News Raspberry Pi 4 Modded to Work with Multiple PCIe Devices

[Admin]

Colin 'Domipheus' Riley said he successfully made a Raspberry Pi 4 detect USB accessories, a SATA controller and some GPUs via PCIe.

Kinda makes you wonder what kind of success or new projects a Raspberry Pi type board would do if you had multiple native 16x PCIe slots in an mATX package. Or even full size atx.

So, you want an ARM-based PC, huh? Maybe something like this?

Developerbox (Socionext)

SynQuacer™ E-Series is a software development environment compliant with Linaro’s 96Boards open hardware specification. This has been built jointly by Socionext Inc., Linaro and GIGABYTE. It contains one “SC2A11”

I should quickly add that it uses the same type of ARM cores as Pi v3. So, in spite of the core count, it's no match for most modern x86 CPUs.

BTW, the article doesn't say this, but he enabled the additional slots through the use of a PCIe switch. However, the connection to the Pi is still probably connected by a single lane (and I'm guessing PCIe 2.0, at best).

Here's the blog entry, since I didn't notice a "source" link, in the article:

Raspberry Pi 4 PCI Express: It actually works! USB3, SATA… GPUs?

Recently, Tomasz Mloduchowski posted a popular article on his blog detailing the steps he undertook to get access to the hidden PCIe interface of Raspberry Pi 4: the first Raspberry Pi to include PCIe in its design. After seeing his post, and realizing I was meaning to go buy a Raspberry Pi 4...
