s5pv210uboot-2012-10移植(一)之分析AlexLing的linaro-2011.
10formini210好久好久前就买了s5pv210的开发板,一直都是东搞搞西搞搞,一点收获也没有,这次下决心来移植最新的uboot到u-boot-2012.
10上,并通过这个博客记录下来以防时间长给忘了,我的开发板是QT210的.
s5pv210的启动分为BL0,BL1,BL2,BL0是出厂的时候就固化在IROM里的,所以我们的uboot就要实现BL1和BL2,BL1在uboot里叫做u-boot-spl.
bin,BL2就是我们很熟悉的u-boot.
bin了.
在移植之前,我们先看下AlexLing的linaro-2011.
10formini210的UBOOT是怎么实现的.
这里主要还是分析SPL部分,u-boot.
bin是如何生成的现在资料很多,也很复杂,我这个菜鸟也是一知半解的,所以就不分析了.
1.
顶层的Makefile,从中可以知道,我们要想生成u-boot-spl.
bin就必须配置COFNIG_SPL,那么u-boot-spl.
bin依赖什么呢,我们继续1.
ALL-$(CONFIG_SPL)+=$(obj)spl/u-boot-spl.
bin2.
3.
all:$(ALL-y)搜索发现,是进入到uboot顶层目录的spl目录下执行Makefile的1.
$(obj)spl/u-boot-spl.
bin:depend2.
$(MAKE)-Csplall2.
打开spl/Makefile分析,一开始就给我们导出CONFIG_SPL_BUILD1.
CONFIG_SPL_BUILD:=y2.
exportCONFIG_SPL_BUILD然后分析目标,因为我们的平台是三星的,所以,会有两个目标,一个是不带头信息的u-boot-spl.
bin,一个是$(obj)$(BOARD)-spl.
bin.
1.
ALL-y+=$(obj)u-boot-spl.
bin2.
3.
ifdefCONFIG_SAMSUNG4.
ALL-y+=$(obj)$(BOARD)-spl.
bin5.
endif6.
7.
all:$(ALL-y)搜索$(obj)$(BOARD)-spl.
bin,发现,他是通过一个工具生成带头信息的u-boot-spl.
binObject1Object2Object3Object4Object5Object6Object7Object8Object9Object10Object11Object12Object13Object14Object15Object16Object17Object18Object19Object20Object21Object22Object23Object24Object25Object26Object27Object28Object29Object30Object31Object32Object33Object34Object35Object36Object37Object38Object39Object40Object41Object42Object43Object44Object45Object46Object47Object48Object49Object50Object51Object52Object53Object54Object55Object56Object571.
ifdefCONFIG_SAMSUNG2.
$(obj)$(BOARD)-spl.
bin:$(obj)u-boot-spl.
bin3.
$(TOPDIR)/board/$(BOARDDIR)/tools/mk$(BOARD)spl.
exe\4.
$(obj)u-boot-spl.
bin$(obj)$(BOARD)-spl.
bin5.
endif好了,Makefile就分析到这里,知道了BL1是如何生成的了.
下面里分析代码了.
首先分析arch/arm/cpu/armv7/start.

bicsp,sp,#7/*8-bytealignmentforABIcompliance*/20.
ldrr0,=0x0000000021.
blboard_init_f其中,cpu_init_crit中主要做初始化了memory和串口,接下来就是调用C函数board_init_f了,在调用C函数之前得设置栈,board_init_f有两个,一个是在arch/arm/lib/board.
c,一个在board/samsung/mini210/mmc_boot.
c那么道理是那个呢,看各个目录下的Makefile1.
arch/arm/lib/下的1.
ifndefCONFIG_SPL_BUILD2.

