Troubleshooting Steps - Build Error

MontanaEE

I'm running into this issue quite often where I have a Build failure.  I'm sure to others the way to troubleshoot what the issue is may be obvious, but being fairly new to this, what are the steps to try to remedy this?  What are the highlighted areas actually telling me?  Using VS Code version 1.91.1

When I run into this, I usually have to back out changes and start over, but is there a better way to troubleshoot this?  Here is the output in VS Code in PDF.

    What are you trying to compile? Where did you get the template of your project? What is the memory partition of the device?
    The error you're encountering seems to be related to the function arm_core_mpu_configure_dynamic_mpu_regions in the Zephyr project. This function is part of the Memory Protection Unit (MPU) configuration for ARM Cortex-M processors. The error message suggests that the function is trying to read 12 bytes from a region of size 0, which is causing an overread warning.
    The MPU is a hardware unit on ARM Cortex-M processors that provides memory protection by allowing fine-grained control over the access permissions of different memory regions. It can be used to protect certain memory regions from being accessed by unprivileged code, for example.
    The function arm_core_mpu_configure_dynamic_mpu_regions is used to configure dynamic MPU regions, which are re-programmed at each thread context switch. These regions can include an unprivileged RW region for the current thread’s stack area, a read-only region for the MPU stack guard, and unprivileged RW regions for the partitions of the current thread’s application memory domain
    The error you're seeing could be due to a misconfiguration of these dynamic MPU regions, or it could be a bug in the Zephyr project. It's hard to say without more information. You might want to check the configuration of your dynamic MPU regions.
