  • 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.
  • 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.
  • There are still some issues regarding the openness of the firmware <trac>46</trac>
  • Discussions about how to open libertas firmware [1][2]
