I happen to have one of these, and I was wondering if OpenWRT is ever coming to it. And I come bearing gifts: Here's a copy of dmesg https://www.toptal.com/developers/hastebin/xeyabenove.yaml and as it gives full telnet and SSH access, I can run pretty much anything you'd like for more information to try and get this unit up and running.
Same device?
Yup. that's the very same device. And that (and the other, even older) thread on this device went absolutely nowhere. I'm hoping I can push this forward a bit.
Start by checking if it's supported by main line kernel.
A quick search points to https://github.com/torvalds/linux/blob/master/drivers/clk/mediatek/clk-mt7629.c
In fact, reading the first few lines of the dmesg output, I notice
Linux version 4.4.198 (heidi_wen@sw4-build-server) (gcc version 5.4.0 (LEDE GCC 5.4.0 unknown) ) #1 SMP Tue Jun 1 18:14:41 CST 2021
So this thing is possibly running a variant of LEDE. Which should be good news, right?
Oh, and support is in the OpenWRT kernel since the 4th of November 2019: https://git.openwrt.org/?p=openwrt/openwrt.git;a=commitdiff;h=109e614d906995cc7d9ec1233a13eb8be1823ba3
I posted that original thread… Nice to see someone else has this router haha
Also glad to see that support for the SoC is already in the kernel.
