cannot interface NAND flash with nrf52840

[shilpa]

Hello,

I am using sdk version 15.2.0 and nrf52840. In the application NAND flash TC58CYG2S0HRAIG is used. We are using flash to store values which we receive from the USB . This flash use SPI interfacing . It is not able  to implement the writing and reading to the flash in the specified sequence .So it would be glad if you provide any support for the same.The datasheet for the same is also attached.

The simplest operation for this device is to read the single byte "ID" located at register 0x9F.

That would be the simplest operation possible. Can you perform this operation?

When you read this register you should get the values [0x98, 0xBD] back.

See section 4.13 (page 31) of the data sheet. There is a timing waveform which your scope or other debug device (logic analyzer) should match.
