问题描述

u_boot的logo显示问题，求大神帮忙看看，做的我心都碎了

u-boot目录下所有关于Logo的文件都有，网上搜了一些说要在配置文件里添加配置语句，添加如下
#define CONFIG_CMD_BMP
#define CONFIG_VIDEO
#define CONFIG_VIDEO_LOGO
#define CONFIG_VIDEO_BMP_LOGO
#define VIDEO_FB_16BPP_WORD_SWAP
结果报错如图

解决方案

应该就那几个关于 FB 的， 参考 readme：

• Console Interface:
  Depending on board, define exactly one serial port
  (like CONFIG_8xx_CONS_SMC1, CONFIG_8xx_CONS_SMC2,
  CONFIG_8xx_CONS_SCC1, ...), or switch off the serial
  console by defining CONFIG_8xx_CONS_NONE

          Note: if CONFIG_8xx_CONS_NONE is defined, the serial
          port routines must be defined elsewhere
          (i.e. serial_init(), serial_getc(), ...)
  
          CONFIG_CFB_CONSOLE
          Enables console device for a color framebuffer. Needs following
          defines (cf. smiLynxEM, i8042, board/eltec/bab7xx)

                                          (default big endian)

                                          (cf. smiLynxEM)
                  VIDEO_HW_BITBLT         graphic chip supports
                                          bit-blit (cf. smiLynxEM)
                  VIDEO_VISIBLE_COLS      visible pixel columns
                                          (cols=pitch)
                  VIDEO_VISIBLE_ROWS      visible pixel rows
                  VIDEO_PIXEL_SIZE        bytes per pixel
                  VIDEO_DATA_FORMAT       graphic data format
                                          (0-5, cf. cfb_console.c)
                  VIDEO_FB_ADRS           framebuffer address
                  VIDEO_KBD_INIT_FCT      keyboard int fct
                                          (i.e. i8042_kbd_init())
                  VIDEO_TSTC_FCT          test char fct
                                          (i.e. i8042_tstc)
                  VIDEO_GETC_FCT          get char fct
                                          (i.e. i8042_getc)
                  CONFIG_CONSOLE_CURSOR   cursor drawing on/off
                                          (requires blink timer
                                          cf. i8042.c)
                  CONFIG_SYS_CONSOLE_BLINK_COUNT blink interval (cf. i8042.c)
                  CONFIG_CONSOLE_TIME     display time/date info in
                                          upper right corner
                                          (requires CONFIG_CMD_DATE)
                  CONFIG_VIDEO_LOGO       display Linux logo in
                                          upper left corner
                  CONFIG_VIDEO_BMP_LOGO   use bmp_logo.h instead of
                                          linux_logo.h for logo.
                                          Requires CONFIG_VIDEO_LOGO
                  CONFIG_CONSOLE_EXTRA_INFO
                                          additional board info beside
                                          the logo
  
          When CONFIG_CFB_CONSOLE is defined, video console is
          default i/o. Serial console can be forced with
          environment 'console=serial'.
  
          When CONFIG_SILENT_CONSOLE is defined, all console
          messages (by U-Boot and Linux!) can be silenced with
          the "silent" environment variable. See
          doc/README.silent for more information.

解决方案四：

你还需要定义 CONFIG_CFB_CONSOLE

解决方案五：

就是这个cfb_console.c总是配不好，感觉要崩溃了，求大神解救啊
