3.2 Boot Instructions

  1. Once build is complete, prepare your eMMC binaries and images:
    1. Make a copy of the prebuilt-images directory to be used as a working directory for flashing.

    2. NOTE

    Review the <Android_FS>/device/ti/<board>/fastboot.sh for exact images to copy into flashing directory.

    cd ~/ti-processor-sdk-android-beagle_x15-<version>/board-support/ cp -rv prebuilt-images emmc_files cp -v ./aosp-<version>/out/target/product/beagle_x15/{boot.img,boot_fit.img,recovery.img,system.img,userdata.img,vendor.img} emmc_files cp -v ./aosp-<version>/device/ti/beagle_x15/fastboot.sh emmc_files cp -v ./aosp-<version>/out/host/linux-x86/bin/{simg2img,mkbootimg,fastboot,adb} emmc_files cp -v ./linux-<version>/arch/arm/boot/zImage emmc_files/zImage-beagle_x15.bin cp -v ./linux-<version>/arch/arm/boot/dts/am57*.dtb emmc_files cp -v ./u-boot-<version>/MLO emmc_files cp -v ./u-boot-<version>/u-boot.img emmc_files

    cd ~/ti-processor-sdk-android-am65xx-evm-<version>/board-support/ cp -rv prebuilt-images emmc_files cp -v ./aosp-<version>/out/target/product/am65xevm/{boot_fit.img,system.img,userdata.img,vendor.img} emmc_files cp -v ./aosp-<version>/device/ti/am65xevm/fastboot.sh emmc_files cp -v ./aosp-<version>/out/host/linux-x86/bin/{simg2img,mkbootimg,fastboot,adb} emmc_files cp -v ./aosp-<version>/out/host/linux-x86/lib64/{libc++.so,libcutils.so,liblog.so,libselinux.so,libpcre2.so} emmc_files cp -v ./u-boot_build/a53/u-boot.img emmc_files cp -v ./u-boot_build/a53/tispl.bin emmc_files cp -v ./u-boot_build/r5/tiboot3.bin emmc_files
  2. Ensure the device is plugged in with USB Host and Debug UART/Serial Debug.
  3. Open a terminal debugger to view console output from the device (dmesg: kernel ring buffer, logcat: log of system messages):
    4. $ sudo picocom -b 115200 /dev/ttyUSB0
  4. Enable fastboot on the device through the terminal debugger:
    5. => fastboot 0
  5. In a different terminal, change directory to emmc_files and run the fastboot.sh script:
    6. $ cd ~/ti-processor-sdk-android-<board>-<version>/board-support/emmc_files $ sudo ./fastboot.sh; sudo ./fastboot reboot
