imxrt595+ QSPI nor-flash GD25LE64C, cannot boot into our image, hang in bootROM

[ShawnBai]

Hello NXP,

imxrt595 + GD25LE64C, after programming the binary into GD25LE64C, cannot boot, and cannot debug with MCUXpresso IDE, since from the PC, it seems hang in bootROM.

could you help out with this,  does it relate with flash_config?

What should be the next step, thank you.

Facing same problem with Omegle

[Samue99]

I also have a similar problem :(

[Marshall52]

I am also facing this problem,please help me to get out of it

[ShawnBai]

Actually, when I debug it, and pause, the PC is 0x1c04a, I see the disassembly, it seems in bootROM, I guess.

Hi,

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
I think I need more information about your question, firstly, whether you can share your flash_config, next, in your statement, you said the MCU seemed to hang, did it enter the ISP mode?

Have a great day,
TIC

hi zhou，

   thank you for your support.

#if (SIMPLE_VERSION == 1)

}

and ISP is now switched to boot from nor-flash.

Thank you.

Hi,

Thanks for your reply.
Firstly, I'd like to suggest you attach the flash_config again, as the attached code's too hard to review actually.
Second, I find that sflashPadType = kSerialFlash_1Pad, do you want to implement SPI 1 bit serial NOR boot? And I don't think this type supports the XIP function.
Lastly, with regard to normal QSPI flash, you'd better refer to the flash_config of IS25WP064 which is used on other i.MX RT MCU EVK boards, so you can find its flash_config in the SDK library for the MIMXRT1060 board.
Have a great day,
TIC
