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 ?

Unfortunately, your customer's task is not exactly clear for me. Does the customer want to load a code from QSPI NOR Flash to RAM and then execute it from there? And, their main concern is that the code may become corrupted when copying it from QSPI NOR Flash to RAM, am I correct? Please specify.
Best Regards,
Artur
We would like to know if loading may fail at the time of deployment from QSPI to RAM during boot.
