imx rt 1024 internal flash configure as RWW

Hi,

We are using the imx rt 1024 cpu to run our application. We use a portion of the flash as sort of "eeprom", In order to read / write to flash while executing code at the same time, we need RWW flash. We know by default this is not the case, so we run the nor_flash module (among others) in ITC ram to cope with this.

We were wondering though, is there any way to configure the flash so that we in fact are allowed to use it as RWW? I believe by default we run in SPI quad mode. Can we use a different mode which makes the flash usable as RWW?

The internal flash doesn't support RWW function.

You have to run the code in RAM when you opreating the Flash.
