ZYNQ and NAND Flash

Hello,

 

We are working on a custom board with a ZYNQ FPGA (xc7z020-clg484, speed grade: -3).

 

On the board there is a Micron NAND Flash (MT29F1G08ABBDAHC).

 

The example we are using is C:\Xilinx\14.5\ISE_DS\EDK\sw\XilinxProcessorIPLib\drivers\nandps_v1_03_a.

 

The test output indicates that the test is failed. During the debug through the test, we were able to receive the "ONFI" code. So that indicates the timing is OK I guess. However we can only read "FFh" after the write operation.

 

Did anyone manage to get it working or has an idea?

 

Thanks,
Berk

Hi Berk,

 

Can you send me the process which you followed to select the NAND flash on the PS side. Which version of XPS are you using? 

 

However since this is Embedded Query i am moving it to the Embedded Board.

Thanks,
Anirudh
