I am working on interfacing a spi flash module s25fl512s with MK64FN1M0vll12 controller.
Using processor expert and ksdk 1.3 I generated the Dspi module for spi 1. Disabled the chip select.
Used gpio pin as chip select .
I am able to get the clock running and also shows the data on SDO pin of microcontroller.
But I am not getting any response from the flash. It giving it as 0's when trying to read identification using RDID command.
I have tried spi in both modes , mode 0 and mode 1, but no success. I tried spi with different speeds with maximum of 1 Mhz.
Any help will be appreciated.
can you list the code to access spi flash? can you paste the scope screenshot of spi signals: SCK/MOSI/MISO/SS?
