Head Weblink HDRM200 is a dual-sim router based on MT7620A. The detailed
specifications are:
- MT7620A (580MHz)
- 64MB RAM
- 16MB of flash (SPI NOR)
- 6x 10/100Mbps Ethernet (MT7620A built-in switch)
- 1x microSD slot
- 1x miniPCIe slot (only USB2.0 bus). Device is shipped with a SIMCOM
SIM7100E LTE modem.
- 2x SIM slots (standard size)
- 1x USB2.0 port
- 1x 2.4GHz wifi (rt2800)
- 1x 5GHz wifi (mt7612)
- 1x reset button
- 1x WPS button
- 3x GPIO-controllable LEDs
- 1x 10 pin terminal block (RS232, RS485, 4 x GPIO)
Tested:
- Ethernet switch
- Wifi
- USB slot
- SD card slot
- miniPCIe-slot
- sysupgrade
- reset button
Installation instructions:
Installing OpenWRT for the first time requires a bit of work, as the
board does not ship with OpenWRT. In addition, the bootloader
automatically reboots when installing an image over tftp. In order to
install OpenWRT on the HDRM200, you need to do the following:
* Copy the initramfs-image to your tftp-root (default filename is
test.bin) and configure networking accordingly (default server IP is
10.10.10.3, client 10.10.10.123). Start your tftp server.
* Open the board and connect to UART. The pins are exposed and clearly
marked.
* Boot the board and press 1.
* Either use the default filename and client/server IP-addresses, or
specify your own.
The image should now be loaded to memory and board boot. If the router
reboots while the image is loading, you need to try again. Once the
board has booted, copy the sysupgrade-image to the router and run
sysupgrade in order to install OpenWRT to the flash.
Notes:
- You control which SIM slot to use by writing 0/1 to
/sys/class/gpio/sim_switch/value. In order for the change to take
effect, you can either use AT-commands (AT+CFUN) or power-cycle the
modem (write 0/1 to /sys/class/gpio/power_mpcie/value).
- RS485 is available on /dev/ttyS0.
- RS232 is available on /dev/ttyS1.
- The name of the ioX-gpios map to the labels on the casing.

v3->v4:
* Update commit. I had forgot to remove instructions to compile a
ramdisk. This now done automatically (thanks Petr Štetiar).
* Fix image size in the Makefile (thanks Petr Štetiar).
* Group the wifi-LED together with other devices. I see that there are
several lone cases with the same LED name, but in order to reduce the
changes made by this patch I have left them as-is (thanks Petr Štetiar).
v2->v3:
* Build initramfs automatically, which means that ramdisk is now enabled
the mt7620-target. Due to this change, an initramfs-image is built for all
deivces, but this seems to be ok when looking at other targets (mt7621)
(thanks Petr Štetiar).
* Use generic board/model detection, updated the match in 01_leds and
02_network (thanks Petr Štetiar).
* Changed the device/target device in the Makefile to match the
compatible-string in the DTS (thanks Petr Štetiar).
* Use the user-space gpio-switch alternative instead of gpio-export in
the DTS (thanks Petr Štetiar).
* Update name of flash node in DTS to the more generic "flash0" (thanks
Petr Štetiar)..
* Fix typo in commit message (mt7621->mt7612) (thanks Tom Psyborg).
* Added the QMI and option drivers, as well as uqmi, so that the modem
is available for use out of the box.
v1->v2:
* Add SPDX line to DTS (thanks Rafał Miłecki).
