Sorry, about the typo in the title, it should be: 

Whether the boot address is able to be switched. 

Hello Hong,

Thank you very much for your question.

As per my understanding, you want to boot from 0x400000 for OSPI and then switch to 0x0 to boot again for OSPI?

Is my understanding correct?

Can you also confirm if you meant 0x400000 or 0x40000000?

Regards,

Vaibhav

Hello Vaibhav, 

Thanks for replying this question,

Yes, your understanding is correct. 

Based on TRM, the backup boot address is 0x400_000 for OSPI/SPI as below.  I meant 0x400000. 

Thanks,

Hong

If it boots succeeds, whether it is possible to re-configure back to be 0x0 as default?

Allow me sometime to comment on this.
