    Compatible NAND Memory

    Hi, folks
    I am using the Zynq Ultrascale+ MPSoC on a custom board and have an 8bit NAND Flash memory to boot from. When I try to program the Flash using the Vitis Program Flash Memory tool I am able to measure the CE pin and it does go low and high so I believe the tool is trying to program the NAND flash but in the Vitis Console window it show 8 bad blocks and fails to successfully write data. The part number of my device: MT29F8G08ADBDAH4-AAT
    (data source: https://www.apogeeweb.net/productdetail/Micron-MT29F8G08ADBDAH4-AAT-D-w8Ub2vtR)

    How do determine if the memory I have is compatible with the Vitis Program Flash Utility?

      That Flash does have a limited lifespan. I’m an older embedded designer and encounter new engineers that run into what you are writing about but the new person assumed the Flash was good forever. It’s not.

      A lot was left out of this story so I’ll assume it’s the usual story where it worked and now it doesn’t. This means you replace the worn out Flash component.
