Hi Thao, Where are the nef files from, are they generated by the Kneron toolchain, or somewhere else? Adding onto that, if you generated the .nef files using the Kneron toolchain, you should be able to combine them together into an .nef file. It wou…

Hi, 不好意思，我們的toolchain不支持動態輸入尺寸，所以跑toolchain之前需要先設定好解析度。

in 動態輸入尺寸 Comment by Maria Chen May 2023

您好，順帶一題，如果要用KNERON_FD_MASK_MBSSD_200_200_3來做inference的話: -可以把KNERON_FD_MASK_MBSSD_200_200_3的model (models_520.nef) (在Kneron PLUS的models的ssd_fd_lm裡面) 放在firmware/utils/bin_gen/flash_bin裡面 (原本裡面的model_520.nef是TINY_YO…

您好， KL520_SDK裡面的models_520.nef裡面只有包含TINY_YOLO_V3_224_224_3，沒有KNERON_FD_MASK_MBSSD_200_200_3，所以host_mipi會跑不起來(如果用UART console，可以看到會顯示scpu error)。還有，send_to_inference_queue()裡面的total_size是yolo的格式，而demo_c…

您好，可以在Zadig的Options勾選List All Devices，應該就可以看得到KL520的dongle (unknown device)了。如果沒看到，請再跟我們說，謝謝! https://www.kneron.com/forum/uploads/538/FCBR8XCQQ5OJ.png

Hi Alan, 謝謝您提供資訊! 如果用Windows跑也會失敗的話，就不是Linux的問題了。我們會建議您的dongle用super speed來跑inference會比較好! (因為太慢會inference timeout) 可以再麻煩您重新燒firmware (fw_scpu.bin跟fw_ncpu.bin)到KL720的dongle上，再試著跑inferen…

Hi Alan, 謝謝您提供資訊! 如果用的是開發板，可以將UART接出後透過teraterm或putty等終端機程式確認firmware版本。如果用的是KL720 dongle，可以用GenericCommand.py --target KL720來查看firmware版本: https://www.kneron.com/forum/uploads/735/OHKCPYYNFWHE.png …

Hi Shawn, "Sending data (image) size exceeds firmware buffer size" error是因為您的圖片超過KL520的firmware buffer size。您可以 -試著用比較小的圖片，或是 -參考kl520_demo_generic_data_inference.c，用kp_generic_data_inference_send來繞過這個限…

Hi Jingyuan, 1. Firmware is something that could be uploaded onto your KL520/KL720 device. When you run Kneron PLUS example programs, the software sets the parameters and tells the firmware to continue with the inferencing, and the firmware communic…

Hi Pin, 是有一個方法: 在插著KL520 dongle的時候按dongle上的reset button三下(要有一定的間隔)，再來用scan_devices來找出dongle。失敗的話，再用不同的間隔按reset button三次，再用scan_devices。如果試了很多種間隔都還是不行的話，有可能會需要您寄dongle來給我…
