Hello NXP Team
I am working with the i MX RT 1176 using MCUXpresso IDE and I am trying to flash and debug a CM4 application by itself
The CM4 project builds successfully but during the flash or debug launch the process fails during the download stage and the debugger reports that it cannot write the program counter register and returns an E22 failure
The error occurs before the application begins execution
I am only able to reproduce this issue when attempting to flash or debug the CM4 core directly
A CM7 application flashes and runs correctly on the same board
Based on my understanding the CM4 core depends on CM7 for flash initialization and system setup before CM4 is released
I would like to ask whether this behavior is expected when attempting to flash or debug the CM4 core in standalone mode on the RT1176
I would also like confirmation on the recommended workflow for loading and debugging CM4 applications on this device
Finally, I would like to know whether the E22 failure indicates that the CM4 core has not yet been released or clocked by CM7
Any guidance from the NXP team would be greatly appreciated
Thank you for your time and support
