    Yes, the primary boot has to be done using one of the supported boot modes.

    What do you mean by "by modifying the boot configuration reg value"

    Hi Nabeel,

    So anyway we need any of the default booting options should be used for 1st stage booting even though we store the application code, system image kinda stuffs in an external medium such as SD card or MMC card which should be enabled for second stage booting by modifying the boot configuration reg value ? Am I correct ?

    HI,

    SC587 does not support the MSI booting. So booting through MSI on power on is not possible.

    However implementing a second stage boot is possible. In that case booting form both SD as well as MMC cards is possible

  • Hi we have some more doubts regarding the MMC Booting options of ADSP-SC587. Please do help us to get the required information.

    1.      How could we enable the MMC boot option ?

    2.     Does the MSI booting option is limited to Multimedia Cards only or can we use uSD cards connected via MSI for booting ?

    3.     What will be the boot mobe [0:2] pin configuration for MMC booting ?
