TDA4VM: How to run app on SE board

Hi,

I have a SE board with a customer key and now I want to run the app on it

1. Replace k3_dev_mpk.pem with cuntom smpk.pem
   $ cp packages/ti/boot/keywriter/scripts/keys/smpk.pem packages/ti/build/makerules/k3_dev_mpk.pem
2. Generated SBL
   $ cd packages/ti/build
   $ make pdk_libs_clean -j8
   $ make -s BOARD=j721e_evm CORE=mcu1_0 BUILD_PROFILE=release pdk_libs -j8
   $ make -s BOARD=j721e_evm CORE=mcu1_0 BUILD_PROFILE=release sbl_mmcsd_img_hs -j8
3. Generate app
   $ make -s board_diag_adc BOARD=j721e_evm -j8
4. copy image to SD card
   cp packages/ti/boot/sbl/binary/j721e_evm_hs/mmcsd/bin/sbl_mmcsd_img_mcu1_0_release.tiimage media/allen/boot/tiboot3.bin
   cp packages/ti/drv/sciclient/soc/V1/tifs_sr1.1-hs-enc.bin media/allen/boot/tifs.bin
   cp packages/ti/binary/board_diag_adc/bin/j721e_evm/board_diag_adc_mcu1_0_release.appimage.signed media/allen/boot/app

Install the SD card and power on, but the MCU UART has no ADC log.
So what to do next？

BRs,
