skyeye模拟器使用—模拟s3c2410的uboot启动

一、硬件配置

1.s3c2410.conf

# skyeye config file for S3C2410Xarch:armcpu: arm920tmach: s3c2410x# physical memorymem_bank: map=M, type=RW, addr=0x00000000, size=0x00100000mem_bank: map=M, type=RW, addr=0x30000000, size=0x04000000# all peripherals I/O mapping areamem_bank: map=I, type=RW, addr=0x48000000, size=0x20000000mem_bank: map=I, type=RW, addr=0x19000300, size=0x00000020uart:mod=termdbct:state=on

2.s3c2440.conf

#skyeye config file samplecpu:  arm920tmach: s3c2440#physical memory#mem_bank: map=M, type=RW, addr=0x20000000, size=0x01000000mem_bank: map=M, type=RW, addr=0x30000000, size=0x00800000mem_bank: map=M, type=RW, addr=0x30800000, size=0x00800000, file=./initrd.imgmem_bank: map=M, type=RW, addr=0x31000000, size=0x01000000#all peripherals I/O mapping area#mem_bank: map=I, type=RW, addr=0xfefa0000, size=0x00060000mem_bank: map=I, type=RW, addr=0x48000000, size=0x20000000mem_bank: map=I, type=RW, addr=0x19000300, size=0x00000020#net: type=cs8900a, base=0x19000300, size=0x20,int=9, mac=0:4:3:2:1:f, ethmod=tuntap, hostip=10.0.0.1lcd:type=s3c2440,mod=gtkload_addr:base=0x30000000, mask=0xFFFFFF#dbct:state=on

二、uboot下载编译

1.uboot下载

ftp://ftp.denx.de/pub/u-boot/

2.交叉编译工具链下载

http://ishare.iask.sina.com.cn/f/13836544.html

解压上述交叉编译工具

3.配置环境变量

gedit ~/.bashrc添加如下：

export PATH+=:/home/lianxi/skyeye/opt/FriendlyARM/toolschain/4.4.3/bin/

立即生效：

source ~/.bashrc

2.编译uboot

make distcleanmake smdk2410_configmake all

三、运行

cp u-boot-2011.12/u-boot ./ubootskyeye -e uboot -c s3c2410.conf 

报错：

DRAM:  64 MiBWARNING: Caches not enabledFlash: *** failed ***### ERROR ### Please RESET the board ###

修改：gedit drivers/mtd/cfi_flash.c

unsigned long flash_init (void){  unsigned long size = 0;  int i;

为

unsigned long flash_init (void){  unsigned long size = 1<<20;  int i;

重新编译uboot后运行：

skyeye -e uboot -c s3c2410.conf 

结果：
