AM2432: SBL example in SDK

Part Number: AM2432
Other Parts Discussed in Thread: AM2434, SYSCONFIG

Hi Team,

A customer has been working with our LP-AM243x (Quad-core) and have been wanting to transition to the AM2432 (dual-core). 

Is there any migration effort needed to port the OSPI SBL example in the sdk (/examples/drivers/boot/sbl_ospi/am243x-evm/r5fss0-0_nortos) to the dual core device from the quad-core evm? Is there a migration guide or available documentation for this?

BR,

    Hi Ryan,

    The OSPI SBL only involve two cores: R5_0_0 and DMSC (M3), so it should not change from quad-core (AM2434) to dual-core (AM2432).

    As you may know, there two packages of AM243x: ALV and ALX. ALV is used on the AM243x GP EVM and ALX is used on AM243x LaunchPad. There are two different versions of the OSPI SBL:

    C:\ti\mcu_plus_sdk_am243x_08_05_00_24\examples\drivers\boot\sbl_ospi\am243x-evm and

    C:\ti\mcu_plus_sdk_am243x_08_05_00_24\examples\drivers\boot\sbl_ospi\am243x-lp

    Best regards,

    Hi Ming,

    Thanks for the quick and clear answer! Are there any modifications needed to the Sysconfig editor also for the migration from the quad to dual core?

    Hi Ryan,

    I do not think there is any change needed from quad-core to dual core, because SBL only need to access to two cores: R5F_0_0 and DMSC (M3), there is no difference between the quad-core and dual core versions from that perspective. They both have R5F_0_0 and DMSC (M3).

    Best regards,
