Use the following steps to flash the binary to OSPI through UART in Linux PC:

1. Configure boot mode of board to UART boot and connect MCU UART serial port of board to host PC.
2. Power cycle the board and get the console instance number, like /dev/ttyUSB1.
3. Navigate to the Uniflash installed directory, dslite.sh script should be present here, and use the following command to load the flash programmer in Linux terminal.

4. # sudo ./dslite.sh --mode processors -c <COM Port> -f <Flash Programmer Binary with Full Path> -i 0
   Example:
   # sudo ./dslite.sh –mode processors -c /dev/ttyUSB1 -f (Path to Uniflash Install Directory) /processors/FlashWriter/j721e_evm /uart_j721e_evm_flash_programmer_release.tiimage -i 0

5. And in same folder, use the following command to flash the binary to OSPI.

6. # sudo ./dslite.sh --mode processors -c <COM Port> -f <Flash Programmer Binary with Full Path> -i 0
   Example:
   # sudo ./dslite.sh –mode processors -c /dev/ttyUSB1 -f (Path to Uniflash Install Directory) /processors/FlashWriter/j721e_evm /uart_j721e_evm_flash_programmer_release.tiimage -i 0

7. Power off the board and change the boot mode to OSPI boot, power on the board and system will start up from OSPI.
