FAQ & Troubleshooting

Q1: The device restarts automatically after running high-load workloads. What should I check first?

1. Temperature: High-load temperature rise may trigger hardware thermal protection. Check dmesg / thermal logs and verify that cooling accessories such as heatsinks and fans are functioning properly.
2. Power: Peak power consumption under full load may cause voltage drops. Measure the power supply waveform under full load and cross-validate by swapping with a higher-wattage power supply.
3. Check memory, firmware, and hardware failures: If both temperature and power are normal, further inspect memory stability (memtester), whether the firmware version matches, and whether there is any physical damage or poor contact on the hardware.

Q2: How do I view the real-time frequency of each module?

• CPU:

  cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq

• NPU:

  dsp_mon --all

• GPU:

  cat /sys/kernel/gpu/gpu_clock

• DDR:

  cat /sys/devices/system/cpu/bus_dcvs/DDR/cur_freq
