SPI Rx issue interfacing S32K341 and NAND MT29F1G01ABAFDSF

Hi,

   I am interfacing NAND MT29F1G01ABAFDSF with S32K341 through SPI. I am calling Synchronous Transmit to send command/data and Asynchronous Transmit function for reading data in Halfduplex mode. i am calling respective Halfduplex functions to transmit and receive. This is same way was followed in example code. I am able to see SCK and data during transmission however there is no signal coming for reading. i am using LPSPI drivers. I tried both polling and interrupt and the result is same. Please let me know what may be the issue and do share reference code if there for LPSPI to read/write to NAND from S32K341.

I am afraid supporting for external third-party components is out of scope of our free technical support.

However you could start with scope measurement to check whether you are fulfill memory datasheet requirements.

I would consider using of QuadSPI module instead of LPSPI.

We can provide SPI examples for both modules, QuadSPI and LPSPI.
