Add 4-byte addressing to FLEXSPI flash driver

I'm using 256Mb external flash. That requires using 4-byte addressing. It's easy easy enough to see how to modify customLUT to use the 4-byte versions of the various commands, but how and where do I add the commands to enable and disable 4-byte addressing mode? The memory chip is a Macronix MX25L25645G, I'm using MCUXpresso SDK 2.6.2 (which I'm resistant to changing at this stage in the development cycle, unless it is unavoidable), the MCU is MIMXRT1062DVJ6A, and the IDE is MCUXpresso 11.2.0.

Nothing other than updating the customLUT is required to use 4-byte addressing mode for this flash chip.

Hi Jeffery Thompson ,

   Thanks for your updated information.

  Do you already solve the issues but update the LUT table with 4Byte address mode?

  Do you still have issues with this case?

 If you still have questions about it, please kindly let me know.

Best Regards,

Kerry
