Hi Sathish, Are you using a supported S32K1xx board or a custom board?
There are support to LPSPIx i then EVB boards directory, so I'm assuming it was tested/validated. Maybe someone from NXP could confirm/deny it. Do you have analyzed the SPI pins? if you don't implement the Chip Select logic correctly on your board it will not work. Normally NuttX doesn't use the HW SPI CS. It is obvious for us, but could be something new for you.
