Thank you for clearing it out for me.
See also:
By adding the CFG_CMD_BMP option to your CONFIG_COMMANDS command selections you can enable support for bitmap images in U-Boot. This will add bmp to the list of commands in your configuration of U-Bootdoes not enable bmp command. I also tried with #define CONFIG_COMMANDS (CONFIG_CMD_DFL | CMD_BMP), but with no success.
Probably because it's CFG_CMD_BMP ?
Yes, I noticed.
Also be aware that so far only the MPC823 LCD driver ("cpu/mpc8xx/lcd.c") and the SMI LynxE driver ("drivers/cfb_console.c") actually implement bitmap support and the splash screen feature.
Also noticed that it doesn't compile for pxa - le{16,32}_to_cpu functions are missing and lcd_display_bitmap() is not defined. I included linux/byteorder/little_endian.h in pxafb.c and copied lcd_display_bitmap() from cpu/mpc8xx/lcd.c (did some quick hacks to get it compile), but with no luck.
I guess I should first try to get testpattern displayed using functions that are in pxafb.c already.
CONFIG_LCD_LOGO gets #undefined in pxafb.c by default, but I commented it out and am also including bmp_logo.h (instead of bmp_nexus.h). I'm suspecting that this gets u-boot corrupted since LCD is initialized at 0x0, [LCD] Initializing LCD frambuffer at 00000000
and bitmap_plot() writes to lcd_base pointed to 00000000.
further... I suspect there should be something similar done in lib_arm/board.c as in lib_ppc/board.c ?
... #ifdef CONFIG_LCD /* reserve memory for LCD display (always full pages) */ addr = lcd_setmem (addr); gd->fb_base = addr; #endif /* CONFIG_LCD */ ...
Function for reserving memory for fb - lcd_setmem() - already exist in pxafb.c but it doesn't seem to be used anywhere ?!
