# Debug Purpose
I want to create a generic CM33 core project to boot and run the CM7 core.
# Reference Materials
evkmimxrt1180_multicore_trigger_cm33 from NXP SDK 26.03
# Debug Steps
1. Compile the evkmimxrt1180_multicore_trigger_cm33 project
2. Compile the evkmimxrt1180_hello_world_cm7 project
3. Switch the board to ISP mode, then open MCUXpresso Secure Provisioning Tool, select the RT1180 development board, and load evkmimxrt1180_multicore_trigger_cm33.axf
4. Add evkmimxrt1180_hello_world_cm7.axf
5. Click the "Build Image" button to generate the merged image file.
6. Click the "Write Image" button
7. Switch the board to normal mode, then power on. You can see the CM33 core output is normal, but the CM7 core output is empty.
Hi @ethan_dang1 ,
Thanks for your interest in NXP MIMXRT series!
Are you following the instructions in this link?
As mentioned in this guide, “CM7 XIP image runs from external FLASH, and multicore_trigger CM33 image runs from internal RAM” does not require modifying the eFuse, while the other does.
However, in the screenshot you provided, it appears that CM33 is not running from the TCM, and CM7 is not running from Flash.
Best regards,
Gavin
