ImxRT1050 How to enable QuadSPI in FlexSPI Configuration Block?

Hello there,


I have a custom board based on imxRT1052 with a Cypress Flash. I'm looking to enable the Quad mode in this FlexSPI Configuration Block but I have some questions. I have fullfil the LookUpTable for the flash, but if I want to try to enable the QuadSPI I should enable the lutCustomSeqEnable and then fulfil the lutCustomSeq with the indexes of this LookUpTable in the correct order? This lutCustomSeq is just execute once? or this lutCustomSeq will overwrite the LooUpTable? Or what is the purpose of this field?

 

I'm trying to enable de Quad mode in the boot for production, if it not posible I will incorporate a new routine in the startup of the aplication but I prefer not.


Regards,

Miguel
