IMXRT1170 Device Boot-Up

[tbayram]

We have a project on IMXRT1170 DualCore MCU with a special design. Now we are working on IMXRT1170 EVK. Could you give me some brief about this subjects.

1. Device Boot-up
2. Boot Modes (Boot From Fuses)
3. XIP Boot ve NON-XIP Config
4. flexspi_mem_config.c for NOR Flash
5. Memory Map ->> FCB 
6. FlexSPI NOR Boot Flow
7. E-Fuse settings.

Thanks.

Have a nice day

Hi @tbayram ,

  If you want to run the dual core in RT1170, you can refer to the SDK demo.

SDK_2_14_0_MIMXRT1170-EVK\docs\Getting Started with MCUXpresso SDK for MIMXRT1170-EVK.pdf

chapter 3.4 Build a multicore example application

For the item you mentioned:

1. Device Boot-up -> after download the code, no special
2. Boot Modes (Boot From Fuses)-> the same as single core
3. XIP Boot ve NON-XIP Config->the same as single core
4. flexspi_mem_config.c for NOR Flash->the same, you can refer to SDK :SDK_2_14_0_MIMXRT1170-EVK\boards\evkmimxrt1170\multicore_examples
5. Memory Map ->> FCB -> no special
6. FlexSPI NOR Boot Flow-> check the RM
7. E-Fuse settings.-> don't need to special modification boot from fuse.

Wish it helps you!

Best Regards,

Thank you kerryzhou!

we have to change SDRAMs on our design. We think using FlexSPI NOR boot on our design. Im this situations do we need to special modification boot from use?

Boot Modes (Boot From Fuses)-> the same as single core.
you did say same as single core. where can I find explanation about single core?

Thank your answer.

Hi @tbayram ,

  The SDK code is runnning in the nor flash, so, the SDK demo is the best reference to you.

  You can refer to this one:

SDK_2_14_0_MIMXRT1170-EVK\boards\evkmimxrt1170\multicore_examples

  https://mcuxpresso.nxp.com/en/builder?hw=MIMXRT1170-EVK

  Then, to the fuse boot, you just need to burn the related fuse bit, then change the boot mode to boot from fuse is OK.

  But, if you are still not very familiar with the RT1170, I highly suggest you run the multicore demo at first, to learn it, after you design your project, then you can change the fuse situation. the reason is, fuse bit just can be modified from 0 to 1, can be written back, so if you are not familiar with it, it's better to get more knowledge about it before you operate it, please be careful about the fuse operation, thanks.

   More details about the fuse, please refer to the MIMXRT1170RM boot chapter, boot from fuse, that will give you the knowledge.

  If you still have issues about it, please kindly let me know.

Best Regards,

Kerry
