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

• reboot by urjtag. save below to m1reboot.sh

#!/bin/bash
BATCH_FILE=`mktemp`
cat > ${BATCH_FILE}<<EOF
cable milkymist
detect
instruction CFG_OUT 000100 BYPASS
instruction CFG_IN 000101 BYPASS
pld reconfigure
EOF

jtag -n ${BATCH_FILE}
rm -f   ${BATCH_FILE}

Test Plan

• Webupdate
• All patches compile and render fine
• For test filesystem, try to copy from/to Milkymist One by using lftp, filezilla.
• Input system. keyboard, mice
• USB-MIDI controller. I have ICON for test
• react to OSC message. can test by midi2osc.
• Sound system. MIC, line in and line-out
• MIDI port by using usb-midi converter.
• DMX chain mode and DMX controller mode
• VGA output, 640x480, 800x600, 1024x768
• Video input. I have one camera for test.
• IR remode
• Test switch patches by some saved performance files.

Linux

Our Linux development is focused here: https://github.com/milkymist/linux-milkymist

boot OpenWrt

1. wget http://fidelio.qi-hardware.com/~xiangfu/build-milkymist/milkymist-openwrt.minimal-20120127-1251/openwrt-lm32-root.ext4 -O initrd.bin
2. wget http://fidelio.qi-hardware.com/~xiangfu/build-milkymist/milkymist-openwrt.minimal-20120127-1251/simpleImage.milkymist_one -O boot.bin
3. copy them to your tftp folder like /var/lib/tftpboot, change your IP to 192.168.0.14
4. press 'ESC' while m1 booting. type 'netboot'
