DRA829V: Backup Boot Mode

Danyon Chu

Part Number: DRA829V

Tool/software:

If primary and backup boot modes are set to SPI on normal bootmode. What is the default Csel that is selected for backup boot mode since it only looks like you can toggle bootmode[7] which controls ports. Is it defaulted to CS0? Is there any way to have it be CS0 or CS1?

    Both primary and backup boot modes will use the same boot mode settings.


    BootMode[6] will be used for port selection during primary boot mode.
    BootMode[7] will be used for port selection during backup boot mode.
    Chip selection is common in both boot modes based on BootMode[4].

    Please refer to TRM for more details.
