TDA4VM: MCUSW running McSPI example problem

Part Number: TDA4VM

On The EVM I want to try to run the examples about MCUSW McSPI.

I just try to boot on SD card, and I used the steps below:

  1. Copy SBL binary sbl_mmcsd_img_mcu1_0_release.tiimage as tiboot3.bin
  2. Copy the sysfw.bin form (SDK Install Directory)/(pdk-install-folder)/packages/ti/drv/sciclient/soc/V1/sysfw.bin as sysfw.bin
  3. Copy the application from (SDK Install Directory)/mcusw_xx.yy.xx.bb/binary/(driver name)_app/bin/j721e_evm)/.*appimage to the SD card boot partition as app
  4. MMC SD: Ensure The bootmode switches are configured as described in (J721E EVM MMC/SD Boot Mode)

There is no output from UART,  did I miss anything here?

 

 


Best Regard,
Leo Ho

    Hi Leo Ho,

    You can check a few things -

    1. Have you partitioned the SD card correctly?
      1. You need to have a FAT32 partition named - boot
      2. This is where your app, sysfw.bin and tiboot3.bin goes.
    2. You have connected to the correct UART physically (J43 i.e. MCU UART)
    3. You have opened the correct UART instance
      1. The MCU UART has two instances and you need to connect to the 2nd instance on teraterm/minicom
    4. Your teraterm/minicom settings are correct.
      1. Your baud rate should be 115200

    Can you please check the above? Also, please do mention what SDK and which specific example are you trying to run.

    Regards,

    Karan
