Thinfirm 1.5
This documents the project to create a thin firmware and libertastf driver for the XO-1.5.
Introduction
The XO-1.5 uses the Marvell 8686 module instead of the 8388 that the XO-1s used. There is thin firmware and a libertastf driver for the Marvell 8388. New firmware and modified libertastf drivers need to be written.
Project plan
Ultimately, we will deliver a thin firmware and a working libertas tf driver to go with it. These will work on XO-1.5. However, it's better to split the larger task into several smaller sub-tasks. These are outlined below (already completed sub-tasks prior to this breakdown are excluded).
| ID | Milestone | Deliverable | Tests | Status |
|---|---|---|---|---|
| 1 | Compile full firmware build | sd8686.bin | Does full firmware load on XO-1.5? | Done |
| 2 | Thin firmware specification | Initial version of specification | Readable version of spec checked in. | In progress |
| 3 | wireless-testing kernel on OLPC?
Find out if wireless-testing will work on the OLPC. It's OK if some parts are broken, only concerned about booting with a command-line and full functionality of network and network tools. This will give us the ability to only work with one kernel. |
