u boot下自动升级使用手册移植说明

任何明示或默示的或保证。 市龙岗区坂田电气生产 ubootUSBSD卡升级的使用和移植，主要包括升级包的制作、USB下自动升级、USB下手动升级、SD卡自动升级、SD卡手动升级以及相关的-包含Hi3518A--------

添加Hi3531AU-boot下系统升级使用说 U-boot下系统升级移植说 U-boot含有有效升级包则直接使用SD卡中的升级包升级系统，不再扫描U盘中的内容。修改配置文件，开启升级开关 lude/configs/hi3518ev200.h【hi3518ev200】lude/configs/hi3518ev201.h【hi3518ev201】lude/configs/hi3516cv200.h【hi3516cv200】lude/configs/hi3520d.h lude/configs/godcare.h lude/configs/godarm.h lude/configs/go lude/configs/hi3535.h lude/configs/hi3516a.h lude/configs/hi3516a lude/configs/hi3536.h和lude/configs/hi3536 lude/configs/ / lude/configs/hi3519.h和lude/configs/hi3519 步骤2.制作系统升级包uImage把升级包放在U盘中，U盘进行升级操作即可，这里不再举例。*sdcard/usbstoragesystem /*#defineCONFIG_AUTO_UPDATE 1*/#ifdefCONFIG_AUTO_UPDATE#define #define makeARCHarmCROSS_COMPILEarm-hisiv300-linux-hi3516a_configmakeARCHarmCROSS_COMPILEarm-hisiv300-linux--j./mkboot.shreg_info.binu-boot-3516a-mkboot.shreginfo.bin/Hi3516ASDKV/package/osdrv/tools/pc/uboottools/中，关于uboot编译的信息，请查看《Hi3516A/Hi3516DU-boot移植应用开发指南》。ubootu-boot-3516a-update.binU-1.Ubootmkimage-Aarm-Tfirmware-Cnone-nhiboot-du-boot-hi3516a.binu-u-boot-hi3516a.binhi3516au-boot镜像，可以是不具备升级功能的u-boot也可以是支持自动升级的u-boot。2.Kernelkernel3.Rootfsmkimage-Aarm-Tfilesystem-Cnone-nhirootfs-drootfs_256k.jffs2体方法请参考《设备驱动操作指南.doc》附录。readingu- readingu- flash flash readingkernelreadingkernelflasherase...flashreadingrootfsreadingrootfsflasherase...flashErasingSPIflash,offset0x00080000size256KWritingtoSPIflash,offset0x00080000size256KSDUSD卡中不含有升级包或者升级包无效时，系统将自动扫描U盘中的升级包进行系统升级。U-boot以下移植修改均在文件./product/hiupdate/autoupdate.c/*possiblenamesoffilesonthemedium.*/#defineAU_FIRMWARE"u-boot"#defineAU_KERNEL"kernel"#defineAU_ROOTFS"rootfs"#defineAU_APP"app"/*pointerstofilenames*/char*aufile[AU_MAXFILES]{/*indexofeachfileinthefollowingarrays*/#defineIDX_FIRMWARE #define #define #define /*max.numberoffileswhichcouldinterestus*/#defineAU_MAXFILES 添加该文件在Flash上的位有两种方法可以指定升级时各镜像存放在Flash上的位置：在代码中指定和在环境变量1./*layoutoftheFLASH.ST startaddress,ND endaddress.*/#defineAU_FL_FIRMWARE_ST #defineAU_FL_FIRMWARE_ND #defineAU_FL_KERNEL_ST #defineAU_FL_KERNEL_ND #defineAU_FL_ROOTFS_ST #define #define 0x…//Flash#define 0x……//Flash/*sizesofflashareasforeachfile*/longausize[AU_MAXFILES] (AU_FL_FIRMWARE_ND+1)-AU_FL_FIRMWARE_ST,(AU_FL_KERNEL_ND+1)-AU_FL_KERNEL_ST,(AU_FL_ROOTFS_ND+1)-AU_FL_ROOTFS_ST,(AU_FL_APP_ND+1)-/*arrayofflashareasstartandendaddresses*/structflash_layoutaufl_layout[AU_MAXFILES] { AU_FL_FIRMWARE_ND,{ { 2.doautoupdatevoid)*GetimagelayoutfromIfthestartaddress werenotdefinedinenvironmentusethedefaultget_update_env("firmware_st","firmware_nd");get_update_env("kernel_st","kernel_nd");get_update_env("rootfs_st","rootfs_nd");get_update_env("app_st","app_nd");当前环境变量中设置有”appst”和”appnd”时升级位置将按照环境变量中设置的位置升级系统，否则按照中代码的设置值升级。aucheckheadervalid(intidxlongnbytes)/*checkthetype-coulddothis giganticif()*/if((idx IDX_FIRMWARE)&&(hdr->ih_type!IH_TYPE_FIRMWARE)){printf("Image%swrongtype\n",aufile[idx]);return-1;}if IDX_KERNEL)&&(hdr->ih_type!{printf("Image%swrongtype\n",aufile[idx]);return-1;}if IDX_ROOTFS)(hdr->ih_type!IH_TYPE_RAMDISK)&&(hdr->ih_type!IH_TYPE_FILESYSTEM)){printf("Image%swrongtype\n",aufile[idx]); return-}if IDX_APP)&&(hdr->ih_type!{printf("Image%swrongtype\n",aufile[idx]); return-}mkimage说明:APP升级镜像时用mkimage加入校验信息时建议采用’Tfilesystem’这个参下面以Hi3516A为例，完整移植自动升级功能到新平台，新平台可参考移FAT文件系统、MMC驱动、USBOHCI驱动移植后的操作请先保证在海思发布的U-boot版本下或者已完整移植好上述三部分驱动的U-boot版本。此三部分的具体移植详见《U-bootU盘SD卡自动升级功能设计说明》。*sdcard/usbstoragesystem #defineCONFIG_AUTO_UPDATE 此行则关闭系统自动升级功能*/#ifdef#define #define 111**#ifdef#define
