XO1.75 Bringup
This page lists goals and plans for initial bringup of the XO 1.75 A1 motherboard, the first prototype of the XO-1.75 Laptop.

Note that a check in any one of the two columns is generally sufficient to prove that the hardware works.

Goals
The goal of a A-phase board bring-up is get a small number of boards to an acceptable state of functionality. At this point, a larger number of boards are modified to match and distributed for both extended testing of basic functionality (esp. memory stability) and development of software to access further functionality.
The following are the goals of this bringup:
Non-goals
Personnel in Taiwan
- Wad (EE), Richard (EC/OFW), Mitch (OFW), and Chris (Linux) from OLPC
- Mars (PM), Beckham Chen (EE), Gary Chiang (EE), Bryan Ma (EC Firmware) from Quanta R&D
Tools
- SPI FLASH programmers - preferably clip-on - qty 3
- Marvell debug dongles - qty 3 or more
- Marvell JTAG box - qty 3
- Does the eXtreme Debugger software work under Linux or Wine? If not, we may need another Windows system (in addition to Mitch's laptop) to run it. Perhaps we can borrow one from Quanta - or maybe we could try running it under Windows on an XO, or in an emulator on a Linux laptop.
Sequence of Events
Dates too vague yet to book travel
Hardware
Linux
After initial boot, this is mainly driver testing of hardware as functionality is confirmed with OFW.

Documentation
Early documentation may be obtained from a secure FTP site on dev.laptop.org:
sftp://dev.laptop.org/home/docs/1.75/ sftp://dev.laptop.org/home/docs/marvell/
If you already have a login on dev, let wad know and he will get you access privileges.
Information is also available on the Team Tech wiki.
Much of the documentation will be available on the XO 1.75 A1 board page.
Lodging
We will be staying at:
Our recommended medical provider is:
- The Taipei Adventist Hospital - English speaking, decent care, just make sure to bring your own soap, towel, and arrange for outside food delivery. There is a Burger King across the street, so your confederate can smuggle in food, and then answer "yes" to the question "Is that a Whopper in your pocket"?
