Tshooj 4 BSP Source Guide
Tshooj lus no tau mob siab rau rau cov kws tshaj lij software tshwj xeeb los tsim BSP qhov chaw. Cov ntsiab lus hais hauv tshooj no yog raws li nram no:
- Kev npaj
- Lub tsev tso tawm
- Txhim kho qhov tso tawm rau lub rooj tsavxwm
4.1 Tsim BSP Source
4.1.1 Kev npaj
Qhov pom zoo tsawg kawg nkaus Ubuntu version yog 18.04 lossis tom qab ntawd.
1) Txhim kho cov pob khoom tsim nyog ua ntej tsim:
sudo apt-mus nruab gawk wget git-core diffstat unzip texinfo gcc-multilib \
tsim-tseem ceeb chrpath socat cpio python python3 python3-pip python3-pexpect \
xz-utils debianutils iputils-ping python3-git python3-jinja2 libegl1-mesa libsdl1.2-dev \
pylint3 xwm
2) Donwload toolchain
Cov clang siv los sau cov Linux ntsiav yuav tsum yog qhov tshiab dua. Ua cov kauj ruam hauv qab no los teeb tsa cov clang siv los suav Linux ntsiav: sudo git clone https://android.googlesource.com/platform/prebuilts/clang/host/linux-x86 /opt/ prebuiltandroid-clang -b master cd /opt/prebuilt-android-clang
sudo git checkout 007c96f100c5322acc37b84669c032c0121e68d0 export CLANG_PATH=/opt/prebuilt-android-clang
Cov lus txib xa tawm ua ntej tuaj yeem muab ntxiv rau "/etc/profile”. Thaum tus tswv boots,
"AARCH64_GCC_CROSS_COMPILE" thiab "CLANG_PATH" raug teeb tsa thiab tuaj yeem siv ncaj qha.
乙 、 Npaj tsim ib puag ncig rau U-Boot thiab Linux ntsiav.
Cov kauj ruam no yog qhov yuav tsum tau ua vim tsis muaj GCC cross-compile cov cuab yeej hauv ib qho hauv AOSP codebase.
ib. Download tau cov cuab yeej saw rau A-profile architecture ntawm caj npab Developer GNU-A Downloads nplooj. Nws raug pom zoo
siv 8.3 version rau qhov kev tso tawm no. Koj tuaj yeem rub tawm "gcc-arm-8.3-2019.03-x86_64-aarch64- elf.tar.xz" lossis "gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu.tar.xz". Thawj qhov yog mob siab rau muab cov kev pabcuam liab qab-hlau, thiab qhov thib ob kuj tuaj yeem siv los sau cov ntawv thov kev pabcuam.
b. Decompress lub file mus rau hauv txoj kev ntawm lub zos disk, example, to "/opt/". Export ib tug kuj muaj npe hu ua "AARCH64_GCC_CROSS_COMPILE" los taw tes rau lub cuab tam raws li hauv qab no:
# yog "gcc-arm-8.3-2019.03-x86_64-aarch64-elf.tar.xz" yog siv sudo tar -xvJf gcc-arm-8.3-2019.03-x86_64-aarch64-elf.tar.xz -C /opt
export AARCH64_GCC_CROSS_COMPILE=/opt/gcc-arm-8.3-2019.03-x86_64-aarch64-elf/bin/aarch64-elf-
# yog "gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu.tar.xz" yog siv sudo tar -xvJf gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu.tar.xz -C /opt export AARCH64_GCC_CROSS_COMPILE=/opt/gcc-arm-8.3-2019.03-x86_64-aarch64-linuxgnu/bin/aarch64-linux-gnu
3) Decompress IBR215 qhov chaw file (example ibr215-bsp.tar.bz2) rau hauv "/home/" folder.
