The results can be used to improve OLPC screen simulations, to accurately describe the OLPC screen limits, and perhaps to improve the OLPC screen. (I'm thinking a 5x5 loadable convolution matrix in place of the hard-wired swizzle function would be very useful.) |

how to flash an update
According to Jim Gettys, the procedure is as follows:
- Put the Olpc-Q2B76.rom image on a USB device as Q2B76.rom
- Put the jffs2 devel "build 299" OS image on a USB device as Build299.img (see tinderbox report)
- Boot, stopping at the OpenFirmware ok prompt by hitting the spacebar
- Run copy-nand disk:\Build299.img
- Run flash disk:\Q2B76.rom
example app
The Hello-1.0.0.tar.gz file contains a somewhat normal "Hello, world!" app for Sugar. (normal: Makefile and *.c files without exotic non-standard libraries)
Hopefully I can get some help turning this into a demo of the Sugar API stuff, two different ways:
- the minimum (which should be nothing)
- everything (sharing over the mesh, etc.)
