nanogui: Thread: ntetris demo on eCos

Hi all,

I'm running the ntetris demo on eCos (custom hardware).
The application seems to start correctly, however _before_ it draws 
anything on the screen I read on the debug serial port the following 
messages:

Nano-X says it is destroying client 8 resources but it is not clear 
which client it is referring to. How to understand which client it is 
talking about?



TIA,

: Nano-X says it is destroying client 8 resources but it is not clear

These messages are coming from printf()s in 
nanox/srvnet.c::GsDestroyClientResources().   I suggest
you add other printfs to determine which thread is 
causing problems.  It's probably the nano-tetris
demo, since that's the last one that was started...

I completely removed nano-tetris thread thus in the nano-x world there 
are just two threads (Nano-X server and Nano-WM) but I still got the 
messages about a client destruction:

Clearly I must find out which client in the world connects to the 
server. I have a hardware debugger so I can easily put breakpoints in 
the code but I don't know exactly where. Is GrOpen the one and only 
function used by clients to establish the connection with the server?



Thanks a lot in advance,

Just a guess, but are you running any kind of touchscreen calibrator on
startup?

If it doesn't work, you're not hitting it with a big enough hammer

No. Touch screen is autocalibrating so software doesn't need to take 
care of this.
