nanogui: Thread: Color problem in big endian target

Hi,

 

I'm sure this has been asked before, but since there wasn't any search
function in archine I'll ask again.

 

I'm using Microwindows(or Nano-X) on Intel Xscale in big endian mode. It's
working fine except the colours are all wrong. What I've learn from the net
that this is because of the big endian mode. I tried every possible config
possibility, but they offered no help. Only change in colours I got when I
enabled palette mode, but even then the colours where wrong.

 

What I need to do to get the colours right? I'm running Linux and with the
X-server the colours are ok so I think the problem must be with the Nano-X.
Because Linux is running in big endian mode I cannot test the little endian
version to see if that solve anything.

 

Target has Frame buffer implemented and X-server is configured for 16-bit
colours if that helps anything.

 

Thanks.

Make sure you've configure nano-X for one of the two 16bpp
color options - 5/5/5 or 5/6/5.

If this doesn't solve your problem, then you might have to 
change the 555 or 565 color macros defined in include/mwtypes.h
to appropriately rearrange the bits in a 16-bit word from R,G,B
values.
