[REPORT] OpenWrt on Barracuda F180b

[NC1]

Some time ago, I started a thread about Barracuda F180:

[SOLVED] Barracuda F180: stumped by a switch

I am having fun with yet another dangerous fish. This time, it's Barracuda F180. Here's an artist's rendering of the device's rear: [image] Visually, it's easy to distinguish a group of four ports (labeled 1-4), then a group of two ports (5-6), and finally, a group of eight ports (S1-S8). My working assumption is that the S denotes an internal switch. Here are some (hopefully relevant) listings edited for brevity and readability: root@OpenWrt:~# ls -l /sys/class/net br-lan -> ../../…

That was about Barracuda F180a; now I have my hands on a Barracuda F180b, and it’s a total and complete redo (I believe Barracuda actually switched hardware manufacturers). Here’s an artist’s impression of the device’s business end:

Let’s get the obvious out of the way first. Count them, 16 Gigabit ports: 12 RJ-45 (Intel i211) and four SFP (Intel i350). I suspect there’s some switching witchery going on behind the scenes. Take a look at the lspci output:

It looks like there’s some switching hardware lurking in the background. Wondering to what extent, if any, it’s usable with OpenWrt…

Now, back to regular programming.

The device runs on an AMD RX-216TD processor (dual-core, 1.6 GHz base, 3.0 GHz turbo) with 8 GB RAM and an 80 GB SATA SSD. Here’s a view of the internals:

The stock wireless card is Qualcomm Atheros AR93xx (an ath9k / Wireless-N device), but the slot it sits in (bottom left corner of the photo above) is full-size, so the card is upgradable at least to AC. (Actually, come to think of it, AsiaRF makes AX cards in the mSATA form factor, and they are probably not alone…)

BIOS has a factory password, but it’s the long-known Barracuda standby (bcndk1). The default console speed is 19200 bps. I changed it to 115200 to match OpenWrt’s default.

OpenWrt installation is completely unproblematic, as long as you remember to use UEFI firmware (I tried both ext4 and squashfs options). You can either take the SSD out, write OpenWrt onto it, and plant it back, or boot from a USB stick, download OpenWrt image, and expand it onto the SSD. It looks like the device is hard-coded for UEFI-only operation; I didn’t find a way to switch to legacy boot in BIOS.

Port detection order is straightforward; port 1 is designated eth0, port 2, eth1, and so on, all the way up to 16 / eth15.

The stock power supply is 12 V / 7.5 A with a 5.5 mm barrel connector.

This appears to be a capable device; I am intrigued by what looks to be switching hardware…

Those are PCIe switches (not network switches) which are necessary to accommodate all the Intel PCI Ethernet devices.

Ah, I see… Thank you for explaining!

Looks like there is space for a m.2 sata or nvme drive near the bottom of the board next to the wifi card. That could be quite useful to separate storage from the boot drive which should make upgrades much easier.
