AM263P4-Q1: About the OCRAM region reserved for SBL

Could you please let us know any precautions when using the OCRAM area reserved for SBL as application RAM in the AM263Px MCU+ SDK 09.02.00 environment?

    The OCRAM area in the SBL is typically reserved for its code and data region and we say not to use this region, as if there is an overlap in the text or rodata of APP with the code region of SBL in RAM, then when SBL parses this application from Flash to RAM, the SBL code region could be overwritten, cause it to not execute correctly.

    But the SBL region in RAM is only needed while SBL is executing. Post that, in Application, these regions are free to use.

    Thanks and Regards,
