NVIDIA Jetson Nano 出貨測試程序

測試環境

測試方法

依據 Jetson Nano Style – Serial Console 中的接線方式,將 console debug message 導出紀錄。裝置上有些模組可能未經初始化或其他未連接周邊等原因,可能會回報錯誤。基本上不必擔心,只要看到一路順利開到 console login prompt 就是 OK!

參考資料

  • console debug message 中看到的 serial number 與底板印刷並不一致,這是個存在已久的老問題,NVIDIA 在Serial number mismatch 中解釋底板硬體並未儲存序號,軟體讀取的是 EEPROM 的序號,但是 EEPROM 是可以修改的... So... 不過不建議亂改,因為有 CRC 錯誤的風險,有可能會導致 Jetson Nano 變磚。
  • NVIDIA Jetson Nano 開機故障排除 列舉一些開機相關資訊。

console debug message 範例

後附上第一代 Jetson Nano 4GB 開機 console debug message,可以看到某些模組(主要都是一些記憶單元的樣子)會回報錯誤。
