From: Hauke Mehrtens Date: Mon, 16 Sep 2013 21:09:10 +0000 (+0000) Subject: brcm47xx: Add support for Huawei E970 X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c78e4fb220169b5ee8358f7b2582972c00b88fd7;p=openwrt%2Fstaging%2Fblocktrron.git brcm47xx: Add support for Huawei E970 This patch adds support for Huawei E970 wireless gateway devices. It has been tested on an E970 labelled as T-Mobile web'n'walk Box IV. E960/B970 should work too, from what I know it's basically the same hardware. The device has a Broadcom BCM5354 SoC and a built-in 3G USB modem. It uses a hardware watchdog which needs GPIO-7 to be toggled at least every 1-2 seconds. This patch uses gpio_wdt module (see my previous patch today) to take care of this. Tested and works: 3G wan, wlan+LED, VLAN config, failsafe using reset button, image to be used for upgrade from OEM firmware's web interface Link to the wiki page I've created: Issue: * lzma-loader crashes, so gzipped kernel is used. Presumably due to watchdog reset during kernel decompress.
