NOR Octal SPI Flash Driver (.cfx)

[fernando_dabadia]

Hi,

I'm working on a custom board, using the imxRT1051. We will use a NOR Octal flash memory for XIP.
I did a search for drivers (.cfx) to configure MCUXpresso and then load the firmware into memory but I didn't find any specific ones for this type of memory.

Would it be possible to provide the project for MCUXpresso with the code of some driver for NOR Octal SFDP? Or even indicate me some driver that works for this type of memory? I looked in the IDE folder with examples of flashdrivers but they aren't fit.

Best regards,

Fernando.

What is your octal flash device part?

Maybe you can try MCUBootUtility tool to flash octal device and debug project without downloading in IDE

I was able to access the flash using the MCU Boot Utility.

Now I'm trying to generate/I need the .cfx to integrate in MCUXpresso and allow me to program the NOR flash Octal memory to be able to enter debug mode.

Hi @fernando_dabadia ,

You can refer to this post. https://community.nxp.com/t5/i-MX-RT/Flash-driver-for-GD25LX256/m-p/1072930

Hi jingpan.

It worked, I could use the QSPI .cfx driver.

Thank you all for the help.

Hi Jay.

The part is  MX25UW12845G (Macronix).

I tried using the program but It couldn't work. Do you have any suggestions for configuring the program to make it work? In fact, the "closest to work" was when I configured it as QuadSPI SFDP and it even recognized the memory (it was able to read the memory size) but it cannot proceed, accessing the data because I believe that only the part related to the SFDP (the identification of memory parameters) worked.

Anyway, I need the .cfx so that I can integrate it into my development environment, so if you have at least similar memory code project (MCUXpresso), it will help a lot (I can adjust it here for my specific PN). I'm trying to change the driver of a QuadSPI memory...
