5.1.2 Running the UART Flash Programmer

Note: TI recommends to reset the device before running UART flash programmer so bootROM does not timeout while waiting for UART data.
  1. Navigate to the folder containing the compiled uart_flash_programmer executable.
  2. Run the executable uart_flash_programmer.exe with the following command structure:
    :> uart_flash_programmer.exe -d f29h85x -p COM41 -k ex3_uart_flash_kernel.bin --appcpu1 c29_cpu1_application.bin --hsmrt HSM_runtimeImage.bin --hsmkeys HSM_customKeyCert.bin --cpseccfg sec_cfg_cert.bin --cpappcpu1 c29_cpu1_application.bin --cpapphsm hsm_application.bin

    The program automatically connects to the device and download the CPU1 kernel (-k option) into RAM. If the certificate is valid and authentication is successful, then the device begins executing the kernel in LPAx RAM. Now, the CPU1 kernel is running and waiting for a packet from the host.

  3. The uart_flash_programmer prints the options to the screen to choose from that is sent to the device kernel (see Figure 5-1).
  4. The same options is re-printed after succession of the previous operation.
