The libertas driver is a collection of modules providing support for Marvell Technology Group's Libertas chipsets. On this page we will only detail the setup of the driver for the SDIO interface modules compatible with 88w8686 chipset, used for example on the APF27's wireless extension board, the APF51Dev or on APF27_PPS devt board.
The Linux drivers are available since 2.6.24 kernel, thanks to the community effort to rewrite Marvell's proprietary drivers.
Installation
- Libertas drivers are already installed on your rootfs (if you built it with an APF27/PPS/APF51 as target). If not, it's explained here.
- The drivers require 2 proprietary firmwares to be loaded in the chip before use. If not already present in /lib/firmware/, here is the procedure to follow:
Firmware installation
$ make menuconfig
Target packages --->
Hardware handling --->
Firmware --->
[*] linux-firmware --->
WiFi firmwares --->
[*] Libertas SD 8686 v9
$ make
- reflash your rootfs
Usage
- Load driver:
# modprobe libertas_sdio lib80211: common routines for IEEE802.11 drivers libertas_sdio: Libertas SDIO driver libertas_sdio: Copyright Pierre Ossman libertas_sdio mmc1:0001:1: firmware: requesting sd8686_helper.bin libertas_sdio mmc1:0001:1: firmware: requesting sd8686.bin libertas: 00:19:88:11:2d:b8, fw 0.70.8p0, cap 0x00000000 eth1 (libertas_sdio): not using net_device_ops yet libertas: eth1: Marvell WLAN 802.11 adapter
If it's not working, you can activate debug like this to report your problem:
# modprobe libertas libertas_debug=0xffffffff # modprobe libertas_sdio
- Bring up the corresponding network interface:
# ifconfig eth1 up ADDRCONF(NETDEV_UP): eth1: link is not ready
Going further
- Now you can use the general instructions here to setup your WiFi network (replace wlan0 with eth1)
