2，已知但未解决问题：NandManager均衡时存在copydate -6的报错，尚不清楚该报错对系统的具体影响。 3 *****为warrior增加了serial_no：TAB4780706AB|2013-07-16|贾磊 M bootable/bootloader/xboot/include/configs/warrior.h 4 *****修改了FASTBOOT|2013-07-19|贾磊 修改了fastboot的界面显示。 修改了进入fastboot模式的逻辑：使用返回键进入，等待5秒钟，未插入usb线缆则进入recovery模式。 在xboot中使用FAST_BOOT_SUPPORT确定是否支持fastboot。目前支持fastboot的板子有grus(800*480), mensa(8008480), warrior(1024*600), trooper(1024*600) 和npm801(1024*768)。 对于没有u盘功能的板子，增加CONFIG_NO_MASS_STORAGE。 M bootable/bootloader/xboot/Makefile M bootable/bootloader/xboot/boot/lcd/lcd.c M bootable/bootloader/xboot/boot/lcd/logo.c A
