BRD602 ORIN Power On#

Before the startup, the following items should be confirmed.

  • Confirm that the input power supply is DC 9 - 36V.

  • Use connection method 1 or connection method 2 to connect the power supply.

  • After checking that all connections are normal, power on the device.

Connection method 1: Use the power adapter and power transfer cable provided by Miwen to connect to the DC power interface.

Troubleshooting of startup issues#

Phenomenon: The device cannot enter the system after being powered on.#

Check item 1: Check hardware connections#

Step 1: Confirm that the power adapter used meets the power supply requirements of the device#

Taking AD10 as an example, the power supply range is 9-36V, and it can start normally only if the power is at least 35W (no-load). For reference, please refer to the specification sheet:https://doc.miivii.com/Apex-AD10-User-Manual-CH/wiki/Apex-AD10-%E4%BA%A7%E5%93%81%E8%A7%84%E6%A0%BC%E4%B9%A6.html。

Other devices can directly refer to the product specification.

  • If it is confirmed that the adapter meets the requirements, proceed to “Step 2”.

  • If the adapter does not meet the requirements, it is necessary to replace it with an adapter that meets the power supply requirements.

Step 2: Cross-verify the adapter status#

Use the power adapter from “Step 1” to connect other devices that can normally power on and enter the system.

  • If other devices also fail to power on and enter the system normally, it indicates an “adapter failure”, and it is recommended to replace the adapter.

  • If other devices can power on and enter the system normally, it is necessary to perform “Troubleshooting Item 2: Observe the startup log”.

Check item 2: Observe the startup log#

Step 1: Connect to the serial port for debugging#

  • If there is no output at all, it may be a hardware issue.

  • If there is partial startup log but it gets stuck, record the specific error information and send the log to Miwen Technical Support.

    • If you have the conditions to reflash the image, it is recommended to reflash the image to check if it is caused by the software system environment.

  • If you can log in, use df -h to check the hard disk usage, clear redundant files to reduce system usage, then restart and try again.
