Dear i have a project to build a kind of usb mass storage product the design if finished and done by an engineer, i am a computer scientist so i don't know anything about.

   

I already order some proto pcb of my usb key, the design use this controller : 

   

EZ-USB NX2LP-Flex  ( from mouser : CY7C68023-56LTXC) and eight of  S34ML04G1

   

So if i correctly understood the doc of the nand is programmed the controller act of mass storage device if not it act as "manufactur mode"

   

So what must be done to have a mass storage device working ?

   

Thanks in advance

Hello Marc,

   

You need to program the NAND using NandMfg Utility.

   

You can refer to Nand Manufacturing Utility section in the following document:

Hi i am able to program the nand with nandmfg.exe, the size and number of chip is correct. But the usb mass storage device is recognized by windows with a size of 8G instead of 32G ?

   

Also the usb is only recognized when the nandmfg is runing ?

   

Thanks in advance.
