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 S3C2410X arch:arm cpu: arm920t mach: s3c2410x # physical memory mem_bank: map=M, type=RW, addr=0x00000000, size=0x00100000 mem_bank: map=M, type=RW, addr=0x30000000, size=0x04000000 # all peripherals I/O mapping area mem_bank: map=I, type=RW, addr=0x48000000, size=0x20000000 mem_bank: map=I, type=RW, addr=0x19000300, size=0x00000020 uart:mod=term dbct:state=on2.s3c2440.conf
#skyeye config file sample cpu: arm920t mach: s3c2440 #physical memory #mem_bank: map=M, type=RW, addr=0x20000000, size=0x01000000 mem_bank: map=M, type=RW, addr=0x30000000, size=0x00800000 mem_bank: map=M, type=RW, addr=0x30800000, size=0x00800000, file=./initrd.img mem_bank: map=M, type=RW, addr=0x31000000, size=0x01000000 #all peripherals I/O mapping area #mem_bank: map=I, type=RW, addr=0xfefa0000, size=0x00060000 mem_bank: map=I, type=RW, addr=0x48000000, size=0x20000000 mem_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=10.0.0.1 lcd:type=s3c2440,mod=gtk load_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 distclean make smdk2410_config make all三、运行
cp u-boot-2011.12/u-boot ./uboot skyeye -e uboot -c s3c2410.conf报错：
DRAM: 64 MiB WARNING: Caches not enabled Flash: *** 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：
