Hello,

I need to develop an application that reads a file in a SD card and write its content to LPC4357 Flash memory.

Do I need to format the LPC4357 memory in some filesystem like FAT?

Is there and example that does it?

Any tip will be very helpful,
Thanks.

Use IAP calls (as documented in the User Manual) to write to Flash.

Internal Flash is just linear memory. Only code running on the LPC4357 can access the Flash, so you do not need to format it. You just need to place it into a known location so you can retreive the file and its contents.

Thanks for your answer!

I need to create a file with a path like C://file.txt. Can I do it without a filesystem?

And if I want to write in a external flash, is there an example for it?
