TDA4VM-Q1: SBL mmcsd problem

Part Number: TDA4VM-Q1

Hi Experts

     I want to boot from sbl_mmcsd but it have any respond from uart. I using SDK 7.3. with EVM board.

     1:  Using blew command to compile

    make sbl_mmcsd_img_clean

    make sbl_lib_mmcsd_clean

    make sbl_lib_mmcsd

   make sbl_mmcsd_img

  

 2: sudo cp ../boot/sbl/binary/j721e_evm/mmcsd/bin/sbl_mmcsd_img_mcu1_0_release.tiimage /media/boot/tiboot3.bin copy the file to sd card fat4 partition.

   But nothing on UART to show.   

         Finally i build with SDK 8.2, same result. 

         Could you tell me what wrong with me, Thank you
