Common Issues & Troubleshooting

Q1: After the device runs high-load workloads, the system restarts automatically. Which items should be checked first?

1. Temperature: High load can raise the temperature and trigger hardware overheat protection. Check the dmesg / thermal logs to confirm that heat sinks, fans, and other cooling components are working properly.
2. Power: Peak power consumption at full load may cause voltage drops. Measure the power supply waveform at full load; you can cross-validate by replacing with a higher-power adapter.
3. Memory, firmware, and hardware faults: If neither temperature nor power shows any anomaly, further check memory stability (memtester), whether the firmware version matches, and whether the hardware has physical damage or poor contact.

Q2: How can I check 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
