TMS320DM368: SDMCC Copying Stop during booting.

Part Number: TMS320DM368

I’m developing video compression unit using TMS320DM368ZCED DPS. Sometimes (2 of 10), my unit halt during SDMMC Copy when BTSEL and AECFG set to 000.

 

////////////////////////////////////////

initialization passed!

TI UBL Version: 1.50

Booting Catalog Boot Loader

BootMode = SD/MMC

Starting SDMMC Copy...

///////////////////////////////////////

 

Situation in halt is above. When BTSEL set to 010, it never occurred.

I think that some problems come up in bootmode change NAND to SDMMC.

However, I can’t certain where/when is debugging point in booting sequence.

Please, let me know debugging point or method to solve this problem.

  • Hi,

    I am trying to understand your issue. Please can you try below experiments and share your observations.

    • Are you using prebuilt binaries? If, not try with it .
    • Are you running this test on custom hardware? If not, please can you try with TI EVM?  
    • Run "nand scrup.chip" from uboot and then boot from SD card [set BTSEL to 000]

    Thanks

  • Thank you four your reply.
    My answars are bellow,

    •Are you using prebuilt binaries? If, not try with it .
    -> In our system, binaries are built via linux (ubunt) environment.

    •Are you running this test on custom hardware? If not, please can you try with TI EVM?
    -> Our hardware is custom made based on EVM.
    -> This situation is became again in custom hardware.

    •Run "nand scrup.chip" from uboot and then boot from SD card [set BTSEL to 000]
    -> Our hardware dosen't have flash memory.

    Thanks
