How to ensure stable operation and resolve unexpected resets on AVR32UC running Zephyr OS?

Hey guys, who knows how I can go about ensuring the stable operation of the AVR32UC MC running on Zephyr OS and resolve power-related instability issues, which prompts: System resets unexpectedly.? I have tried monitoring system stability and handling unexpected resets with the following code

#include <zephyr.h>
#include <device.h>
#include <drivers/gpio.h>
#include <sys/printk.h>

void main(void)
{
    printk("System initialized successfully.\n");

    while (1) {
        // Placeholder for main operation code
        printk("System running...\n");
        k_sleep(K_SECONDS(10));
    }
}

#include <zephyr.h>
#include <device.h>
#include <drivers/gpio.h>
#include <sys/printk.h>

void main(void)
{
    printk("System initialized successfully.\n");

    while (1) {
        // Placeholder for main operation code
        printk("System running...\n");
        k_sleep(K_SECONDS(10));
    }
}

The AVR32UC MC should operate stably without unexpected resets, maintaining continuous operation as per the application's requirements when successful.

Hey @Dtynin Unexpected resets can often be tied to power supply problems, have you checked the power supply to ensure it's providing stable voltage?. AVR32UC might be sensitive to voltage dips or spikes.

oh yeah, that's true...got into a convo with a friend about it and that was same measures he gave also, thanks friend @Enthernet Code

To ensure stable operation of AVR32UC MC on Zephyr OS and resolve power-related issues: 1. Verify power supply and decoupling capacitors. 2. Check clock configuration and voltage regulator. 3. Monitor current consumption and temperature. 4. Review Zephyr OS configuration and device drivers. 5. Implement error handling and reset reason detection.
