Hello,
I am using ecos (20050912 with patches from Freescales).
I have generated a const struct with an image from GIMP (with "c code
source" filter) . Its size is 34.981 bytes (when size is 40.189 bytes it
is also working). The board boots correctly and I can display image data
to LCD.
If I increase image size, the structure grows up to 64.909 bytes. In
this case, board does not boot (no ++, nothing).
Here is the structure declaration (biglogo.h) of working image :
static const struct {
unsigned int width;
unsigned int height;
unsigned int bytes_per_pixel; /* 3:RGB, 4:RGBA */
unsigned char pixel_data[94 * 124 * 3 + 1];
} biglogo = {
94, 124, 3,
/* All RGB data */
}
and not working
static const struct {
unsigned int width;
unsigned int height;
unsigned int bytes_per_pixel; /* 3:RGB, 4:RGBA */
unsigned char pixel_data[128 * 169 * 3 + 1];
} biglogo = {
128, 169, 3,
/* All RGB data */
}
8 blocks of 128KByte are erased in Flash before writing new bin file and
verifying is also correct.
When it it working, bin file (complete builded ecos binary) has a size
of 250.668 bytes. When it is not working, bin file has a size of 310.524
bytes.
Is there some values in configurations files (cdl, ecm, db) where a
memory limit is set ?
Thanks a lot for your help.
Best regards,
GaÃtan.
