Hey Mansoor

First off, welcome to the RockBox developer team :)

If you are only writing plug-ins, as Tom says, do all your work in

And as Linus says, "make zip" in your target-build directory will create a
Rockbox install zip; and "make install" in your sim-build directory will
make the simulator pretend that "sim-build/archos" is the root directory of
the simulated Jukebox.

I personally have an old fashioned embedded-engineers machine (ie. slow
cpu/slow hdd/cheap electric bill/etc) and find "make zip" and "make
install" too slow to use repetetively.

My solution is that the FIRST time I do a build I do the full:

   make install

   make zip
   unzip -d /cygdrive/m/.

("m" is the drive letter that my Jukebox lives on ("M"usic))

Then, as I tweak my plugin (so it does what I want - rather than what I
typed) I use:

   make;cp myplugin.rock archos/

   cp myplugin.rock /cygdrive/m/.rockbox/rocks/

You may notice that I do the make and copy all-in-one for Sim, but
seperately for target... This gives me time to connect the unit or the copy
will say something like "drive not found" ...The sim is a one-liner purely
for the convenience of only having to type once.

When I finish my current training course, I will update the DevKit at
Cyborg Systems (it will be 3.03) to inlude a number of things, one of which
is "F-Key keyboard short-cuts" to these, and other, commands.

With the method above, the LATEST "myplugin" will actually appear in the
root directory of the simulator (ENABLE "SHOW FILES: ALL or SUPPORTED"),
this means I can start it quickly without hunting it down through the menu

There are a dozen other short-cuts, but that should get you up to good
speed now.

Having rewritten the UI recently (available from Cyborg Systems Homepage),
I have already considered adding a command line option to auto-run your
plugin as rockbox-ui-sim starts automatically ...but I've kinda got my
heart set on getting it to do the grey-scale stuff first, as that would be
of more use to me personally this space -> <-

Let us know if you need any more tips and tricks of the trade ;)
