J6EVM5777: SD Card boot on Jacinto6

Part Number: J6EVM5777

Following section is from 

Need some clarifications on loading  6AO.1.1 image to SD CARD for a SD Card boot.

Partitions suggested: xloader, bootloader, boot, environment, system, vendor, recovery. 

Can you please guide me if we need 4 Primary partitions in xloader, bootloader, boot, system and extended in vendor and recovery.

Let me know if you have a document which i can follow .

  • Hi,

    We have not tried booting 6AO.1.1 images from SD card and don't have instructions for it. Only eMMC method is supported.

  • Hi Vishal,

    I am using VAYU ES2.OGPEVM W/1080P TD evaluation board. In the board i am able to boot the board with the previously used image only when the SDCARD is plugged in.

    Can you share the document to Flash Android image(6AO.1.1 ) on Emmc. 

    I came across the following link. Not sure if this is applicable to VAYU ES2.OGPEVM W/1080P hardware. Should we follow the same procedure for this board as in the document link below?

    Please refer section 2.4 Build Instructions Is this procedure applies only to Linux or to Android as well?

  • Follow the documentation tarball from release page
    software-dl.ti.com/.../index_FDS.html

  • Hi Vishal,

    Thanks for the response. I am looking at the release tarball but have some doubts with regard to the flashing procedure.

    Based on the 6AO.1.1 Release Notes i have all the images in emmc_files folder.

    To Flash the same i am stopping the boot at Uboot prompt on VAYU  board using the serial port ttyUSB0 and then i  am running fastboot.sh in the Host machine which is connected to the board. When i do this it says that "fastboot is not running"

    I am also looking into "Android Verified Boot" Document.

    Please give me a procedure  as to how i can image the board. Please let me know if i am missing any steps.

  • The image you attached did not come through.
    Did you type 'fastboot 0' command on u-boot prompt?

    Flashing the image happens over USB, make sure you have connected a micro USB cable from Linux PC to the board also (other than the console USB cable)

    Android verified boot document is for HS device (secure device), you can ignore that.

    Regards,
    Vishal

  • Following images  have got built as described in 6AO.1.1 Release Notes and copied the same to emmc_files directory

    cd $YOUR_PATH
    mkdir emmc_files
    cp -v ${MYDROID}/out/target/product/jacinto6evm/*img emmc_files
    cp -v ${MYDROID}/device/ti/jacinto6evm/fastboot.sh emmc_files
    cp -v ${MYDROID}/out/host/linux-x86/bin/{simg2img,make_ext4fs,mkbootimg,fastboot,adb} emmc_files
    cp -v ${MYDROID}/out/host/linux-x86/lib64/{libc++.so,libcutils.so,liblog.so,libselinux.so,libpcre2.so} emmc_files
    cp -v ${YOUR_PATH}/kernel/android-4.4/arch/arm/boot/zImage emmc_files/kernel
    cp -v ${YOUR_PATH}/kernel/android-4.4/arch/arm/boot/dts/dra7*.dtb emmc_files
    cp -v ${YOUR_PATH}/u-boot/MLO emmc_files/GP_MLO
    cp -v ${YOUR_PATH}/u-boot/MLO emmc_files/
    cp -v ${YOUR_PATH}/u-boot/u-boot.img emmc_files

     I would like to know as to the procedure i need to follow to flash the image.

    I did not type fastboot 0 command

  • The same document has a "Flashing eMMC images" section.
    This section explains the procedure.
