Test Google Coral TPU M.2 Accelerator A+E key

I just bought a Coral M.2 Accelerator A+E key after seeing a lot of buzz about this little 'IoT' TensorFlow-compatible AI accelerator.

coral-tpu

I also just received an M.2 A key to PCIe 1x slot adapter card (see https://github.com/geerlingguy/raspberry-pi-pcie-devices/issues/38), and I will pop the Coral board into there.

I haven't done much with AI/ML, but apparently one of the big holdups for using this board with the Pi may be overcome soon—see: https://github.com/google-coral/edgetpu/issues/280

(And I don't want to step on @timonsku's toes here either—he was the original inspiration for me getting this particular card, after seeing his Piunora; just figured now is as good a time as ever to take a quick stab at TensorFlow.)

See related, in the Pi Forums: https://www.raspberrypi.org/forums/viewtopic.php?p=1772610&sid=4833ac3f714618282207affca2bcd846#p1772610

And the patch advertising MSI-X support in the Pi Kernel (currently only on 5.10.y branch): https://github.com/raspberrypi/linux/commit/6bf63f7711b550de8c803a4c4ad792ecfbe721df

(Note that it may be incorporated into Ubuntu for Pi too... https://twitter.com/m_wimpress/status/1345077692568367105

I'd maybe recommend following as per description from your first linked datasheet, in section 5.3, possibly a dear to both lower and upper cooling of the TPU to provide maximum performance, especially considering you're wanting to run 24/7, also take special note to possible transient spikes in power up to 3A

Add Seaberry Mini ITX Motherboard with tons of PCIe connectivity

The Seaberry Pi CM4 Carrier Board is a Mini ITX form factor motherboard for the Pi with tons of PCI Express slots (including M.2 M-key for NVMe, A/E-key for WiFi/Google Coral TPUs, Mini PCIe, x16 PCIe, x1 PCIe... need I go on? It also has a number of other interesting IO and features built-in to make it a very full-featured motherboard for a Pi-based PC!

It should be a typical 12v 2.5mm barrel plug; I powered mine with this adapter: https://amzn.to/3y4wPBm

For the PoE, a standard HAT wouldn't work since the PoE pins are separated from the main GPIO header (unlike the CM4 IO board layout)—you need a separate type of PoE device that you can break out and add jumpers to get to the PoE header on the Seaberry. ALFTEL sent one to me that can do bt, though I haven't had a chance to hook it up and test it yet (and my main switch only does PoE+ and not ++, so I'd have to get out an extra ++ injector too!).

Regarding PoE, has anyone figured out how to get it to work? It says it's poe capable, and I have two PoE switches but they don't power on the board. I also have some LoveRPi poe hats but they don't fit on the board, nor do I think they would support 802.3bt. So I am a bit anxious as to whether or not I should take some cables to connect the pins to see what would happen.

Also what size is the barrel? The ones I use for my quartz/rockpro64's don't work.

Test Radxa Taco 5x SATA NAS with 2.5G and 1G Ethernet

See original issue: https://github.com/geerlingguy/raspberry-pi-pcie-devices/issues/202

DSC03256 (1)

I have a Taco (well, the Penta main board that goes inside) and would like to do some testing on it; run some benchmarks, test compiling ZFS, etc.

Things to test:

  • Power consumption (at wall, using Kill-A-Watt) at idle with 5 SATA drives + NVMe, and running benches over network
  • Network performance (single port, 2.5G)
  • NVMe performance (single drive)
  • SATA performance (single drive)
  • SATA performance (5-drive RAID0)
  • SATA performance (5-drive RAID5)
  • SATA performance (5-drive ZFS RAIDZ1)

@vebmaster - The one I used in the video was provided by Radxa; it should hopefully be available soon on their website.

Thx. Where did you buy the Radxa Taco board and for how much?

Add Radxa Taco - the successor of the ROCK Pi SATA HAT(Penta SATA CM4 carrier board)

I've been following this repository for quite long time. As a Raspberry Pi fan, we've been working on the Radxa Taco for a while, which is an ultimate CM4 carrier board designed for nas/server/router applications. The ideas is based on the Quad SATA HAT for the Raspberry Pi 4 and go further beyond it. The Radxa Taco has the following features:

  • Use asm1806 pcie switch
  • Dual ethernet, one 1000M from CM4, one 2.5G rtk8125b to pcie switch
  • 5x SATA via JMB585 to pcie switch
  • 1x M.2 M key NVMe to pcie switch
  • 1x PCIe M.2 WiFi module, support Intel AX200
  • 10P header for Top Board with OLED and button
  • RTC/USB 2/uSD card

The case is working on...

The Radxa CM3 RK3566 PCIe support:

  • Support MSI with Per-Vector Masking (PVM) and 32 multiple MSI
  • Support MSI-X with Per-Vector Masking (PVM) and 64 MSI-X table size

Test 52Pi CM4 Router Board

I should be getting a 52Pi CM4 Router Board soon—no rush on the testing, but I would like to see how it compares (especially with things like pps) against the DFRobot and Seeed Studios boards.