endif2.
board/samsung/mini210/1.
ifdefCONFIG_SPL_BUILD2.
COBJS+=mmc_boot.
o3.
endif得出,是board/samsung/mini210/mmc_boot.
c了,打开1.
voidboard_init_f(unsignedlongbootflag)2.
{3.
__attribute__((noreturn))void(*uboot)(void);4.
copy_uboot_to_ram();5.
6.
/*JumptoU-Bootimage*/7.
uboot=(void*)CONFIG_SYS_TEXT_BASE;8.
(*uboot)();9.
/*NeverreturnsHere*/10.
}得出,首先拷贝BL2完整的UBOOT到RAM里去,然后从ram里开始执行,然后就没有了.
那么是如何拷贝的呢,这就得需要一个文档了S5PV210_iROM_ApplicationNote_Preliminary_20091126.
pdf中好了,看看copy_uboot_to_ram代码1.
typedefu32(*copy_sd_mmc_to_mem)2.
(u32channel,u32start_block,u16block_size,u32*trg,u32init);1.
ch=*(volatileu32*)(0xD0037488);2.
copy_sd_mmc_to_memcopy_bl2=3.
(copy_sd_mmc_to_mem)(*(u32*)(0xD0037F98));1.
u32ret;2.
if(ch==0xEB000000){3.
ret=copy_bl2(0,MOVI_BL2_POS,MOVI_BL2_BLKCNT,4.
CONFIG_SYS_TEXT_BASE,0);5.
}elseif(ch==0xEB200000){6.
ret=copy_bl2(2,MOVI_BL2_POS,MOVI_BL2_BLKCNT,7.
CONFIG_SYS_TEXT_BASE,0);8.
}其中,MOVI_BL2_POS是1,MOVI_BL2_BLKCNT是49,CONFIG_SYS_TEXT_BASE是uboot在内存里的其实地址.
复制完成之后就会在内存里从u-boot.
bin的start.
S出开始重新执行了.
s5pv210uboot-2012-10移植(二)之能够启动进入控制台这次我们将从官网下载的最新uboot-2012-10移植到s5pv210开发板上,让其进入控制台,效果如下:首先,我暂时没采用内核的SPL,这个将在后面给补上,这里的BL1是我自己参考资料写的,我用的是QT210开发板,内存1G,对于不同的开发板,需要重新配置memory和修改uboot在内存里的地址,也就是CONFIG_SYS_TEXT_BASE.
我的BL1代码在这里下载.
一、添加smdkv210单板1.
cp-aboard/samsung/smdkc100board/samsung/smdkv2102.
cpinclude/configs/smdkc100.
hinclude/configs/smdkv210.

vimboards.
cfg,在270行添加1.
270smdkv210armarmv7smdkv210samsungs5pc1xx4.
makesmdkv210_config可以生成u-boot.
bin了二、让u-boot.
bin在内存里启动起来1.
分析我的BL1代码可以得知,只拷贝了u-boot.
bin,并没有清楚bss,在lsarch/arm/cpu/armv7/start.
S+126中添加1.

s5pv210uboot-2012-10移植(六)之支持NandFlash我的开发板上外接256M的K9F2G08U0AFLASH芯片.
uboot-2012-10本身不带s5pv210的nandflash操作,s5pv210的nandflash和s3c2410的寄存器差不多,所以,我就在s3c2410的nandFlash上进行修改了,因为我不懂nandflash的HW_EEC,所以我实现的是SOFT_EEC了.

s5pv210uboot-2012-10移植(七)之支持SD卡我其实对SD卡的操作不是很熟悉,所以移植的肯定有问题,在随机赠送的Kingston4G的SD卡上可以进行读写,但是我换了张2G的SD卡,就不行了,原因暂时先不找了,等熟悉了SD卡的操作再看看,哪位大侠知道怎么移植的一定要告诉我,不胜感激.

make,使用命令烧入SD卡里,启动开发板s5pv210uboot-2012-10移植(八)之支持SD卡保存环境变量本次将实现SD卡保存环境变量,uboot的移植先到这里告一段落了,大体上能用了,但是还很不完善,等到以后需要用到的时候在继续添加,而且中间有移植错误的地方也希望各位大侠给指出来,特别是SD卡那里.

好了,make一下,烧写到SD卡里,上电出现***Warning-badCRC,usingdefaultenvironment,修改环境变量,保存,重新开机,然后看看有没有保存.
