TP-Link RE220 V3 hardware support

Can TP-Link RE220 V3 be supported?

I tried to upload the RE220 V2 factory firmware file and it did not work.
See pic, says hardware version is V3tp-link-re220-v3

Seems the internal pictures are here https://fccid.io/2AXJ4RE200V5/Internal-Photos/2010TW0004-Internal-Photo-Rev01-5215726

looks like it is MT7628

Just taken delivery of one of these myself hoping to put OpenWrt onto it but mine's a V3 too. Hey ho. I can still use it with the TP-Link firmware but I'd have preferred a proper router OS. :wink:

I can see what might be a QSPI flash on those pictures but no DDR. Wonder if it's the K with internal 8MB?

Suppose I could dismantle it to see if I can get to a serial console. Finding the time ...

Is there still no support for RE220 V3. Maybe a modified image of v2 would work with v3?

See also TP-Link RE220 V1

I did connect to serial on V1 and was able to run initramfs from re220-v2. It mostly worked.

In referenced post, I looked at the differences for the re220-v2 and various re200 models. Didn't see much different. I'm just not sure how to take the next step.

Question for devs: Is the .id value in the platform.sh defined solely in OpenWRT code or does it have to match some existing value from the hardware?

For the serial connection, the holes are there. The case is glued shut. Only way I found was to cut it with roto tool cutoff wheel.

Here are some pics:
RE220-v1-serial1

RE2220-v1-serial2

RE220-v3-serial On V3 the holes are a little farther away from the power end.

Could you modify an image to make it work on v3? Im willing to take the risk of brick so im available :smiley:

I'm planning to get back to this RE220 stuff (v1 and v3) in the coming days. Don't think I have the knowledge/experience to get across the finish line. Any guidance from grand-masters would be helpful.

RE220 v3 is a no go for OpenWRT.

Looks like tp-link downgraded the hardware for RE220 v3.
I connected serial uart.
Facing front of device, serial connector is on the right.
You want to use the top 3 pins which are Tx(white) Rx(green) and GND(black). The fourth is Vcc, leave it disconnected. Com settings are 8N1 at 115200 with flow control off.

U-Boot shows 16MB RAM and 'flash -layout' command shows 4MB flash. These specs don't meet the minimum requirements. Note that V1 is 64MB RAM and 8MB Flash.

Also, 5GHz chip may be newer based on these messages:
[mt7628k]SCANNING, pAd->hw_cfg.bbp_bw = 1
[mt7613b]SYNC - sync_fsm_scan_req_action:[1107] LAST_CH: 0, BAND: 0

Some interesting command output
