Help with using the octal flash on RT1160-EVK

[danielberhe]

Hi All,

I'm trying to use the octal flash on the RT1160-EVK without much success.

I modified the resistors on the board as outlined in the Board User Manual. Have set SW1 to 0010, and SW2 to 0010000000.

I'm using a modified version of the example project evkmimxrt1160_flexspi_nor_edma_transfer_cm7 to test this. Changed the flash config in evkmimxrt1160_flexspi_nor_config.c following examples from https://community.nxp.com/t5/i-MX-RT/RT1170-EVK-Octal-Flash-not-usable/m-p/1249206.

The code compiles but never gets to main when I run it (see screenshot below):

Any idea where I'm going wrong? I've attached the MCUXpresso project.

Hi @danielberhe ,

   Don't worry, it is not difficult, please refer to my document, although it is for the RT1170, but RT1160 is the same situation:

https://community.nxp.com/t5/i-MX-RT-Knowledge-Base/RT1170-Octal-flash-enablement/ta-p/1498369

  You can try it at first.

If you meet any issues, please kindly let me know.

Best Regards,

Kerry

Hi Kerry,

Thank you for the link.

I've had partial success following the document you linked. Running fsl_romapi from RAM appears to work and I was able to get the flash information. Although the the Erase sector and page program bits fail.

No luck with debugging hello world app from octal flash. I've modified the flexspi_nor_config_t to resemble what is in the linked document. I regenerated the cfx file to include the flash reset pin. Below is the console output:

Hi @danielberhe ,

   Which debugger you are using now?

    As you also need the related flashloader file, different debugger is using the different flashloader.

    CMSIS DAP is using the .cfx,  JLINK, I suggest you use the RT-UFL.

   If you use the .cfx, do you try my chapter 4. CMSIS DAP Flashloader

    Do you generate the .cfx file again?

Best Regards,

Kerry

Hi Kerry,

I'm using the DAP flashloader and yes, I did follow section 4 of the document and regenerated the .cfx. I then used that .cfx by updating my project in properties->C/C++ Build->MCU settings.

Regards,

Daniel

Hi @danielberhe ,

  Share your modified .cfx to me, when I have time, I will test it on my side.

   BTW, you can modify your on board EVK debugger to the JLINK, then try the RT-UFL, whether that method works or not?

   You can firmware the on board debugger to JLINK with the LPCScrypt:

   https://www.nxp.com/lpcscrypt

   Please try it on your side, the RT-UFL, you can use my doc mentioned file.

Best Regards,

Kerry

Hello @kerryzhou,

I been trying to do the same with the rt600 on a custom evk runnning on flexspi port A Octal. 

By following your note on the rt1170, I was able to get to the point where in the IDE seems to do a successful operation when I flash it with the RT UFL algo. But is not actually flashing. 


Also, I get this error when I try to erase memory with j-commander :

To what I believe is that RT algorithm needs to support octal and I need to enable it. Can you give some detail on how to do this with the rt600 ?

Thanks!
