From e58e49bdbe3b2a07cd43f82507e89d4fa4736edd Mon Sep 17 00:00:00 2001 From: Piotr Dymacz Date: Thu, 8 Feb 2018 22:28:07 +0100 Subject: ar71xx: 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. Specification: - 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 (AR9344), 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 --- target/linux/ar71xx/image/generic.mk | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'target/linux/ar71xx/image') diff --git a/target/linux/ar71xx/image/generic.mk b/target/linux/ar71xx/image/generic.mk index add3aa32a7..f23c208caf 100644 --- a/target/linux/ar71xx/image/generic.mk +++ b/target/linux/ar71xx/image/generic.mk @@ -1101,6 +1101,18 @@ define Device/bhr-4grv2 endef TARGET_DEVICES += bhr-4grv2 +define Device/wam250 + DEVICE_TITLE := Samsung WAM250 + DEVICE_PACKAGES := kmod-usb-core kmod-usb2 -swconfig + BOARDNAME := WAM250 + IMAGE_SIZE := 15872k + MTDPARTS := spi0.0:256k(u-boot)ro,64k(u-boot-env),128k(nvram)ro,15872k(firmware),64k(art)ro + SUPPORTED_DEVICES := wam250 + IMAGE/sysupgrade.bin := append-kernel | pad-to $$$$(BLOCKSIZE) |\ + append-rootfs | pad-rootfs | append-metadata | check-size $$$$(IMAGE_SIZE) +endef +TARGET_DEVICES += wam250 + define Device/wlr8100 DEVICE_TITLE := Sitecom WLR-8100 DEVICE_PACKAGES := kmod-usb-core kmod-usb2 kmod-usb-ledtrig-usbport kmod-usb3 \ -- cgit v1.2.3
