[SOLVED] What is the minimum .reg configuration for monting eMMC2?? RRS feed

  • Question

  • Hello Friends,

    Greetings for the day!!

    As, I have a board that contains the eMMC2(slot=3). We have made some changes in the driver for make it capable for slot=3. Now, the turn of .reg files. We have made all the required entries for Driver\BuiltIn\SDHC3. And driver is taking the values correctly. Now the part of remaining entries related to file system, profiles, partition, partition table etc

    I have made entries are as - 

        "PartitionDriver"="mspart.dll";; -- Required
        "Folder"="";; -- Required

        "Name"="MMC Card"
        "Folder"="MMC_CARD"	;MC Card


       ;; "AutoMount"=dword:1

        "LoadFlags"= dword:1

    I have read lot of document related to the issue that eMMC2 is not mounted for most of the persons. In every document I have observed that they are using different keys and keys values.. I am confused that what is the minimum keys and keys values required  for the eMMC2 to be mounted apart from driver level.... ???

    With this values my logs are as -

  • Hello Friends,

    I am happy to intimate you that I have self solved the above problem with minimal configuration as shown below -

        "PartitionDriver"="mspart.dll";; -- Required
        "Folder"="";; -- Required
        "Name"="MMC Card"
        "Folder"="MMC_CARD"	;MC Card
    But, atleast you have to find the tool that format and create single partition as per your requirement ...
