- The OLPC XO laptop uses a 88w8388 baseband processor along with a 88w8015 rf transceiver connected via an internal USB interface.
Firmware
The Libertas firmware is separate from the XO-1's Open Firmware boot firmware.
- As of November 2008, Ricardo Carrano recommends firmware version 22.p18.
- http://dev.laptop.org/pub/firmware/libertas/RELEASE_NOTES provides differences between Libertas firmware releases.
- How to flash the Libertas firmware (Last edition: 2006-11-03)
- The XBox 360 wireless module is also based on the 88w8388 and possibly can be used with the olpc firmware.
- http://wiki.free60.org/WifiAdapter
- http://www.free60.org/wiki/Wifi_Adapter
- incompatible firmware loader
- 4Mbit SPI flash
- uses 88W8030 RF chip
- There is a project to take the driver developed for the OLPC and utilized it for all of the libertas family including 88w8385 cf cards: http://projects.linuxtogo.org/projects/marvell8385/
- Linux 2.6.24 will include support for 88w8385 (compact flash + sdio) mode and 88w8686 (sdio), using the OLPC driver.
