Can FelxSPI bus be used for regular, non-flash-memory SPI devices?

[oliverco]

I need add'l SPI buses beyond the SPI1, SP2 and SP3 offered, and I thought FlexSPI should be possible to be used as a regular single-lane SPI bus?

Hello @oliverco 

FlexSPI is primarily designed for interfacing with NOR/NAND Flash memory devices, but you can use it to interface other kind of SPI devices, but you should modify the device tree and maybe the driver for FleSPI.

Maybe it is preferible to use the SPI peripheral directly.

Also you can test if FlexSPI works with your device with spidev_test.

Best regards,
