MIMXRT1170 EVK flexspi issues

[GLantzTCore]

I'm using the MIMXRT1170 EVK with the IAR tool set.  I am running the flexspi_nor_polling_transfer project from the driver_examples provided with the SDK.  I am building the debug project target which should NOT use the flexspi flash as I understand it.  The program fails on a memory compare between the program buffer and the read buffer.  I have not modified any of the code, the project is as provided in SDK 2.15.  Any help/suggestions about why the provided example fails would be appreciated.  I'm intending to use this code as a basis to program flash in the field via boot code that resides in on-chip flash.

if (memcmp(s_nor_program_buffer, s_nor_read_buffer, sizeof(s_nor_program_buffer)))
{
PRINTF("Erase data - read out data value incorrect !\r\n ");
return -1;
}

Reset of System (default) is what my settings are.  It does not run successfully.

Hi @GLantzTCore ,

   Thanks for your updated information, please also check the boot mode, it should be in the serial download mode, SW1:1-OFF,2-OFF,3-ON,4-OFF.

    Now, follow me to do more testing, in fact, my side works OK:

  1. Try the flexspi_nor_debug

Whether this method works OK on your side?

At least, this works on my side, no need to modify the reset type

2. if point 1 is working, you also can in the debug project, prepreocessor add:

XIP_EXTERNAL_FLASH=1

try it again, this 2 method works on my MIMXRT1170-EVK rev C4 board.

Wish it helps you!
Best Regards,

Kerry

I resolved my issue.  I had created my own pin_mux.c and had an error in it.  The example application and my test code now work erasing/writing/reading flash.  Thanks for your attention to my issue.
