Hello Greg,
Thanks for the reply.

Yes the config file is fully declared, and is nearly identical to the 0.91
config. The only differences are a consequence of change in the file itself.
To wit;
SCREEN_PIXTYPE = MWPF_TRUECOLOR565

I'm using:
lcd_win = GrNewWindow(GR_ROOT_WINDOW_ID, 0, 0, LCD_WIDTH_V(),
LCD_HEIGHT_V(), 0, GRAY, BLACK);
GrMapWindow(lcd_win);
pix_map = GrNewPixmap(LCD_WIDTH_V(), LCD_HEIGHT_V(), NULL);
text_gc = GrNewGC();
rect_gc = GrNewGC();
etc..
GrCreateFont((GR_CHAR *) "arialb12.fnt", 0, NULL);
GrSetGCForeground(gc, fg_col);
GrSetGCBackground(gc, bg_col);
GrText(win, gc, x, y, text, strlen(text), GR_TFTOP);
GrCopyArea(lcd_win, pix_gc, x, y, w, h, pix_map, x, y, MWROP_COPY);
GrFillRect(win, gc, x, y, w, (h));
to mainly draw white text in black rectangles, with popup rectangles of blue
boarders, white centers, black text.
the screen name is a red rectangle with white text.
Most of the screen is black.

Yes background and foreground fills work, as does drawing text, it is only the
color which is off, red is "a green",blue is light blue is pink, white is dim
and grey-blueish.

fbset gives:
mode "240x320-0"
# D: 0.000 MHz, H: 0.001 kHz, V: 0.003 Hz
geometry 240 320 240 320 16
timings -1 -1 -1 -1 -1 -1 -1
rgba 5/11,6/5,5/0,0/0
endmode
the driver is set with:
/* IPU Pixel format definitions */
/* Four-character-code (FOURCC) */
#define fourcc(a, b, c, d)\
(((__u32)(a)<<0)|((__u32)(b)<<8)|((__u32)(c)<<16)|((__u32)(d)<<24))
#define IPU_PIX_FMT_RGB565 fourcc('R', 'G', 'B', 'P') /*!< 1 6 RGB-5-6-5 */
static void mxcfb_init_panel (struct fb_info *fbi)
{
uint32_t pix_fmt = IPU_PIX_FMT_RGB565;
And all of this remains the same when I load the old 0.91 nano-X binary, and it
will be OK.
(to be clear I can rebuild the 0.91 code in the same toolchain and it is fine,
not a build tool issue)
Thanks,

What did you set MWPF_PIXELFORMAT to in the config file?
The above is supposed to be set in config only, not mwtypes.h.

These mods are in GdTranslateArea, which IIRC isn't actually
called or used.

What exactly is drawing those colors? Are you drawing images, or text,
or pure background colors? I'm trying to understand the engine routines
called, image, fillrect, or text.
I'm not sure what the problem is yet. It would be interesting to know
whether solid background fills work, (many demos do this), as well
as text or line draw colors, or whether the problem is just when
drawing images. The image drawing routines have changed greatly,
and use convblit functions which may need changing. Older
point-by-point drawing can be done by setting convblit = NULL
in GdDrawImage for instance, which will force the older slow methods.
What is the exact layout of your truecolor framebuffer, for each 16 bit
word?
Regards,
Greg
Simply reload my 0.91 build will correct the color problem.
I have hunted around but I seem alone on this one, the PSD struct members
appear to be the same settings on each build, as they should be:
92b
psd->xres, psd->yres, psd->ncolors, psd->data_format, type, visual,
psd->bpp);
240x 320x 65536 x80000 0 2 16
psd->xres, psd->yres, (psd->pixtype == MWPF_TRUECOLOR555)? 15: psd->bpp,
psd->pitch, type, visual, psd->ncolors, psd->pixtype);
240x 320x 16
480 0 2 65536 5
91
psd->xres, psd->yres, psd->ncolors, psd->linelen, type, visual, psd->bpp);
240x 320x 65536 480 0 2 16
psd->xres, psd->yres, (psd->pixtype == MWPF_TRUECOLOR555)? 15: psd->bpp,
psd->pitch, type, visual, psd->ncolors, psd->pixtype);
240x 320x 16bpp
0 2 65536 5
Any clues?
