Hello,

    I am using S25FL064L NAND with c6748 TI processor. I have connected

CS to CS_c6748

SO  to  MISO

WP not connected

VSS to ground

VCC to 3.3V

Reset not connected

SCK to SCK

SI to MOSI

I wanted to communicate to IC. I send 9f RDID command to IC. Attached is the pics. I have channel

1-SI

2-SCLK

3-CS

in the figures. I am continously sending these. But my SO remains at ground level. Why does this happen? At least it should keep first 8 bytes on SO line if I get it corerect. Please make suggestion,why this does not work.

Thanks in advance

With Regards

Shalini
