Expansion Board details

To use an alternative config, change freedom-u-sdk/Makefile as follows:
linux_defconfig := $(confdir)/linux_framebuffer_smp # for example

Hey @AndrewBack, @bruce,

Here are the cards we’re using with the HiFive Unleashed & Unleashed Expansion board at the office. They’re obviously not the only cards that work, just a pair that worked out of the box. My co-worker David Lee acquired these boards and when asked, he said he just went to Fry’s and bought a few cards that looked decent yet reasonably inexpensive.

This is the video board: DIAMOND Radeon HD 6450 w/ 1Gb of RAM

Here’s the USB board: about as generic as you can get

And I’m willing to bet you could figure this out by looking at the boards and the sockets on the expansion board, but for completeness sake, here’s the USB board & the Video board seated in their sockets:

And here’s the output of the lspci:

And the output text is:

@mhamrick, @terpstra, many thanks! HD 7450 ordered.


@terpstra: So we have M.2 SSD & SATA ports enabled by default as well apart from PCIe pins. Do I have to do configure something else or I just connect SATA HDD/NVME SSD and it works magically ?

(Wesley W. Terpstra) #25

If you have the kernel drivers compiled in, M.2 worked for me immediately, as did SATA.


Awesome. Thanks @terpstra.
