Installation on (not-quite?)-supported Asus Travelair AC (MT7620+Uboot)

Hi all, I have this MT7620-based device. Factory firmware is based on some Linux 2.6. It runs telnetd and serial getty by default, with authentication. Known telnet root password is 20080826. Currently <20€@Amazon.

I have managed to loadb & bootm a OpenWrt trunk snapshot ramips initramfs image to a functioning root prompt.

The device seems to be similar to the Gl.Inet MT300N and MT750. The initramfs snapshot for MT750 detects a PCI-Bus. Both seem to detect MTD&Partitions.

Here is the serial log from factory firmware bootup through login, some commands, and to power off:

HW - Notes:

  • Easily accessible, labelled serial port header
  • Easily accessible, labelled I2C header
  • As of yet unidentified Header with Pads (RN RP TN TP GND) (MDIO, USB, RJ45?)
  • Dual WLAN (maybe only one can be powered at the same time)
  • MicroSD reader and on SD card reader.
  • built-in Battery
  • USB micro OTG?
  • No LAN plug externally

I'm going to continue working on this, but wanted to already get this out there

Sorry for bumping an old thread, but I was curious wether or not there is any progress on the device. I have one of these lying around.

Hi Dun, no, I haven't worked further on that device (yet). I check every few months, but the situation regarding MT76 does not seem to have entirely stabilized, and (up-2-now) there was no interest in the device. Have you found out anything beyond what I wrote in the 2 posts above?

I'm thinking/hoping, the Header with Pads (RN RP TN TP GND) turns out to be RJ45. But I'm not sure, how to connect a Jack, and don't want to do damage before being certain. That would then enable TFTP-loading kernels+initramfs experiments.

What primary use-cases are you aiming for?
