ath79: add support for Samsung WAM250
Samsung WAM250 is a dual-band (selectable, not simultaneous) wireless hub, dedicated for Samsung Shape Wireless Audio System. The device is based on Atheros AR9344 (FCC ID: A3LWAM250). Support for this device was first introduced in e58e49bdbe (ar71xx target). Specifications: - Atheros AR9344 - 560/450/225 MHz (CPU/DDR/AHB) - 64 MB of RAM (DDR2) - 16 MB of flash (SPI NOR) - 2x 10/100 Mbps Ethernet - 2T2R 2.4/5 GHz Wi-Fi, with ext. PA (SE2598L, SE5003L) and LNA - 1x USB 2.0 - 4x LED (all are driven by GPIO) - 2x button (reset, wps/speaker add) - DC jack for main power input (14 V) - UART header on PCB (J4, RX: 3, TX: 5) Flash instruction: This device uses dual-image (switched between upgrades) with a common jffs2 config partition. Fortunately, there is a way to disable this mode so that more flash space can be used by OpenWrt image. You can easily access this device over telnet, using root/root credentials (the same also work for serial console access). 1. Make sure that your device uses second (bootpart=2) image using command: "fw_printenv bootpart". 2. If your device uses first image (bootpart=1), perform upgrade to the latest vendor firmware (after the update, device should boot from second partition) using web gui (default login: admin/1234567890). 3. Rename "sysupgrade" image to "firmware.bin", download it (you can use wget, tftp or ftpget) to "/tmp" and issue below commands: mtd_debug erase /dev/mtd3 0 $(wc -c /tmp/firmware.bin | awk -F' ' '{print $1}') mtd_debug write /dev/mtd3 0 $(wc -c /tmp/firmware.bin) fw_setenv bootpart fw_setenv bootcmd "bootm 0x9f070000" reboot Revert to vendor firmware instruction: 1. Download vendor firmware to "/tmp" device and issue below commands: fw_setenv bootpart 1 sysupgrade -n -F SS_BHUB_v2.2.05.bin Signed-off-by: Piotr Dymacz <pepe2k@gmail.com>
