It does not support new chipsets (BCM5356, BCM5357, BCM5358, BCM47186, BCM4331) or 802.11ac devices (BCM4352, BCM4360).įor old devices it often has more functionality than the brcm80211 drivers. It's based on old Broadcom's sources (version 5.10.56.27.3) and supports many old 802.11g devices but very few 802.11n devices (BCM4716, BCM4717, BCM4718). It contains closed source MIPS binaries with a few trivial open source files that allow it to be compiled against any kernel version. If you have to do some modifications to generate a valid image and it boots on your device please send a patch to the mailing list for inclusion into OpenWrt.īroadcom-wl contains the proprietary closed source Broadcom driver. If that does not work you could download the image builder or check out OpenWrt from the svn and edit target/linux/brcm47xx/image/Makefile to fit your needs. If you want to flash OpenWrt from the default firmware, use the image for your device if there is one, otherwise use the x image.įor sysupgrade always use the generic image x independently from what image you initially flashed to your device. Many vendors like Netgear and Linksys currently are using their own image formats to prevent an incorrect image from being flashed to their devices, these images contain the same code as the generic image, but with some special header data just for this device, mostly containing the internal device name and the version of this firmware. The main image is x which is in the generic image format used by the Broadcom SDK for these devices. The current goal is to boot one image on all the different devices using SoC of the bcm47xx family.
