i.MX RT1020 FlexSPI boot from non-standard flash device

[loganw]

I'm designing a custom board with the i.MX RT1020 processor. I'm using ISSI IS25LP080D flash device. So far I've been able to program the flash device (I've done this through command line instructions using sdphost.exe and blhost.exe over UART as well as NXP's MCU Boot Utility v1.1.0). However, when I try to do an internal boot (BOOT_MODE[1:0] = 10b) the application software does not appear to be running.

I think there's something in the Flash Device Config Block that needs to be edited since I'm using a different flash device than the EVK board (IS25LP064A), specifically the LUT part of the block. I'm unsure how to proceed and was wondering if there are any helpful articles or tips on how to configure the board for this flash device.

Hi,

The following sequence works for me (with the same flash on different EVK board):

Then I use NXP-MCUBootUtility with the following configuration:

Of course, download is done in serial downloader mode, after downloading you should switch to boot from QSPI mode.

Hi Logan Witter,

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
After comparing the datasheet of the ISSI IS25LP080D and IS25LP064A, I consider the ISSI IS25LP080D should be compatible with the IS25LP064A, in another word, the LUT table needn't be modified, however, other parameters should be updated, likes the flash size, page size, etc, thus please check them.
I was wondering if you can share the screenshot of command line instructions which is used to program the ISSI IS25LP080D, in further, whether you are able to debug ISSI IS25LP080D in the MCUXpresso, or other IDE.
Have a great day,
TIC

Thanks for the reply. I was able to get the application software to run in internal boot mode after a small change to the project settings. Attached is a screenshot with the correct settings. I had checked the "Plain load image" box when I needed it to be unchecked. XIP is now working properly from the flash device.
