Can RT1052 spi nor flash can be used as a XIP place and a writalbe fat filesystem at the same time

[huijieshen]

Dear Dir:

   I used spi nor flash as a XIP media. But since my flash is big, there are a lot of free space left . So I am considering split the XIP flash into 2 parts. Part I is used as XIP storage place, Part 2 is used as a FAT fileystem. I wander if this goal can be achieved. 

  Best Regards

Hello, 

Yes, this can be done. Keep in mind that you cannot erase, write or read the part of the flash that you will use as a FAT filesystem while you do XIP from the same flash. For this, you will have to copy to the internal RAM the functions that interact with this part of the flash. I highly recommend you check the following example in the SDK since it works like this.
