Hi,

My cutuom board has MIMXRT1021DAF5A, qspi flash (W25Q32 ) and fpga(LCMXO2-1200HC),

flash connect to FlexSPI A1 port, and fpga connect to B1 port, flexspi clock is 120M, 

flash work ok, but my fpga's max freq is 50M, How can I  set different clock freq on flexspi B1 port?

Hi hai nie,

    The RT1021 just have one FlexSPI interface, so the clock can't be used as two frequence.

    Maybe you can consider other SPI interface, like LPSPI.

Wish it helps you!

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


Have a great day,
Kerry
