The WMDR-143N is a small module originally used as a Wifi client
in some Loewe smart TV sets. It is sold cheaply at german surplus
shops. The module contains a RT3662 SOC.
Specifications:
- 500 MHz CPU Clock
- 1x 10/100Mbps Ethernet (pin header)
- 32 MB of RAM
- 8 MB of FLASH
- 2T3R 2.4/5 GHz (SOC internal)
- 3 Antennas on PCB
- UART pads on PCB (J3: 1 = +3.3V, 2 = RX, 3 = TX, 4 = GND), TX
and RX are 3,3V only! The square hole is pin 1
- Power supply pads on PCB (J6: 1 and 2 = +5V, 3 and 4 = GND)
The square hole is pin 1
The original firmware has two identical kernel/rootfs images and
two "Factory" calibration data blocks in flash. The LEDE image
leaves only the first "Factory" block in place and uses both
"Kernel" blocks and the redundant "Factory" block together to gain
enough space for the jffs2 partition.
Flash instructions:
You need UART and Ethernet connections to flash the board. Use
the LEDE "sysupgrade.bin" image with tftp.
Apply power to the board and in the first 5 seconds, hit 2 to
select TFTP upload. The bootloader asks for board- and server IP
addresses and filename.
Alternate method: With the vendor firmware running, assign an IP
address to the ethernet port, tftp the firmware image to
/tmp and write to mtd4 ("KernelA").

The factory image has an uImage header covering the entire image and
not only the kernel. The original uImage header which covers only the
kernel is appended to the end of the image.
During LEDE boot the uImage rootfs splitter skips the whole filesystem,
can't find a valid filesystem magic and panics.
The last known working version was OpenWrt 14.07, which simply kept on
searching for an uImage header if the first found didn't resulted into
a working rootfs. This behaviour is kind of error prone since it could
produce false positives.
Since the sysupgrade image works fine in combination with the tftp
recovery for doing the initial installation of LEDE, simply drop the
factory image.

The Sitecom firmware upgrade file has SENAO_FIRMWARE_TYPE 2 set. This
looks rather wrong since SENAO_FIRMWARE_TYPE 2 is kernel only but the
file is way to big for only including a kernel.
The factory image need to have the dlf file extension. Otherwise the
Sitecom firmware rejects the file.
The stock firmware uses the following mac addresses:
LAN: 00:0C:F6:AA:BB:D8 (u-boot env: ethaddr)
2,4: 00:0C:F6:AA:BB:D8 (EEPROM)
5: 00:0C:F6:AA:BB:DC (EEPROM)
WAN: 00:0C:F6:AA:C8:43 (u-boot env: wanaddr)
Assuming the mac address range :D8 to :DC is reserved for this device,
the MAC addresses were reorder to have a unique MAC address for each
interface:
2.4GHz: 00:0C:F6:AA:BB:D8
LAN: 00:0C:F6:AA:BB:D9
WAN: 00:0C:F6:AA:BB:DA
5 GHz: 00:0C:F6:AA:BB:DC
The first MAC is assigned to the 2.4GHz WiFi interface
to keep compatibility with the SSIDs printed on the case, which have
the last three sextets of the MAC address appended.
There are still issues with the rt2x00 driver. It is not possible to
use both wireless interfaces at the same time. The 2.4 GHz
wireless (PCIe) only works if the internal 5GHz wireless is/has been
enabled or used for scanning. The internal 5GHz wireless only works if
the 2.4GHz wireless (PCIe) was never enabled. Disabling the 2.4Ghz
after it was enabled will result in stations seeing the 5Ghz AP but are
unable to connect.
Due to the not optimal working wifi the manufacture, backup and storage
partitions of the OEM firmware are kept for now to allow an easy switch
back to the Sitecom firmware.

The image generation for TEW-691GR and TEW-692GR was broken since
79d02229 due to the move of the UMedia recipe to another Makefile.

- all subtarget specific defines are in their own files
- common defines left in main Makefile
- each subtarget makefile idefed with SUBTARGET
- all subtargets compile tested
- few seems to be broken/unneeded things marked with FIXME
