That is easy: Yes!
I develop my app under Linux+X11, test it and then link it with libnx
and run it on my target.
Basically, all my code that is calling hardware specific stuff is #ifdef
out when compiling for PC.
During linking, I either use X11 libs (for PC) or libnx for embedded.
This is all that I do differently.
However, some of the X11 interfacing is a little different on X11 than
nanoX, but for testing it does not matter.
On embedded platform I use standard Linux and Busybox.
Most of the flash memory is taken by TTF fonts because my user interface
is rather involved (1280x1024 LCD).

Hi Martin,
I think you're right, my first email might have been a little confusing,
so I'll try to add some detail.
My embedded target is a Nios II 32-bit processor, from Altera, which is
actually inside an FPGA packed together with most of my custom hardware.
Our system features an 800x600 LCD screen, 100 Mbps ethernet, PS2 mouse
and keyboard.
Up to now, we've been using the vendor-provided IDE (which is called
Nios IDE and is based on Eclipse), running on Windows. It is turtle
slow, but since it integrates fairly well with the debug tools and all
programming hardware, I'm coping with it.
We've been able to manage things without any operating system, but this
is likely to change in a while. We are considering the use of uClinux.
As far as I know, the uClinux kernel can be easily configured to run
from flash, or to copy itself to ram.
What I was hoping to do was develop/debug most of the application on the
PC, under Linux-NanoX. Then, when I had the user interface working ok, I
would cross-compile the app to uClinux-NanoX.
I'd just like to know if it is possible! :)
Thanks,
Ricardo.
