hi, all
I am writing a gfxdriver for Fujitsu mb86296 video card under DirectFB. When
I run a example df_fire from DirectFB-examples-1.0.0.tar.gz, there is no
output on the computer screen, it is black completely, and the error result
looks like this:
sh-3.00# ./df_fire

I wonder if it is wrong in my code in mb86296_screen.c which I refer to
sh7722 gfxdriver, here is the code:
/**********************************************************************************************************************/
static DFBResult
mb86296InitScreen( CoreScreen *screen,
CoreGraphicsDevice *device,
void *driver_data,
void *screen_data,
DFBScreenDescription *description )
{
/* Set the screen capabilities. */
description->caps = DSCCAPS_NONE;
/* Set the screen name. */
snprintf( description->name, DFB_SCREEN_DESC_NAME_LENGTH, "MB86296
Screen" );
return DFB_OK;
}
static DFBResult
mb86296GetScreenSize( CoreScreen *screen,
void *driver_data,
void *screen_data,
int *ret_width,
int *ret_height )
{
*ret_width = MB86296_LCD_WIDTH;
*ret_height = MB86296_LCD_HEIGHT;
return DFB_OK;
}
ScreenFuncs mb86296ScreenFuncs = {
InitScreen: mb86296InitScreen,
GetScreenSize: mb86296GetScreenSize
};
In driver_init_driver(), I called dfb_screens_register( device, driver_data,
&mb86296ScreenFuncs ).
anybody can help me??
