Hi all

 

I have a question about QSPI nor flash config file such as qspi-nor-xxx-config and this thread is related following thread.

https://community.nxp.com/thread/490051

 

My customer use N25Q032A of micron and the config file setting is as follow.

They have already launched with the flash and the settings.

 

Setting a "ddr_mode_enable = 1"

Use ADDR and READ

The command sequence set for lut is as follows

 

      CMD - Read Zero Latency(03h)

      ADDR

      READ

      JMP_ON_CS

 

With the above settings, the program can be loaded from the NOR flash memory and executed.

Their biggest concern is whether or not the loading of the program in the NOR flash may fail due to the above setting.

 

 

Is there a possibility that program loading will fail with the above settings ?
