using QSPI for interfacing a sensor using imxrt1170 evkb board

[Ruthvik_R]

Hi all ,

we are using a mimxrt1170 evkb board for our developement purpose . In this board the QSPi is used for flash the meory by default. i would like to know if it is possible to use the qspi for the purpose of interfacing a sensor that communicates using qspi by using a different flash method. is this possible in the evk kit and is there support for this on zephyr as our eventual application will be a zephyr application.

Thank you

Q1: if it is possible to use the qspi for the purpose of interfacing a sensor that communicates using qspi by using a different flash method.

--> No, there are two FlexSPI interface ports(A and B), FlexSPI supports communication with both serial flash memory and serial RAM devices, it is dedicated for external memory device.

Q2: is this possible in the evk kit and is there support for this on zephyr as our eventual application will be a zephyr application.

--> FlexSPI is used for is25wp128, its dtsi shows: https://github.com/zephyrproject-rtos/zephyr/blob/main/boards/nxp/mimxrt1170_evk/mimxrt1170_evk.dtsi...
