335x uboot-2018 logo

请参考下面的wiki网站
software-dl.ti.com/.../Foundational_Components_U-Boot.html

参考上边的文档移植，弄了一下午还没弄好额。。。系统启动的时候卡在：

[LCD] Initializing LCD frambuffer at 8ffb0000

最后一行打印是我加的，代码位置在common/lcd.c文件中的
static int lcd_init(void *lcdbase)
{
printf("[LCD] Initializing LCD frambuffer at %p\n", lcdbase);
lcd_ctrl_init(lcdbase);

/*
* lcd_ctrl_init() of some drivers (i.e. bcm2835 on rpi) ignores
* the 'lcdbase' argument and uses custom lcd base address
* by setting up gd->fb_base. Check for this condition and fixup
* 'lcd_base' address.
*/
if (map_to_sysmem(lcdbase) != gd->fb_base)
lcd_base = map_sysmem(gd->fb_base, 0);

debug("[LCD] Using LCD frambuffer at %p\n", lcd_base);

lcd_get_size(&lcd_line_length);
lcd_is_enabled = 1;
lcd_clear();
lcd_enable();

/* Initialize the console */
lcd_set_col(0);
#ifdef CONFIG_LCD_INFO_BELOW_LOGO
lcd_set_row(7 + BMP_LOGO_HEIGHT / VIDEO_FONT_HEIGHT);
#else
lcd_set_row(1); /* leave 1 blank line below logo */
#endif

return 0;
}

理了理，感觉嵌套越来越深了。。。。还没解决。。。
