AM2732: Appimage address

Shine

Part Number: AM2732

Hello Champs,

AM2732 BootLoader Appimage default address is 0xA0000, customer has 2 questions about the Appimage address.

1. Can the Appimage address be changed? If it can, does he need to modify the sbl_qspi.release.tiimage offset address? How to rebuild the sbl_qspi.release.tiimage if required?

2. Is there backup address for Appimage? That is, if there is no firmware in 0XA0000, will the bootloader search for the firmware from other address?

Thanks
Regards

Yes App Image offset can be changed by the customer based on their use case.

No, the SBL offsets are fixed in the RBL boot flow. Please refer to the TRM for more information on ROM Boot Flow.

No, the redundant boot address is not supported in SBL. However the RBL supports redundant boot for SBL images at 0x0 and 0x40000.

Hope it helps.
