Greetings,

 

We would like to move the QSPI Flash from FlexSPI_A to FlexSPI_B.

Would like to have the clarification, before going in for that change.

Are there any known issues in doing so ?

 

Thanks,

Hello, 

ROM does not support boot from FLEXSPI_B port directly. ROM always seeks a valid Flash Configuration Block from the
FLEXSPI_A port and then re-configures the FLEXSPI controller using the valid parameters in the block read-out. This reconfiguration can include but is not limited to, FLEXSPI_B port support.

Have a great day,

Victor
