6 Run Instructions

  • Once both PSDKRA and PSDKLA are build and the executables are ready, follow the run instructions provided in the link below from Step 1 to Step 3.
  • The PSDKRA executables are now copied to SD Card.
  • In PSDKLA, three files needs to be copied manually from the paths shown below in PSDKLA folder to "/media/$USER/rootfs/boot/":
    • ${PSDKL_PATH}/board-support/linux-5.10.65+gitAUTOINC+dcc6bedb2c-gdcc6bedb2c/arch/arm64/boot/Image
    • ${PSDKL_PATH}/board-support/linux-5.10.65+gitAUTOINC+dcc6bedb2c-gdcc6bedb2c/arch/arm64/boot/dts/ti/k3-j721e-vision-apps.dtbo
    • ${PSDKL_PATH}/board-support/linux-5.10.65+gitAUTOINC+dcc6bedb2c-gdcc6bedb2c/arch/arm64/boot/dts/ti/k3-j721e-edgeai-apps.dtbo
  • Setup the EVM as shown on this page: https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/08_01_00_11/exports/docs/psdk_rtos/docs/user_guide/evm_setup_j721e.html
    • Connect UART/USB cable and setup universal asynchronous receiver/transmitter (UART) terminal
    • Connect daughter card for camera, display as required
    • Connect power supply
    • Connect HDMI and/or DP display
    • Select SD card boot mode on EVM
    • Insert SD card
  • Power on the EVM
  • First time only: The uboot environment may need to be cleared prior to running with the prebuilt filesystem. The uboot environment can be cleared by first pressing enter to stop the boot process at uboot and come to uboot prompt. The below commands can be entered to clear the uboot environment to default and save the changes.
    env default –a –f
saveenv
  • Power cycle the EVM
  • You should see bootloader prints on the UART terminal and then bootloader will boot linux kernel
