PROCESSOR-SDK-J721E: PROCESSOR-SDK-J721E

PROCESSOR-SDK-J721E: PROCESSOR-SDK-J721E

Part Number: PROCESSOR-SDK-J721E

Not able to copy the Tiny default image into the SD card.

SD card memory size is 64GB

Ubuntu version: 18.04

SD card is formatted to ext4

Not able to bring the boardup while running the ./setup.sh in the SDK. Tried both the NFS and SDCARD option.

a. Please share me is there any document available to configure the switch (sw3, sw8, and sw9) and how to run the  .setup.sh in the SD card, NFS and UART?  because i dont see the kernel or uboot logs.

b. whether we need to partition the SD card to how many partition? if we are booting in the SD card?

Steps Followed:

Method 1:

a, bring the board in the u-boot  in the UART

b. set the ip address

c. Run the ./setup.sh no SD card attached. Choose NFS and TFTBOOT.

no kernel log message or console in the mincom

Method 2:

a. SD card is partitioned with 2 partition. rootfs and boot (no images copied into the SD card)

b, Bring the board in the u-boot  in the UART

c. set the ip address

d. Run the ./setup.sh.  Choose the SD card option. no kernel log message or console in the mincom

If you can share me document on how to run the .setup.sh for the SD card and NFS it will be helpfull.

    Hi Viswanathan,

    I have a simpler method if you want to use the tiny rootfs.

    cd $PSDK_ATH/bin

    Edit mksdboot.sh

    Replace: root_fs="$sdkdir/filesystem/tisdk-default-image-j7-evm.tar.xz"

    with: root_fs="$sdkdir/filesystem/tisdk-tiny-image-j7-evm.tar.xz"

    That should create an SD card with tiny rootfs.

    Note: This will not have the Image/dtd in the boot folder of rootfs. So you will have to manually copy: board-support/prebuilt-images/Image & board-support/prebuilt-images/k3-j721e-common-proc-board.dtb to /media/$USER/rootfs/boot in the created SD card.

    Let me know if you face issues. If you are unblocked then please click on verify answer.

    Hi Karthi,

    What is the difference between the tisdk-default-image-j7-evm.tar.xz" and tisdk-tiny-image-j7-evm.tar.xz" ? 

    I tried the suggested steps it is not working?

    It seems like DT was not found. Try to copy the entire prebuilt-images folder above to your /rootfs/boot folder of your SD card. Let me know if that works.

    tiny rootfs is a very minimal busybox based file system. It will let you boot to Linux prompt without any additional services enabled. So this is for quick Linux boot.

    This is the same error as: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1050301/processor-sdk-j721e-processor-sdk-j721e

    Let me know if my post on that thread helps you.
