The Raspberry Pi 4 Has a Flawed USB-C Port

Raspberry Pi 4 won’t work with some USB-C power cables Raspberry Pi 4 Won't Work with Some USB Type-C Cables

The unfortunate result is that the Raspberry Pi 4 won't work with just any USB-C cable.

E-marking is a technique which gives a cable a digital signature based on what the cable is going to do.

"A smart charger with an e-marked cable will incorrectly identify the Raspberry Pi 4 as an audio adapter accessory and refuse to provide power", says Upton.

The bad news is that there's not a lot the team can do about this until the next hardware revision - the quirk is built into the hardware. The Raspberry Pi Foundation will probably fix this design error in future board revisions, so you might get a more compatible device if you wait for that.

"It's surprising this didn't show up in our (quite extensive) field testing program", Upton said.

Ward recommends that Raspberry Pi 4 owners use non e-marked cables for now, such as those used by many smartphone chargers. It features a powerful 1.5 GHz quad-core 64-bit ARM Cortex-A72 CPU, up to 4GB of RAM, support for up to 4K resolutions, Bluetooth 5.0, Gigabit Ethernet, 2x USB 2 and 2x USB 3 ports, 2x micro-HDMI ports, and a USB-C power supply.

The new Joker Movie isn't based on the comic books at all
Far From Home's opening weekend now behind us, there remains one more major comic book movie to drop in 2019 - and that's Joker . The film evidently eschews much of the common backstory and numerous tropes fans associate with Joker's origin.

Instead of trying to come up with some clever circuit", Leung writes, "hardware designers should simply copy the figure from the USB-C Specexactly [emphasis his] The Figure 4-9 I posted above isn't simply a rough guideline of one way of making a USB-C receptacle.

The Raspberry Pi Foundation a couple of weeks back announced its latest single-board computer.

Perhaps the most notable change was the move to USB Type-C for power. It's actually normative, meaning mandatory, required by the spec in order to call your system a compliant USB-C power sink.

As an illustration, you should utilize a MacBook Pro charger with loads of USB-C devices. "The Raspberry Pi 4 is actually a pretty incredible little machine", said Offensive Security. E-marked cables are fully featured USB-C cables with chips inside that negotiate power management, accessory modes, data rates, and other communication specs. However, several modern-day chargers are able to deliver far more power owing to newer Fast Charging standards.

To get started, you can download the Raspberry Pi 4 image from Kali's website and following these instructions to get it setup.
