Adding support for Comfast CF-E313AC v2

immunizedelirium · May 31, 2025, 11:28pm

I'm working on porting OpenWrt to the Comfast CF-E313AC v2, which is superficially similar but internally different from the CF-E313AC. Posting here to solicit tips, pointers, criticism, etc on my first port and to document this device.

Hardware:

Atheros QCA9563-AL3A 800MHz
128MB RAM (Nanya NT5TU64M16HG-AC)
16MB SPI NOR (MXIC MX25L12833F M2I-10G)
QCA9886 2x2 5GHz 802.11ac
QCA8337-AL3C 1GbE Ethernet switch
RS706C watchdog
4 RSSI LEDs
1 WAN LED
1 LAN LED
1 WLAN LED
1 always-on power LED
Serial UART solder pads and unpopulated pins

Two options tested for installation:

Use the stock firmware's update page
Use the uboot firmware flashing webui:
a. Hold the reset button during boot
b. When the lights start flashing, continue holding for 8 seconds
c. Give your computer an IP address like 192.168.1.10
d. Open your browser to http://192.168.1.1
e. Use the form to select and upload your sysupgrade firmware file

TFTP flashing at boot is supported from 192.168.1.10.

The uboot console seemed to have keymap issues, so was not really tested.

Serial interface settings:
uboot output: 128000,8n1
linux: 115200,8n1
uboot console: 57600,7n1?

One thing I haven't yet been able to get working is the integrated QCA8337-AL3C switch. The stock firmware does this in 02_network:

        ucidef_set_interfaces_lan_wan "eth0.1" "eth0.2"
        ucidef_add_switch "switch0" "1" "1"
        ucidef_add_switch_vlan "switch0" "1" "0t 2"
        ucidef_add_switch_vlan "switch0" "2" "0t 1"

but when I try what seems like it should be the modern equivalent:

		ucidef_add_switch "switch0" \
			"0@eth0" "1:wan" "2:lan"

or

		ucidef_add_switch "switch0" \
			"0@eth0" "1:wan:2" "2:lan:1"

I get tagged traffic coming out the ports. I'll try a few more permutations, but any pointers would be welcome.

In bootlog:

so check that both SoC mac and external swicth qca8337 port 0 are configured in sgmii mode.
And show your current dts-file.

I feel like I should be configuring the switch in here, but I looked at other devices like the Linksys SPNMX56 and it wasn't clear to me how to map something like that to this device.

Of course, the current behaviour makes sense if the qca8337 is operating in dumb switch mode because I haven't configured it.

I'm not familiar enough with at79 but you need add something like:

	phy-mode = "sgmii";
	fixed-link {
	      speed = <1000>;
	      full-duplex;
	};

to eth0 and phy0 nodes in dts-file (for mac-to-mac connection phy-mode and speed must be set explicitly).
I'm not sure that qca8337 driver set phy-mode correctly. In last case you have to set sgmii mode and speed with qca,ar8327-initvals. See qca8337 specs for regs and values.
