Develop

Milkymist Flickernoise main source code is C. the SDK can download at : http://milkymist.org/updates/2011-11-29/for-rc3/Flickernoise-lm32-rtems-4.11-SDK-for-Linux-x86_64.tar.bz2 the SDK include ALL you needs to develop Flickernoise. if you wnat compile those stuff from scratch. you can look info the scripts file: read the 'Makefile' under this project and the README.html. short intro about the compile steps:

1. compile the toolchian first
2. compile rtems
3. compile libfpvm (lib for rendering)
4. compile mtk the GUI
5. compile libs: libpng, jbig2dec, freetype2, mupdf, curl, expat, oscparse
6. compile rtems-yeaffs2. the filesystem we using in NOR flash
7. compile the host tools that flickernoise needed : https://github.com/milkymist/milkymist/tree/master/tools
8. compile Flickernoise.fbi
9. compile host tools we used to flash. urjtag: git://urjtag.git.sourceforge.net/gitroot/urjtag/urjtag

rtems

rtems is link the OS. if someone want write the Milkymist One driver and interested in real-time OS. then this is a good project look into.

Flickernoise

this is like the application. build with rtems. link the GUI. etc. give us a interface.

Rendering-libs

those libs is for rendering

libs

like: libpng, jbig2dec, freetype2, mupdf, curl, expat, oscparse. people can port more libs to Flickernoise.

Test

• boot from tftp

when m1 boot to BIOS. press 'ESC'. then type 'netboot' . m1(192.168.0.42) will try to load '/var/lib/tftpboot/boot.bin' under 192.168.0.14.

• direct flash the result to m1.

using Werner's tools. 'm1nor' under git://projects.qi-hardware.com/wernermisc.git, using script file under git://github.com/milkymist/flickernoise.git/flash
