MIMXRT1180-EVK How to boot from U10 (FlexSPI1_B)

silvio-vallorani — Wed, 27 Aug 2025 10:12:16 GMT

Good morning,

how can I program and boot from U10 NOR Flash via FlexSPI1_B?

1. DONE: using the rigth driver in project configuration: MIMXRT1180_SFDP_FlexSPI1_B_QSPI.cfx

2. HOW TO DO: programming some OTP (how can I program the OTP? What tool I need to use?)

3. DONE: moving J59 to 1-2 to ensure that U12 is not enabled

So, if there are not more thinghs to do, I only need to know how and what exacly are the OTP to change.

Thank you for your support!

You can Secure Provisioning Tool to burn the fuses and use the other pin group for booting.
The headers of the image must also match the pad configuration.

Thank you for you reply @Omar_Anguiano.

Can you send me a screenshot of the exact point - and the value that I need to write into - to correctly burn the fuses for my needs, please?

The fuse is called xSPI_NOR_CONNECTION_SEL, and it is on fuse word 25.
