#######################################UBOOT 2009.11版#############################################################
下载地址
http://ftp.denx.de/pub/u-boot/cd /mnt/mydrives/u-boot-1.3/u-boot-2009.11/
所以先修改Makefile
找到
ifeq ($(ARCH),arm)
CROSS_COMPILE = arm-linux-
endif
修改成
#CROSS_COMPILE = arm-linux-
CROSS_COMPILE = /home/zhh/arm-softfloat-linux-gnu/bin/arm-softfloat-linux-gnu-
endif
我的目录是/usr/local/arm/4.4.3/arm-linux- 可以在/etc目录里是之environment 添加arm-linux- 路径
实验了多种ARM-linux 均可以编译成功 所以采用此版本 实现了800x600 UBOOT开机显示LOGO
########################################at91sam9263ek.h 添加代码如下#################################################
Bootstrap-v1.14- /mnt/mydrives/Bootstrap-v1.14-knh/board/at91sam9263ek/nandflash/at91sam9263ek.h 添加代码如下
#define IMG_ADDRESS 0x20000 /* Image Address in NandFlash */
#define IMG_SIZE 0xB0000 /* Image Size in NandFlash */
因为新编译的uboot.bin 太大了有670多K 所以要修改参数IMG_SIZE 否则uboot不能正常启动
