We have a demand to emulate SPI Nor-flash with MCU. So we need to support Quad-SPI, Dual-SPI in slave mode on MCU. Does FlexIO of i.MX series could support this feature? Is there example code for reference?
It is not specified on the reference manual that the flex IO supports quad spi. However it supports normal SPI and on the SDK you can find some examples for this peripheral.
