Silent uboot on bootup #35

Closed motters closed 5 years ago

motters commented 5 years ago

U-Boot displays messaged on bootup which we dont want to see.

In file common/console.c variable CONFIG_SILENT_CONSOLE is used to disable console prints.

Add the following in include/config/rpi.h

/* Silent */
#define CONFIG_DISABLE_CONSOLE
#define CONFIG_SILENT_CONSOLE
#define CONFIG_SYS_DEVICE_NULLDEV
#define CONFIG_SILENT_CONSOLE_UPDATE_ON_RELOC
#define CONFIG_EXTRA_ENV_SETTINGS \ 
                      "silent=1\0" \

Next create a patch and append to SRC in uboot 

git diff > 010_Silent-boot.patch

This variable should be set but this is how u set in once booted 

fw_setenv silent yes

If the above does not work edit board/raspberrypi/rpi/rpi.c and add the below

#ifdef CONFIG_BOARD_EARLY_INIT_F
int board_early_init_f(void)
{
    gd->flags |= (GD_FLG_SILENT | GD_FLG_DISABLE_CONSOLE);
    return 0;
}
#endif

Then add the below to include/config/rpi.h

#define CONFIG_BOARD_EARLY_INIT_F
