MCU-PLUS-SDK-AM261X: How to configure vector offset in SBL?

Joshua Prodduku

Tool/software:

I could not find any documentation on how vector offset is configured in SBL. Can you please provide information on how vector offset is set in SBL to jump to application on reset?

Hi Joshua,

The ROM to SBL transition is documented here: https://dev.ti.com/tirex/explore/node?node=A__AcihA9ANR54nmG9pF-hOHg__AM26X-ACADEMY__t0CaxbG__LATEST

The SBL to application transition is done once the SBL has gotten the authetication success message from HSM RT. SBL then goes ahead and copies the vector table to 0x0 address:

This done by API

Located in : mcu_plus_sdk\source\drivers\bootloader\bootloader.c
