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.</P><P>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?</P> Wed, 18 Jan 2023 15:35:11 GMT bp1979 2023-01-18T15:35:11Z https://community.nxp.com/t5/i-MX-RT-Crossover-MCUs/imx-rt-1024-internal-flash-configure-as-RWW/m-p/1584737#M23338 <P>Hi,</P><P>We are using the imx rt 1024 cpu to run our application.
