    Hong,

    I will try to check with the prebuilt SD card image and let your know if I run into the same issue. In the meantime, can you use the images provided here and let us know if you are able to see any UART logs:
    processor_sdk_rtos_am335x_4_02_00_09\prebuilt-sdcards\evmAM335x\sd_card_files

    We had a few issues reported with prebuilt images from this release but they were resolved when the bootloader was rebuilt using the instructions provided here:
    processors.wiki.ti.com/.../AM437x

    The steps will build bootloader at the location pdk_am335x_1_0_9\packages\ti\starterware\binary\bootloader\bin\am335x-evm. Let us know if you continue to observe this issue and we will provide further assistance.

    Regards,
    Rahul
