Hi,

I'm using ARM-A8 BSP WINEC7 for AM387x/DM8148 EVM from mistral.

I followed the steps mentioned in

http://processors.wiki.ti.com/index.php/Persistent_Registry_in_ARM-A8_BSP

for SD/MMC Persistent Storage

I have attached the platform.reg used..

IMGREGHIVE_SD, PRJ_ENABLE_REGFLUSH_THREAD,  BSP_PRJ_PERSIST_REG 

Thanks

    Sorry, I guess I was too quick in clicking post..

    I'm selecting ROM-only file system and Hive based registry

    Only the TI logo comes up, why is SD not getting mounted as RFS?

    I have commented out mounting RAMDisk as root in Profiles\RAMDisk\FATFS ..

    Is there anything I'm missing?

    Thanks

    Hi,

    I'm using the BSP (2.30.00.03) given by Adeno and trying out on EVM8148, so there is no mention of installing newer .NET versions.

    I've used the patch given in http://processors.wiki.ti.com/index.php/Persistent_Registry_in_ARM-A8_BSP for SD card persistent in sdhc.reg and  in platform.reg added for edma and gpio as below

    ; EDMA Driver
    ; HIVE BOOT SECTION
    ;IF BSP_NOEDMA !

    [HKEY_LOCAL_MACHINE\Drivers\BuiltIn\Edma]
        "Dll"="edmadrvr.dll"
        "Prefix"="EDM"
        "Index"=dword:1
        "Order"=dword:1
    ;;    "Flags"=dword:0
        "Priority256"=dword:46
        "Flags"=dword:1000

    ;ENDIF BSP_NOEDMA !
    ; END HIVE BOOT SECTION

    ; HIVE BOOT SECTION
    #if defined BSP_AM387X_GPIO
    #include "$(_PLATFORMROOT)\AM387x_BSP\SRC\DRIVERS\GPIO\gpio.reg"
         "Flags"=dword:1000
    #endif
    ; END HIVE BOOT SECTION

    The system is not booting, below are the messages from serial term

    We have been able to reproduce the issue with Hive using the settings and the EVM_3530 wiki guide which is on the TI site.  We have also been able to verify that the EVM_3530 SD Hive files are found on the SD card when enabled on the EVM with the 2.30.00 BSP.  We are working on debugging the Hive issue on the Dm8148 and will respond with an update by the end of the week.
