Part Number: PROCESSOR-SDK-AM62X
Other Parts Discussed in Thread: UNIFLASH

Hi,

After reading this FAQ:

  1. You will be able to run the MCU PLUS SDK R5_0_0 examples via SBL Null.
  2. You will be able to see the output of the SDK examples on the WAKEUP Terminal.

Follow the steps mentioned in the answer.

The steps are mentioned for the SDK example(UART_ECHO) and

you can locate it at the following location: 

C:\ti\mcu_plus_sdk_am62x_08_06_00_18\examples\drivers\uart\uart_echo\am62x-sk\r5fss0-0_freertos

Simply apply the steps for other examples.

Thanks..

    You will have to follow the steps mentioned below: (Following is for UART Echo example)

    1. Power Off the EVM
    2. Connect the terminal to UART port in CCS.
    3. Set the board in UART boot mode.
    4. Power On EVM.
    5. check for the logs, 'C' character will be coming in every 2-3 sec.
    6. Disconnect the terminal from UART port in CCS.
    7. Create appimage with the help of following command.
      1. cd ${SDK_INSTALL_PATH}
      2. gmake -s -C examples/drivers/uart/uart_echo/am62x-sk/r5fss0-0_freertos/ti-arm-clang
    1. Go to the path "${SDK_INSTALL_PATH}/tools/boot/sbl_prebuilt/am62x-sk/default_sbl_null.cfg"
    2. Change the path of appimage at line #31 with your appimage and save the changes. 
    3. Open command prompt and run the below command
      cd ${SDK_INSTALL_PATH}/tools/boot
      python uart_uniflash.py -p COM<X> --cfg=sbl_prebuilt/am62x-sk/default_sbl_null.cfg (replace X with COM NO.)
    4. After successful completion of above steps, Power Off the EVM.
    5. Set the board in OSPI Boot Mode.
    6. Connect the terminal to UART Ports in CCS.
    7. Power On the EVM.
    8. Input 8 characters in the UART Terminal.
    9. See the logs coming on terminal connected to UART Ports in CCS.

    You should be able to take input in the 3rd smallest COM terminal, as mentioned in the screenshot below.
