NAND on zed board.

Hi All,

May be I am asking a stupid question, but I need some information for the possibility.

Is there any possibility to connect NAND hw part to zed board. please share information.

Thanks,
Jagan.

There are 2 possible ways to connect NAND to Zynq:

Using the built-in NAND controller in the PS (MIO required)

Using IP in the PL for the NAND controller to connect to NAND via PL I/Os
I assume you are referring to the PS-NAND. Unfortunately, we did not design the ZedBoard to allow NAND connection via the PS. You could investigate the 2nd option to connect NAND via the PL, but this would not be a bootable memory.
What would you like to do with the NAND?

Actually I need a PS-NAND, where I could boot from it.

If the nand is possible with zedboard, then it is a complete embedded board with sd/nor/nand boot modes are available. This will help many developers/students .. for doing some experiments.

Any design possibility for PS-NAND?

Thanks,
Jagan.

Jagan,

I am not aware of anyone building an evaluation board with bootable NAND. I think the biggest issue with NAND as a boot device is the wear leveling. That boot block of memory will be hit over and over again.

I suggest you check out this design from Enclustra. I think they have spent the most time investigating NAND with Zynq, and they have chosen a hybrid model with bootable QSPI then switch-over to NAND.
