You may take a look at the driver for mx25 here to see if it helps:

Thanks for Reply,

Do you have any Example code or Application for these,Please send me.

Thanks,

Gopal.

As far as I know, there is no application note on this.

 

There is a good blog.

We have some KBA, maybe they are written for different use case, you could take a look at it. Not sure if they helps.

Hi,

Anybody give me reply?

Thanks,

Gopal.

Hi,

 

As Eric mentioned, you may want to study the external SPI flash bootloader code to figure out how to use it.

Additionally, you can open "spiflash-class1.c", it contains the SPI flash routines (open a Connect example project and enable the "SPI flash" plugin, it will add the "spi-flash" folder to the project, there you can open "spiflash-class1.c".

 

BR,
