BSP內核啟動 · 荔枝派Zero指南

# BSP內核 ## BSP內核剝離 BSP內核對攝像頭驅動支持較好，所以在攝像頭應用中有必要使用BSP內核。官方SDK中camdriod與lichee linux內核綁定，而camdriod比較龐大，所以我們只需抽取lichee linux內核，而拋棄camdriod代碼。單獨使用lichee linux的方法是：（構建走讀見本節附錄） 1. 解壓buildroot/dl/gcc-linarno.tar.gz 到lichee/out/sun8iw8p1/linux/common/buildroot/external-toolchain，并加入環境變量（這步其實在下一步里包含了） 2. 執行build_tiger-cdr.sh 編譯成功后，會顯示： ~~~ Image Name: Linux-3.4.39 Created: Thu Oct 5 03:05:06 2017 Image Type: ARM Linux Kernel Image (uncompressed) Data Size: 2275408 Bytes = 2222.08 kB = 2.17 MB Load Address: 40008000 Entry Point: 40008000 Image arch/arm/boot/uImage is ready 'arch/arm/boot/Image' -> 'output/bImage' 'arch/arm/boot/uImage' -> 'output/uImage' 'arch/arm/boot/zImage' -> 'output/zImage' Building modules compile Kernel successful ~~~ 主線uboot啟動bsp內核使用uimage。 ## BSP內核配置 BSP內核源碼在lichee/linux-3.4下。通過make ARCH=arm menuconfig來配置內核。我們可以使能攝像頭需要修改的一些內核配置：使能USB攝像頭驅動： ~~~ -> Device Drivers x -> Multimedia support (MEDIA_SUPPORT [=y]) x -> Video capture adapters (VIDEO_CAPTURE_DRIVERS [=y]) x -> V4L USB devices (V4L_USB_DRIVERS [=y]) x -><M> USB Video Class (UVC) CONFIG_USB_VIDEO_CLASS ~~~ 使能DVP/MIPI攝像頭 ~~~ -> Device Drivers x -> Multimedia support (MEDIA_SUPPORT [=y]) x -> Video capture adapters (VIDEO_CAPTURE_DRIVERS [=y]) x -> V4L platform devices (V4L_PLATFORM_DRIVERS [=y]) x -> SoC camera support (SOC_CAMERA [=y]) x x <M> ov2640 camera support x x <M> ov5647 camera support x x <M> sunxi video front end (camera and etc)driver x x <M> v4l2 driver for SUNXI <*> sunxi video encoder and decoder support ~~~ 由于camdriod原始的內核配置是為了在spi nor flash上運行而配置的，沒有ext4支持，所以需要額外添加ext4支持： ~~~ <*> The Extended 4 (ext4) filesystem x x [*] Use ext4 for ext2/ext3 file systems (NEW) x x [*] Ext4 extended attributes (NEW) x x [ ] Ext4 POSIX Access Control Lists (NEW) x x [ ] Ext4 Security Labels (NEW) x x [ ] EXT4 debugging support (NEW) x x [ ] JBD2 (ext4) debugging support (NEW) ~~~ 另外還要加上CONFIG_LBDAF（大文件支持，否則無法掛載文件系統） ~~~ -> Enable the block layer (BLOCK [=y]) [*] Support for large (2TB+) block devices and files ~~~ 再加上CGROUPS支持： ~~~ -> General setup [*] Control Group support ---> ~~~ 如果在文件系統（如debian）中使用了SWAP等特性，則還需要在內核中開啟SWAP。 debian下還需要開啟 FHANDLE 特性，否則會出現以下錯誤 ~~~ A start job is running for dev-ttyS0.device timeout ~~~ 如果需要使用wifi功能，則還需要勾選RTL8723BS的支持（注意需要選擇模塊方式），和AW_RF_PM選項。以及下節所說的fex修改。 ## uboot啟動BSP內核使用主線uboot啟動BSP內核，需要修改下啟動腳本，放入BSP內核需要的script.bin配置文件（相當于主線linux的dtb）修改boot.cmd: ~~~ setenv bootargs console=ttyS0,115200 panic=5 rootwait root=/dev/mmcblk0p2 earlyprintk rw setenv bootm_boot_mode sec setenv machid 1029 load mmc 0:1 0x41000000 zImage load mmc 0:1 0x41d00000 script.bin bootz 0x41000000 ~~~ 重新生成boot.scr: `mkimage -C none -A arm -T script -d boot.cmd boot.scr` 將boot.scr放入第一分區。再配置生成script.bin. 復制一份lichee/tools/pack/chips/sun8iw8p1/configs/tiger-cdr/sys_config.fex 修改其中的攝像頭配置：首先修改SD卡檢測策略，設置為不檢測，默認插入 `sdc_detmode=3` 使能RTL8723bs無線網卡的話，需要使能mmc1，也設置為不檢測sd卡。保存，并使用fex2bin sys_config.fex script.bin 生成script.bin文件。將script.bin也放入第一分區。然后需要配置uboot，取消**IMAGE_ENABLE_OF_LIBFDT**宏定義再將前面編譯的zImage放入第一分區。此時就可以使用主線Uboot啟動bsp內核了。 ## 附錄：BSP 內核構建走讀使用BSP內核的話，需要使用官方sdk編譯camdriod并從中取出uImage。鑒于camdriod較大，所以我們先簡單走讀下camdriod中對lichee的構建過程，扣出這部分內容。 camdriod的構建腳本： ~~~ #!