無法上傳 MODEL 至 kl520

上傳模型時遇到此問題，使用預設範例就會出現這個問題，520 使用 usb 加速棒

Hi Johnson,

可以跟您請教一下您的OS版本嗎 (Windows, Linux, etc.)? 還有，您的KL520的USB加速棒是如何與您的電腦連接的呢? 您的電腦現在有連接著很多其他的東西嗎?

因為load model時會再次與KL520加速棒連接，這時如果連接速度太慢，有可能會造成這個error。

P.S. 請問一下，您有修改範例程式或模型嗎? 如果有的話，麻煩您提供程式給我們作為參考，謝謝!

還有，可以請您提供ScanDevices.py的結果嗎? 我們會需要確認device boot-mode。

只有接著 520 與 Webcam

Hi Johnson,

謝謝您提供的資訊! 我們看了您提供的程式。

在KL520上，需要先跑load_model_from_file (下面被註解掉的地方)，才能跑get_model_info，因為usb-boot upload fw會洗掉DDR上的所有資料(包含模型)。

還有，usb_port_id需要確認是否有給，如果給0 (預設)的話，會找不到device。您之前跑ScanDevices.py的結果，port ID是9 (之前是17?)，所以可以設定usb_port_id=9或17，請參考ScanDevices.py的USB port ID。
