NAND flash replacement for P20x0 (internal or HW ECC required)

We are looking to replace a Samsung K9K8G08U0D NAND on our custom P2010 board (running linux 2.6.35).

  • We need the same footprint as K9K8G08U0D
  • We need to boot from NAND (which we currently do).
  • SW ECC is likely not an option due to performance concerns.

 

We initially hoped to use Micron MT29F8G08ABABA, but seeing that it:

  1. has 4K page size (only 512 and 2K is supported by eLBC - 4K support seems experimental?) and
  2. requires 4-bit ECC (eLBC only has 1-bit ECC) and thus would need SW ECC,

it is probably not an option.

 

We are now investigating Micron MT29F4G08ABADA, with 2K page size.

It still requires 4-bit ECC, but has internal/on-die ECC. Has anyone been successful using P20x0 with it?

 

I would very much like to know:

  1. What NAND flashes have successfully been used in various P20x0 (linux) projects.
  2. If any of the Micron MT29F4G08.. are supported by P2010.

 

Thank you!
