Linux/PROCESSOR-SDK-AM65X: SD card create issue

vishnu satheesh
Expert 1060 points
Part Number: PROCESSOR-SDK-AM65X

Tool/software: Linux

Hi,

I was successful in building linux image for am65xx-evm. Used MACHINE=am65xx-evm bitbake arago-base-tisdk-image. And all executable was found in /deploy/image/am65xx-evm folder.

I used this link for copying images to sd card. So I executed create-sdcard.sh as root.

But If I select Install prebuilt images , boot partition will populate with u-boot  and other files.

But if I give custom path it is not taking. In that execution itself it will show to give either directory or tar file. I am giving directory which contains following files.

arago-base-tisdk-image-am65xx-evm-20190627052256.rootfs.cpio

Can you help me on this.

    Hi team,

    The files

    sysfw,itb

    tispl.bin

    tiboot3.bin

    u-boot.img

    These files are should present in boot partition of sd card. But after building the images these are soft link to another file. Since the script will search for these files, will it fail because it is not actual file?

    I tried by changing name of the linked file to this name, but got failed.

    How can I copy these files using create-sdcard.sh

    Do I need to copy without script and modify the name ?

    Thanks and Regards,

    Vishnu

    Hello Vishnu,

    The link you provided above does not exist and I am wondering if could you please share which create-sdcard.sh you are using.

    Hello Vishnu,

    Please do not use the Yocto image directory as your custom path for the following purpose:

    a. In the create-sdcard.sh, the following line of code "ISBOOTTAR=`ls $BOOTUSERFILEPATH | grep .tar.xz | awk {'print $1'}`" checks for any tar-ball in the custom directory. Since the Yocto folder contains a bunch of tar-ball, it will execute the tar command on a directory and give an error "xz: /u/yocto/tisdk/build/arago-tmp-external-linaro-toolchain/deploy/images/am65xx-evm/: Is a directory, skipping"

    Solution: Copy the relevant boot images from the Yocto directory to another user created directory. 

    b. The Yocto folder creates multiple variations of the same name, for example: "MLO", "MLO-am57xx-evm" and "MLO-am57xx-evm-2018.01+gitAUTOINC+313dcd69c2-r30.tisdk1". The script will try to copy all the files into one file called MLO and that does not make any sense. By default, the script expects to find only one file named MLO. 

    Solution: Copy the relevant boot/rootfs images from the Yocto directory to another user created directory.

    Krunal

    I copied every images in /deploy/images/am65xx-evm to /u/CustomPath.

    But the same condition I  am facing. Boot partion images are not copying. Because I am give tarball for rootfs it is copying.

    Please help me in this.

    Thanks and Regards,

    Hello Vishnu,

    I am wondering if you have any tar-balls in your "/u/CustomPath/" folder. Personally, I recommend having two folders for boot and rootfs. In the boot folder, please copy all the appropriate images excluding any tar-balls. In the rootfs folder, please copy all the kernel/dtb images.

    Regards,
    Krunal

    Hi krunal,

    I have copied all files in "/deploy/images/"  in yocto build. But still it is not taking those things.

    But rootfs is taking correctly.

    The files should be copied into boot partition are soft llinks to another files. Is this the issue for the script that is not taking and copying it.

    In prebuilt images directory they are not soft link file.

    Do I need to change soft link?

    From this guide it is mentioning to select target boards ( only for AM65xx ) but while running the script I am not getting this prompt.

    How to select the board before its runs.

    Thanks and Regards,

    Vishnu

    Hello Vishnu,

    Please do not copy any soft links to the boot partition and it should contain the raw images. I am wondering if you could please share a picture of your "/u/CustomPath/" folder. Also, please ignore the "Select the Target Board [AM65x/DRA80xM Only]" section because it was only applicable to PSDK5.1. I have filed an internal ticket to update the section.

    Regards,
    Krunal
