nanogui: Thread: wrong colors

Hi,

I am using microwindow-0.90 on an intel pxa270 based board (linux-2.4.29). The 
problem is that the colors are weird on the screen. (I set MWPF_TRUECOLOR0565 
in the microwindows config file and set the framebuffer for 16bpp:

>fbset -n -depth 16 
mode "640x480-58"
        # D: 25.000 MHz, H: 31.095 kHz, V: 58.229 Hz
        geometry 640 480 640 480 16
        timings 40000 160 2 9 0 2 45
        accel false
        rgba 5/11,6/5,5/0,0/0
endmode

I also tried to compile microwindows-0.91 (thinking that the problem is maybe 
solved in that version), but I got the following error messages:

Compiling nanox/srvclip.c ...
Compiling nanox/srvnet.c ...
Linking nano-X ...
/home/roni/microwindows-0.91/src/obj/engine/devdraw.o(.text+0x2774): In

function `GdTranslateArea':

collect2: ld returned 1 exit status

Could anybody please help me to solve this problem? It's very important!
Thank you very much!

The
problem is that the colors are weird on the screen. (I set
MWPF_TRUECOLOR0565
in the microwindows config file and set the framebuffer for 16bpp


We need more description of "wierd" in order to understand
exactly how the color/bytes per pixel is mismatched on your system,
versus created by nano-X, thus drawing bits that show other than intended.



: undefined reference to `COLORVALTOPIXELVAL'
: undefined reference to `PIXELVALTOCOLORVAL'

This is because you used MWPF_TRUECOLOR0565, rather
than MWPF_TRUECOLOR565.  (added a '0', note comment
in config file)

Hi Greg, 

thank you for your answer! 
My second problem (compiling mw-0.91) is solved, thanks! But my original 
problem with the colors still exists. I figured out from pxa270 manual, that 
the LDD<0:17> pin color mappings change with the color depth. :-(
Now I have to change the connection between the board and the LCD. When I'm 
ready I'll infrom you about the situation. 
Thank you very much for your help again!
