The libertas driver made its debut in the OLPC XO laptop, where it drives a Marvell 88W83886 USB device. In addition to the USB front-end, the driver now includes support for CompactFlash, SDIO, and GSPI interfaces.

AmbiCom WL54CF (CF)

- Pretec CompactWLAN 802.11g CFEWGS
- prototype boards
- OLPC laptop
- station (with limited roaming support)
- Mesh on USB devices (802.11s like)
- Mainly interesting for developers, it allows to switch various debug messages on and of.
- Can extract a firmware out of a binary file.
You can get the source of the tools via
git clone git://git.infradead.org/users/schurig/libertas-tools.git tools
All devices need firmware.
Download the latest image from OLPC's libertas firmware page and rename it usb8388.bin, then place it in /lib/firmware/ and be happy.
Get the libertas-tools from above and change into the fwcutter/ directory. Type make. The makefile will download a binary driver, extract the firmware out of it, checks it. Copy the two firmware files libertas_helper.fw and libertas.fw from the fwcutter/ directory into the /lib/firmware/ directory.
- Claud Yu got the driver working, using a firmware 8.73.7.p3 (downloaded from marvell.com). The 9.70.3.p18 firmware doesn't support the CMD_802_11_DATA_RATE command that the libertas driver currently needs.
The GSPI firmware (version 9.70.3p37) will be available for download from marvell.com, otherwise you can get it here if it is not yet listed there. Copy spi8686_helper.bin to /lib/firmware/libertas/gspi8686_hlp.bin and spi8686.bin to /lib/firmware/libertas/gspi8686.bin.
