3.6 Steps to Install vision_apps With tiny-rootfs on SD Card

  1. Insert the SD card and check whether /dev/sdb exists (already formatted card). If yes, do the following steps:
    cp $PSDK_LINUX_PATH/filesystem/tisdk-tiny-image-j7-evm.tar.xz $PSDK_RTOS_PATH
umount /dev/sdb1
umount /dev/sdb2
cd ${PSDK_RTOS_PATH}
sudo psdk_rtos/scripts/mk-linux-card.sh /dev/sdb
  2. Download the below script to $PSDKRA_PATH/psdk_rtos/scripts/ folder and give executable permissions:
    1. install_to_sd_card_tiny.sh
      cd $PSDKRA_PATH
chmod +x psdk_rtos/scripts/install_to_sd_card_tiny.sh
cp $PSDKLA/filesystem/tisdk-tiny-image-j7-evm.tar.xz .
./psdk_rtos/scripts/install_to_sd_card_tiny.sh
