u boot下自動升級使用手冊移植說明

任何明示或默示的或保證。 市龍崗區(qū)坂田電氣生產(chǎn) ubootUSBSD卡升級的使用和移植，主要包括升級包的制作、USB下自動升級、USB下手動升級、SD卡自動升級、SD卡手動升級以及相關(guān)的-包含Hi3518A--------

添加Hi3531AU-boot下系統(tǒng)升級使用說 U-boot下系統(tǒng)升級移植說 U-boot含有有效升級包則直接使用SD卡中的升級包升級系統(tǒng)，不再掃描U盤中的內(nèi)容。修改配置文件，開啟升級開關(guān) 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 步驟2.制作系統(tǒng)升級包uImage把升級包放在U盤中，U盤進行升級操作即可，這里不再舉例。*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，關(guān)于uboot編譯的信息，請查看《Hi3516A/Hi3516DU-boot移植應(yīng)用開發(fā)指南》。ubootu-boot-3516a-update.binU-1.Ubootmkimage-Aarm-Tfirmware-Cnone-nhiboot-du-boot-hi3516a.binu-u-boot-hi3516a.binhi3516au-boot鏡像，可以是不具備升級功能的u-boot也可以是支持自動升級的u-boot。2.Kernelkernel3.Rootfsmkimage-Aarm-Tfilesystem-Cnone-nhirootfs-drootfs_256k.jffs2體方法請參考《設(shè)備驅(qū)動操作指南.doc》附錄。readingu- readingu- flash flash readingkernelreadingkernelflasherase...flashreadingrootfsreadingrootfsflasherase...flashErasingSPIflash,offset0x00080000size256KWritingtoSPIflash,offset0x00080000size256KSDUSD卡中不含有升級包或者升級包無效時，系統(tǒng)將自動掃描U盤中的升級包進行系統(tǒng)升級。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 添加該文件在Flash上的位有兩種方法可以指定升級時各鏡像存放在Flash上的位置：在代碼中指定和在環(huán)境變量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");當(dāng)前環(huán)境變量中設(shè)置有”appst”和”appnd”時升級位置將按照環(huán)境變量中設(shè)置的位置升級系統(tǒng)，否則按照中代碼的設(shè)置值升級。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說明:APP升級鏡像時用mkimage加入校驗信息時建議采用’Tfilesystem’這個參下面以Hi3516A為例，完整移植自動升級功能到新平臺，新平臺可參考移FAT文件系統(tǒng)、MMC驅(qū)動、USBOHCI驅(qū)動移植后的操作請先保證在海思發(fā)布的U-boot版本下或者已完整移植好上述三部分驅(qū)動的U-boot版本。此三部分的具體移植詳見《U-bootU盤SD卡自動升級功能設(shè)計說明》。*sdcard/usbstoragesystem #defineCONFIG_AUTO_UPDATE 此行則關(guān)閉系統(tǒng)自動升級功能*/#ifdef#define #define 111**#ifdef#define
