Chitsauko 3 Software Setup
Ichi chitsauko chinosuma zvinotevera kuseta pachishandiso: (yevashandisi vepamusoro chete)
- Gadzira kudzoreredza SD kadhi
- Simudzira firmware kuburikidza nekudzorera SD kadhi
3.1 Gadzira Kudzoreredza SD Kadhi
Ongorora: Izvi ndezvevashandisi vepamberi vane IBASE yakajairika mufananidzo file chete.
Chaizvoizvo, IBR215 inofanorongedzerwa neOS (Android kana Yocto) kupinda eMMC nekukasira. Batanidza iyo HDMI ne IBR215, uye 12V-24V simba zvakananga.
Ichi chitsauko chinokutungamira iwe kugadzira yekudzoreredza boot-up microSD kadhi.
3.1.1 Kugadzirira iyo Recovery SD kadhi kuisa Linux / Android mufananidzo muEMMC
Ongorora: Yese data muEMMC ichadzimwa.
1) System zvinodiwa:
Operating System: Windows 7 kana gare gare Chishandiso: uuu SD kadhi: 4GB kana yakakura muhukuru
2) Isa kadhi rako reSD pabhodhi iri (kureva P1 yekubatanidza), batanidza bhodhi kuPC kuburikidza ne mini-USB port (kureva P4 yekubatanidza), uye shandura bhutsu modhi yekudhawunirodha.
3) boot IBR215 uye flash SD kuburikidza neCMD raira "uuu.exe uuu-sdcard.auto" kana kaviri kudzvanya "FW_down-sdcard.bat" (Same nzira sePCBA update)
3.1.2 Simudzira Firmware kuburikidza neRecovery SD Card
1) Isa kupora files mu USB flash disk (FAT32)
A> Yocto / Ubuntu: Kopa zvese kupora files muPATH:
2) Bairira (nhanho1)SD uye (nhanho2)USB flash disk muIBR215
3) Normal boot IBR215 (SW1 Pin1 OFF), tanga kupora eMMC pakarepo.
4) Ruzivo rwekuvandudza rucharatidza paHDMI.
Chitsauko 4 BSP Source Guide
Ichi chitsauko chakatsaurirwa kune epamberi software mainjiniya chete kuvaka BSP sosi. Misoro iri muchitsauko chino ndeiyi:
- Kugadzirira
- Kuburitswa kwekuvaka
- Kuisa kuburitswa kubhodhi
4.1 Kuvaka BSP Source
4.1.1 Kugadzirira
Iyo yakakurudzirwa shoma Ubuntu vhezheni ndeye 18.04 kana gare gare.
1) Isa mapakeji anodiwa usati wavaka:
sudo apt-tora kuisa gawk wget git-core diffstat unzip texinfo gcc-multilib \
kuvaka-yakakosha chrpath socat cpio python python3 python3-pip python3-tarisiro \
xz-utils debianutils iputils-ping python3-git python3-jinja2 libegl1-mesa libsdl1.2-dev \
pylint3 xterm
2) Dhawunirodha toolchain
Iyo clang inoshandiswa kuunganidza Linux kernel inoda kuve vhezheni nyowani. Ita matanho anotevera kuseta clang kuti ishandiswe kuunganidza Linux kernel: 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 kunze CLANG_PATH=/opt/prebuilt-android-clang
Iyo yakapfuura mirairo yekutumira kunze inogona kuwedzerwa ku "/etc/profile”. Kana muenzi asimuka,
"AARCH64_GCC_CROSS_COMPILE" uye "CLANG_PATH" akaiswa uye anogona kushandiswa zvakananga.
乙, Gadzirira nharaunda yekuvaka yeU-Boot uye Linux kernel.
Iyi nhanho inosungirwa nekuti hapana GCC muchinjika-kuunganidza chishandiso cheni mune imwe muAOSP codebase.
a. Dhawunirodha cheni yekushandisa yeA-profile zvivakwa pane ruoko Mugadziri GNU-A Downloads peji. Zvinokurudzirwa
kushandisa iyo 8.3 vhezheni yekuburitswa uku. Unogona kudhaunirodha "gcc-arm-8.3-2019.03-x86_64-aarch64- elf.tar.xz" kana "gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu.tar.xz". Yekutanga yakatsaurirwa kuunganidza isina-simbi zvirongwa, uye yechipiri inogona zvakare kushandiswa kuunganidza zvirongwa zvekushandisa.
b. Decompress the file mugwara riri padisiki remunharaunda, semuenzanisoample, ku "/ opt/". Tumira kunze shanduko ine zita rekuti "AARCH64_GCC_CROSS_COMPILE" kunongedza chishandiso sezvinotevera:
# kana “gcc-arm-8.3-2019.03-x86_64-aarch64-elf.tar.xz” inoshandiswa 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-
# kana "gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu.tar.xz" inoshandiswa sudo tar -xvJf gcc-arm-8.3-2019.03-x86_64-arch64-linux-gnu.tar.xz /sarudza kutumira kunze AARCH64_GCC_CROSS_COMPILE=/opt/gcc-arm-8.3-2019.03-x86_64-aarch64-linuxgnu/bin/aarch64-linux-gnu
3) Decompress iyo IBR215 sosi file (example ibr215-bsp.tar.bz2) kupinda "/home/" folda.

E. SD Card Test
Kana IBR210 yabviswa kubva eMMC, SD kadhi iri "/dev/mmcblk1" uye inokwanisa kuona ne "ls /dev/mmcblk1*" kuraira:
/dev/mmcblk1 /dev/mmcblk1p2 /dev/mmcblk1p4 /dev/mmcblk1p5 /dev/mmcblk1p6
Ongorora: Kuvhiya uku kunogona kukanganisa data rakachengetwa SD kadhi. Usati watanga bvunzo, ita shuwa kuti hapana yakakosha data muEMMC flash iri kushandiswa.
Verenga, nyora, uye tarisa
