Hi,
Frame buffer drivers in /src/drivers/fblin4.c are
for big endian. I modified fblin4.c for my SH little
endian. You have to check bit pixels in frame buffer.
See comments in source file(fblin4.c) I attached.
This is 4bpp display.
BigEndian (original fblin4.c)
32 16 15 0
-----------------------------------------
| P7 | P6 | P5 | P4 | P3 | P2 | P1 | P0 |
-----------------------------------------
LittleEndian (My SH3 target, attatched file, fblin4.c)
32 16 15 0
-----------------------------------------
| P0 | P1 | P2 | P3 | P4 | P5 | P6 | P7 |
-----------------------------------------
You'd better check how pixels are allocated in
your frame buffer memory.
Good Luck,
Kyoung Kim

Hi..
I succedded to excute 'mdemo' on SuperH .
But outputs is strange...
It seems that bitmaps is reversed.
I suspect there is a endian problerm...
Linux-sh is running little endian.
Is this a framebuffer driver bug or a microwindow bug ?
