Few ideas
For linux
Remote debugging with gdb
c++ hello world
python and python hello world
pwm for rc servos
zedboard hexapod
using a microphone
audio output
vga output
dvi output
networking
voip / voip box
home gateway
3G dongle/connection
gps
pong
Qt program development
accelerometers
imu
onboard java compiler
seven segment/alpha numeric display
simple oscilliscope
weather station
For android
Hello world
remote debugging with eclipse
using a microphone
audio output
vga output
dvi output
touchscreen
I'd be happy to write some of these once I get a zedboard (looks like mid August) if I can get the time with work and studies.
Might be worthwhile doing a port of the arduino tools
like papillio has done with zpuino for those who don't want to use edk. Have a supplied basic set of peripherals in the bitstream that the software can use.
Could make it more attractive for some hobbiests and software people ? as less of a learning curve.First steps then if you want the full power you need to use edk.
Plus a cheap fmc to arduino wing adaptor with level shifters would be handy.
