To whom it may concern,
We have developed product using DM385 that is based on IPNC and been mass-producing it.
The product Nand boots and the Nand is using MT29F2G16ABBEA.
The connection between DM385 and Nand is identical to the IPNC Reference Schematic.
We’re trying to replace Nand to another part(another company’s or another parts) but it’s not going well now.
The issue is that,
The Nand can read, write and verify under SD Boot, but cannot Nand boot. (It only shows “CCCCCC…” message)
In other words, we already developed product using DM385 and producing it. Boot Mode is identical to IPNC Reference Schematic.
However changing Nand is our current issue. Nands we have tried so far are MT29F2G16ABBFA, S34MS02G1, MX30UF2G26AB etc.
There may be something we have been missing. We would deeply appreciate if you kindly help us.
