The preboot command is run too late. It looks like it is run in
main_loop but U-Boot looks for the splash image
at the address in the splashimage variable in board_init_r -
stdio_init - drv_lcd_init or drv_video_init (depending on

What's the bug?
- preboot being called too late, or
preboot is not called too late. The behavior is correct and wanted, as
the name says, and the variable is evaluated during the main loop before
booting. My suggestion comes because it is possible to implement a
splashscreen (even if the name can be misleading..), setting preboot to
something like nand read address offset;bmp display address.
In your case (with a bmp image), it could be:
preboot=if sf probe ; then \
sf read ${splashimage} c2000 ${splashsize} ; bmp display
${splashimage}; fi\0
The behavior is exactly as the subject in the patch, the delay is from
power-on until main loop is called. It can be on some boards acceptable,
sometimes not.
- splash_screen_prepare() being called too early
It seems that having splash_screen_prepare() called early
makes sense, because stdout could be set to include VGA
and having access to stdout is very useful in preboot

You mention that it does not work, and then I assume that it is a bug,
because an image should be displayed. But again, if it does not work,
the issue is related to the video subsystem and should be fixed there
and not in board code - this is my point.

Gotcha. This method doesn't involve splash_screen_prepare() though.
It also will blink the display since the splash screen will paint
after the the compiled-in logo case.

Yes, as Eric mentioned I submitted a patch yesterday which fixes
splash screen prepare not working
with CONFIG_VIDEO and will submit a separate patch to add the function
to nitrogen6x.c once that goes through.
The only difference is that we won't call it in board_video_skip in
nitrogen6x.c, it'll be called in
drv_video_init similar to the way it is called in lcd_logo from drv_lcd_init.
Another thing that Eric pointed out that is a difference between
PREBOOT and SPLASH_SCREEN_PREPARE
is the former will always run but the latter will only run if there's
a display which is preferable.
If I had submitted the fix first instead of just working around the
bug I would probably have saved
some confusion. Sorry about that.
This works with Robert's latest patch, which implements

Which is the advantage instead of using the preboot variable setting
CONFIG_PREBOOT ? It does pretty the same and you can move the whole
script outside of board code.
The preboot command is run too late. It looks like it is run in
main_loop but U-Boot looks for the splash image
at the address in the splashimage variable in board_init_r -
stdio_init - drv_lcd_init or drv_video_init (depending on
whether you have CONFIG_LCD or CONFIG_VIDEO).
I have a patch ready that will fix the underlying problem with
CONFIG_SPLASH_SCREEN_PREPARE not working
for CONFIG_VIDEO so the nitrogen specific code (in a separate patch of
course) will change to use the provided callback instead of just
calling it in our own board_video_skip, but other than that it'll be
the same as the patch I already submitted.

Stefano Babic

I originally tried to use the CONFIG_SPLASH_SCREEN_PREPARE functionality.
After some frustration, I figured out that without CONFIG_LCD, it is never
actually called.
http://git.denx.de/?p=u-boot/u-boot-imx.git;a=blob;f=common/stdio.c;h=5d5117c0ed838195a2caad7c28c128247771cd92;hb=HEAD#l216
It does seem odd that there are 2 totally different paths and the other
splash screen related macros are used in both but the prepare function is
only called in the LCD case.
OK, so this is a bug that needs to be fixed - but for all boards.
Since we use CONFIG_VIDEO and not CONFIG_LCD, this seemed to be the best,
or at least the least invasive, solution.
No, this is definitely not the best solution, as it keeps the bug,
so the next one who tries to do what you are doing will run into it
again.
Pleast let's fix the problem at the cause.
Please fix the video code to also run splash_screen_prepare() at the
appropriate place. While you are at it, please also replace this
construct
1071 #ifdef CONFIG_SPLASH_SCREEN_PREPARE
1072 static inline int splash_screen_prepare(void)
1073 {
1074 return board_splash_screen_prepare();
1075 }
1076 #else
1077 static inline int splash_screen_prepare(void)
1078 {
1079 return 0;
1080 }
1081 #endif
(in common/lcd.c) and use a weak function for
splash_screen_prepare(). board_splash_screen_prepare() is no longer
needed, then (the boards can provide their own implementation of
splash_screen_prepare()).
Thanks.
Best regards,

I'm not quite clear on how it should be.
So if I were just fixing lcd.c to use a weak function it would look like this:
#ifdef CONFIG_SPLASH_SCREEN_PREPARE
int __splash_screen_prepare(void)
{
return 0;
}
int splash_screen_prepare(void)
__attribute__ ((weak, alias(__splash_screen_prepare)));
#endif
But it'd also have to go in cfb_console.c. Is it possible for a board
to ever use both CONFIG_LCD and CONFIG_VIDEO and if ?
Also are prototypes necessary? Looking at cfb_console for example
weak functions I see a prototype for video_set_lut in video_fb.h but I
can't find any for board_video_skip.
Thanks.

I originally tried to use the CONFIG_SPLASH_SCREEN_PREPARE functionality. After some frustration, I figured out that without CONFIG_LCD, it is never actually called. http://git.denx.de/?p=u-boot/u-boot-imx.git;a=blob;f=common/stdio.c;h=5d5117c0ed838195a2caad7c28c128247771cd92;hb=HEAD#l216 It does seem odd that there are 2 totally different paths and the other splash screen related macros are used in both but the prepare function is only called in the LCD case. Since we use CONFIG_VIDEO and not CONFIG_LCD, this seemed to be the best, or at least the least invasive, solution. What exactly cannot be done wioth the existing features? BTW: it would be nice if you flag board specific code in the Subject:, and it is considered mandatory to Cc: the respective board maintainer. I apologize for that. I'm new and didn't know till after I'd already sent it. I did CC the board maintainer, Eric. We also went over the code in person.
