A.K.A. Minew, MS93MFZ_V1.0, MS93MF6_V1.2, MT7628, Thingoo, 2ABU6-G1 Thanks to Monadnock for a lot of the pin labels

snippets

play with the LEDs

kill the pubmsg service 

kill -9 `ps w|grep watchdog_loop|grep -v grep|awk '{ print $1 }'`
kill -9 `ps w|grep autopubmsg|grep -v grep|awk '{ print $1 }'`
killall -9 pubmsg

Random color animation: 

while true; do head -c96 /dev/urandom > /dev/ws2812 ; usleep 50000; done

Draw a (bad) VU meter: 

echo -en '\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\xff\x00\x00\xff\x00\x00\xff\x00\x00\xff\x00\x00\xff\x00\x00\xff\x00\x00\xff\x00\xff\xff\x00\xff\xff\x00\xff\xff\x00\xff\xff\x00\xff\xff\x00\xff\x00\x00\xff\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00' > /dev/ws2812

or use a custom built File:Fartnet.gz to listen as a fake artnet endpoint (source here) to get this:

connecting UART

New firmware has a script that install openssh-server, so UART is no longer required to get things up and running!

/!\ don't connect PoE and UART, you will fry the main board; there is a 43v difference in ground planes.

use 3.3V logic to be safe

For best results (prevent console glitches and boot loops), disconnect UART VIN and connect regular (micro) USB power

Run terminal client in 56k 8N1: minicom -D/dev/ttyUSB0 -b57600 -o And make sure Hardware Flow Control is off: Ctrl+a, o, choose Serial port setup, f

install secure shell daemon

Connect to Minew AP (wifi).

Login with default credentials, if it doesn't work; hold reset pin atleast 30 seconds while booting device.

Update firmware (see below).

Configure Minew to use your network with wifi or ethernet in the Network tab.

Take note of IP address in Status tab.

Disconnect from Minew AP.

Visit http://thingoo/cgi-bin/installssh (you might need to fill in its IP address).

After it is installed you should be able to SSH to the device!


gain root access by #updating firmware and run the following: 

opkg update
opkg install openssh-server
vi /etc/ssh/sshd_config

make sure PermitRootLogin yes is set for (ch)easy login 

/etc/init.d/sshd restart

updating firmware

The current version at the time of writing is v3.2.2

  • login to the router (http)
  • go to tab Other (the last tab)
  • scroll to FIRMWARE UPGRADE
    • either choose USB and put the firmware as thingoo-upgrade.bin on the root of a USB stick (case sensitive)
    • or choose put the firmware on a (local) webserver and fill in its URL (root:kakhoofd). Case sensitive: chances are, you have to rename the file thingoo-upgrade.bin!

root password

The password as of yet is unknown (you can flash other firmware with a known/empty password so no real problem).

The shadow hash is $1$Sevciuy0$CRuXyRAOWeathkwz1T00I1 (md5crypt) and is not in the 13GB Rocktastic12a password list, nor is it found by hashcat -O -a 3 -m 500 hash.txt -1 ?l?u?d ?1?1?1?1?1?1?1 --increment, which means, it either consists of punctuation marks/spaces (?s), or is 8 bytes long or longer, which the latter would take roughly a week on 8 × RTX3090s to verify.

troubleshooting

ModemManager

Some Linux distro's hijack the serial port for modem usage; when you're experiencing problems, try and disable the ModemManager service: 

systemctl disable ModemManager.service
systemctl stop ModemManager.service

Hardware flow control

If your serial is working intermittently, make sure Hardware flow control is off; for minicom it's: Ctrl+a, o, choose Serial port setup, f

If your terminal glitches or if you have boot loops, make sure you have a proper power supply and don't mix several supplies (i.e. PoE, USB, UART)
