MIMXRT1180-EVK How to boot from U10 (FlexSPI1_B)

[silvio-vallorani]

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!

@Omar_Anguiano I cannot find the FLASH_CONNECTION_SEL, can you help me in what and how I should fuse otp to boot from U10?

Thank you very much!

[Omar_Anguiano · Accepted solution]

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

Omar

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?

[Omar_Anguiano]

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.
