Support for TP-Link Archer C20 v6

For Developers
1

Hello,

This is my first time contributing to the forum.

I would like to help with adding support to the TP-Link Archer C20 v6.
I have access to that device as well as a TP-Link Archer C20 v5.

Can someone guide me through what I should look into to make sure it is compatible with the current OpenWRT release?

Thanks!

you never make a new device compatible with the current release, but the coming one, at best.

C20 V5 is on the thin end. Days are counted if V6 is same with minor modifications.
Lets start, set OEM log level to debug and capture boot logs, from there try

  • identify SoC type
  • identify flash amount (goes under names like mtd and ubi)
  • memory amount
  • wifi hardware
    If you cannot find those answers in log yourself:
    Clean last 3 parts of MAC addresses in output, public IP addresses etc and upload to smth like pastebin.
    8MB firmware file https://www.tp-link.com/es/support/download/archer-c20/v6/#Firmware adds some hope.

Thanks!

I took it apart here's the hardware that's on it:

SoC: Mediatek MT7628AN
RAM: Zentel A3R12E40DBF-8E
FLASH chip: XMC XM25QH64CHIQ
Wifi Hardware: Mediatek MT7613BEN

I will get back to you with more information when I get the logs.

64Mbit eq 8MB flash, it is very basic device.

And are today already discouraged, 8mb devices will be EOL:ed with the current release.

There is some work done to actually support them, will see how it goes, if it is very similar to V5 probably best is to backport on the spot to v23...

Hello Georgio, I'm trying to install openwork in archer c20 v6, have you tried that ? Do you know if openwrt works in this device?
I'll appreciate your answer.
