From a92c64e8ae38f6a221823610c4a2f454c813c484 Mon Sep 17 00:00:00 2001 From: Oliver Fleischmann Date: Thu, 20 Jul 2017 21:02:33 +0200 Subject: [PATCH] ramips: add support for Loewe WMDR-143N 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").
