Add support for TP-Link Archer AC750 C2 V5

For Developers
1

Hello, I'd like to get OpenWrt workin on an old TP_MODEL_C2V5. It's useless with the stock firmware so has been replaced, but I'd like to still use it as an access point. I've tried a number of attempts at getting a dts configuration that works, but without luck. Anyone willing to help? I solder on headers to the uart so I can try configs.

Here's what I know:

SoC: MT7620A (580 MHZ)
RAM: 64 MB
Flash: 8MB (GD25Q64CSIG)
Wifi: SoC internal + MT7610EN
Ethernet: 5x 10/100/1000 Mbps QCA8337

Bootlog from the serial port:

I'm by no means any hero with DTS myself, it looks like there are a few MT7620 devices supported already that have an Atheros switch as well: Engenius ESR600 and Lava LR-25G001. I'm not sure how much the AR8327 and QCA8337 differ (but Qualcomm has renamed a lot of models for marketing purposes with minimal changes often, from what I understand).

If you can use the same driver and DTS binding (and the ar8327 code in the OpenWrt tree has some 8337 matches, as well as the ar8216 code), the trick would be to find out the initialisation values for the switch. Looking at the Lava and Engenius DTSes, those really seem to be device-dependent.

AR8337 and QCA8337 are the same chip, just rebranded - AR8327 is its immediate predecessor (e.g. used on ath79/ tl-wdr4300); there are N-variants (e.g. QCA8337N) for either of these, offering some hardware acceleration (if supported by the driver, so not yet).

(the n variant offer the hnat feature that we don't use since it's only supported with the qsdk

Thanks. I've been trying the existing ones but pretty much guessing on what values for things like qca,ar8327-initvals and others needed. No luck so far but I might reflash with stock to see if I can dump the switch registers with that.

Hello, I'd like to get OpenWrt on an C2V5 too. Did you succeed?

7

No, sorry, I didn't. I didn't know enough about how the QCA8337 works to get the correct values to get it working and didn't manage to pique anyone's interest on IRC. Plus I thought maybe I should wait until this PR was merged.

I went with a different device, but I'm still interested in putting the C2V5 to use if you have more luck than I did.

Apparently we can dump the qca8337 and 7620 registers from the stock firmware using ./bin/qca8337_switch read reg. List of all applets of that executable below:

file qca8337_switch in ASCII, data at offset 0x003418:
...
socketUsage: 
 %s reset   - reset qca8337 switch
 %s init                - init qca8337 switch
 %s read reg            - read qca8337 switch register
 %s write reg value     - write qca8337 switch register
 %s rphy phy reg        - read qca8337 phy register

 %s wreg reg value      - write 7620 cpu register
 %s rmii phy reg            - read 7620 phy register
 %s wmii phy reg value      - write 7620 phy register
 %s vlan dump           - dump qca8337 vlan entries

 %s vlan del vid        - delete qca8337 vlan entry with vid
 %s vlan flush          - flush qca8337 vlan entries

Of course, we need to become SuperUser before using this command in ssh.

Hello, did anything work out with this device? I really want to install openwrt on it, I don’t understand at all how it works, is there any success?

Sorry @RZC-ALEX, I didn't have any success. I'm also not familiar with the intricacies of OpenWRT and my original post didn't get much traction so the device is sitting on a shelf. Instead I picked up a Xiaomi Redmi AC2100 and it's been running fine.

If you have more luck than I did please let me know, as I could still use the device elsewhere.
