raspberry Pi 4 owners will need to use non-e-marked USB-C cables.
There's a very good chance you aren't using an electronically marked (e-marked) cable at all.
A guide to Raspberry Pi in 60 seconds The potential of this fully functional, ridiculously low-priced little computer is limited only by your imagination. But there's a problem: The USB-C charging doesn't work with some USB-C chargers.
Eben Upton, founder of the Raspberry Pi Foundation, has confirmed this is a problem with the Pi 4 and it will limit which cables can provide power for the single board computer. But buyers only needed a few weeks to discover their brand new mini-computers pack a serious USB-C issue that could render them useless, at least until you figure out what's wrong.
The Raspberry Pi 4 is better than its predecessor in every way. He explains that from a technical perspective, the USB-C specification defines two pins called CC1 and CC2 for connecting to the power sink in a specific way.
However, it's come to light that the Pi 4 doesn't work with certain USB-C cables due to a non-compliant USB-C charging port.
"It's surprising this didn't show up in our (quite extensive) field testing program", Upton said. Incidentally, the new iteration does not have a dedicated power supply port and has to completely depend on USB Type C port. One of the most significant moves is the switch to USB-C for power, but it turns out that this port has a rather interesting issue. Or no longer it's a long way rarely any longer a calamity, then - that that you must factual have to be conscious out must you are going to make dispute of a Pi 4 because the center of your subsequent DIY venture.
Alternatively, you can sit tight and wait for a future board revision which will rectify this issue. As a result, the cable doesn't supply power, and your Raspberry Pi won't start up.
