: I have a LCD module with 5/6/5 packed pixel mode. It does not have direct
: access to its video ram. I have to fulush frame buffer content. When
: should I flush the frame buffer contents to lcd controller? I tried with
: ioctls which flushes line, pixel and rectangle from subdriver fblin16.c.
You should likely flush just before the select() routine is called
in nanox/srvmain.c.
: It seems working, but it does not display any text data or images...
Text data is displayed using the Blit driver function. You'll
need to have a flush routine handle that function as well.

Greg