/bin/bash source build/envsetup.sh && lunch && mklichee && extract-bsp && make -j8 && pack ~~~ source build/envsetup.sh 這里是include各種環境變量，比如就添加了tiger_cdr-eng選項，這里先不管它。 lunch就是選擇目標板配置了，是在build/envsetup.sh中的函數。接著就是關鍵的mklichee了，在device/softwinner/common/vendorsetup.sh里，深入看下：首先是一堆常量定義，放這里備查 ~~~ function set_environment() { LICHEE_CHIP="sun8iw8p1" export CAMLINUX_BUILD_TOP=`pwd` export DEVICE_DIR=$CAMLINUX_BUILD_TOP/device/softwinner export TARGET_OUT=$CAMLINUX_BUILD_TOP/output export OUT_DIR=$CAMLINUX_BUILD_TOP/out export LICHEE_DIR=$CAMLINUX_BUILD_TOP/../lichee export LICHEE_OUT_DIR=$LICHEE_DIR/out/sun8iw8p1/linux export BR_ROOTFS_DIR=$TARGET_OUT/target export LICHEE_BR_DIR=${LICHEE_DIR}/buildroot export LICHEE_KERN_DIR=${LICHEE_DIR}/linux-3.4 export LINUXOUT_MODULE_DIR=$LICHEE_KERN_DIR/output/lib/modules/*/* export LICHEE_KERN_OUTDIR=$LICHEE_KERN_DIR/output export LICHEE_TOOLS_DIR=${LICHEE_DIR}/tools export LICHEE_UBOOT_DIR=${LICHEE_DIR}/brandy/u-boot-2011.09 } ~~~ mklichee本體： ~~~ function mklichee() { mksetting #顯示目前的配置信息 mk_info "build lichee ..." mkbr && mkkernel # mkbr && mkkernel && mkuboot [ $? -ne 0 ] && return 1 return 0 } ~~~ mkbr是運行了 buildroot/scripts/build.sh buildroot linux sun8iw8p1 gcc-linaro.tar.bz2 ~~~ function mkbr() { mk_info "build buildroot ..." local build_script build_script="scripts/build.sh" LICHEE_PLATFORM="linux" (cd ${LICHEE_BR_DIR} && [ -x ${build_script} ] && ./${build_script} "buildroot" ${LICHEE_PLATFORM} ${LICHEE_CHIP}) [ $? -ne 0 ] && mk_error "build buildroot Failed" && return 1 mk_info "build buildroot OK." } ~~~ build.sh寫著： ~~~ if [ "x${LICHEE_PLATFORM}" = "xlinux" ] ; then build_buildroot export PATH=${LICHEE_BR_OUT}/external-toolchain/bin:$PATH build_external else build_toolchain ~~~ LICHEE_PLATFORM并沒有被傳入，實際執行的是build_toolchain： ~~~ build_toolchain() { local tooldir="${LICHEE_BR_OUT}/external-toolchain" mkdir -p ${tooldir} if [ -f ${tooldir}/.installed ] ; then printf "external toolchain has been installed\n" else printf "installing external toolchain\n" printf "please wait for a few minutes ...\n" tar --strip-components=1 \ -jxf ${LICHEE_BR_DIR}/dl/gcc-linaro.tar.bz2 \ -C ${tooldir} [ $? -eq 0 ] && touch ${tooldir}/.installed fi export PATH=${tooldir}/bin:${PATH} } ~~~ 這里LICHEE_BR_OUT是lichee/out/sun8iw8p1/linux/common/buildroot LICHEE_BR_DIR是lichee/buildroot, 需要先導入。這里使用的linaro版本比較老。注意如果使用較新的gcc反而會出錯。這里就是解壓了linaro-gcc，并加入到環境變量。 mkbr看完了，接下來看mkkernel。 function mkkernel() { local platformdef=$tdevice if [ ! -n $tdevice ]; then echo "Please lunch device" return 1 fi echo "Make the kernel" echo "platformdef="${platformdef} (cd ${LICHEE_KERN_DIR}/; ./build.sh -p ${platformdef}) [ $? -ne 0 ] && mk_error "build mkkernel fail" && return 1 echo "Make the kernel finish" return 0 } 執行的是lichee/linux-3.4/build.sh, 跟下去是執行了： ./scripts/build_${PLATFORM}.sh all 看script目錄下，有： ~~~ build_crane-cdr.sh build_crane-ipc.sh build_crane-sdv.sh build_crane-standard.sh build_rootfs.sh build.sh build_sun6i.sh build_sun8iw8p1.sh build_tiger-cdr.sh build_tiger-ipc.sh build_tiger-standard.sh ~~~ 就是代表的可以構建的板子型號。我們實際編譯的時候只需要執行build_tiger-cdr.sh 即可。綜上所述，需要剝離camdriod所用的lichee內核，只需要： 1. 解壓buildroot/dl/gcc-linarno.tar.gz 到lichee/out/sun8iw8p1/linux/common/buildroot/external-toolchain，并加入環境變量（這步其實在下一步里包含了） 2. 執行build_tiger-cdr.sh ## 啟動信息 ~~~ Starting kernel ...
