  • Hi Karasu, Sorry for the delay; we're currently looking into the issue with another team, and we'll let you know when we've found out the cause for this issue. Thank you for your patience!
    in Fail to convert the bie to nef due to invalid bit width Comment by Maria Chen July 2022
  • 您好: 是的，也需要將fw_scpu.bin與fw_ncpu.bin燒錄進KL720 (這兩個.bin檔在Kneron PLUS的res/firmware/KL720裡面)，然後把.nef檔放在models的資料夾裡，再改example的KL720DemoGenericInference，這樣就可以進行姿態偵測了。

  • 您好: 問題一: Kneron-mmpose 具體流程您可以參考: https://github.com/kneron/kneron-mmpose 裡面有 Tutorial-Kneron Edition 給您參考: rsn18_hand_pose_step_by_step.md Tutorial 內有 .nef 使用教學，與如何產生出自己的 .nef。 幫您釐清一下，使用 top_down_img_d…

  • 您好: 問題多沒關係，不用不好意思! 因為有很多東西，第一次使用都會覺得複雜。 問題一: 是的，如果要用GPIO來控制LED的話，需要寫firmware然後轉成bin檔。編寫firmware需要透過ARM的套件Keil C來編譯，沒辦法使用python。 問題二: 只要能夠觀看serial port data的term…

  • 您好， 問題一: 不好意思請問一下，您現在想要寫Kneron PLUS上的程式(用C或Python寫)，還是firmware (KL720 SDK 1.5.0)的程式(用C寫)呢? 是跟上面所說的LED有關係嗎? 如果要寫firmware的程式的話，會需要使用keil C並且需要購買付費授權，才能用keil輸出.bin檔。 問題…

  • 您好， 是的，可以在KL720 firmware的程式裡修改東西。如果想要開發自己的AI模型，才會需要轉成.nef檔。 關於GPIO的應用，這裡有提到KL720 SDK的build資料夾裡面有一些範例可以給您參考。 SOC Peripheral Drivers - Document Center (kneron.com) https://www.kneron.c…

  • 您好， 問題一: 要控制LED的話若只是要開關可以透過GPIO來控制，KL720有很多隻GPIO，但開發版上沒有現成GPIO接LED的設計，需要額外將選定的GPIO接到自己的LED上。 問題二: 這個也可以。uart有兩組，uart0跟uart1。

  • Hi, Unfortunately, we currently don't have a function that draws numbers/words. If you really need it, you'll have to write your own text library inside KL520 for converting your numbers/words into pixels, then modify the code in the display driver …

  • Hi Myron, https://www.kneron.com/forum/uploads/398/MURXJWWHASV7.png After downloading Kneron_DFUT_raspberry_pi_1.3.0 in the development center, please go inside the Kneron_DFUT/bin folder, then try running the Kneron_DFUT program by entering the ./K…
    in Segmentation fault running KneronDFUT Comment by Maria Chen April 2022
  • Hi Myron, Sorry for the late reply, and I'm glad you've figured it out. Yes, you'll need to download Kneron PLUS first, then go to the package directory in the python folder, then run the command to install the API. More information could be found h…

  • Hi Mason, That's good to hear! We don't have the exact schedule for the toolchain update, but our teams are working on it.
    in 4-channel Model Inference with KL720 Comment by Maria Chen March 2022
  • Hi Mason, Thank you for providing the information. Our team ran your code, and we think you could change your alignment for the inference. (Please refer to the code below) The reason why the timeout error occurred is that the NPU input should be 1W1…
    in 4-channel Model Inference with KL720 Comment by Maria Chen March 2022
  • Hi Mason, By "accepting 1, 2, 3, and 4-channel data," could you explain more about it, such as how you noticed that it didn't accept the data in the 5th channel? Also, if the model only accepted the first 4 channel's data, then the problem…
    in 4-channel Model Inference with KL720 Comment by Maria Chen March 2022
  • Hi Mason, Thank you for waiting. According to the hardware team, it seems like one of the model's layers got stuck in the NPU, so the toolchain team will be fixing that bug. You could wait for the updated toolchain to be released, or use your previo…
    in 4-channel Model Inference with KL720 Comment by Maria Chen March 2022
  • Hi Mason, We got your files, and our team found out that the inference flow is stuck in the NPU again. Investigating the root cause inside the NPU would take some time. We'll let you know once we've figured out the cause, thank you for your patience!

  • Hi Mason, Thank you for your information. Could you upload your files onto this sharepoint folder via the below link? We'll perform testing on our side as well. 20220308 Please let us know if you couldn't upload your files here.
    in 4-channel Model Inference with KL720 Comment by Maria Chen March 2022
  • Hi Mason, Could you check the ioinfo.csv file for the NPU input format? Usually, when there are 4 channels, it should be able to run properly with the input 4W4C8B, and 1W16C8B would be more likely to cause errors. https://www.kneron.com/forum/uploa…
    in 4-channel Model Inference with KL720 Comment by Maria Chen March 2022
  • Hi Myron, Kneron supports Raspberry Pi 4, so you should be able to install the dependencies even though our document says 32-bit. Could you let us know what parts are incomplete or if you are having any troubles? We could help you in this thread.
    in MyCroft Comment by Maria Chen February 2022
  • Hi Mitsuhiro, a) KL720 SDK v.1.3.0 should support YOLOV3_608_MODEL (YOLO_V3_608_608_3). I've also tried to run "./kl720_cam_isi_center_app 0 20 210" on host_lib 1.0.0 using a KL720 board with SDK v1.3.0 firmware, and it showed some blue sq…
    in SDK v1.3 and host_lib Examples Comment by Maria Chen February 2022
  • Hi, There are a few ways you could implement lookup tables, but it depends on your environment. How are you planning to use the lookup table? Are you planning to use Kneron PLUS?
    in Can use lookup table on KL520? Comment by Maria Chen January 2022
  • Hi Oded, No worries, there's no need to convert anything. You can use 24bit model as well. When it is being converted using the toolchain, it will automatically fit the NPU format (RGBA8888). You will need to input the right parameters for pre-proc…
    in RGB 24-bit support Comment by Maria Chen January 2022
  • Hi Kendrick, 因為SDK架構的更動，95MB為舊數據，經過一些驗證，新架構的模型上限將會下調 (建議不超過75MB)。 至於讓模型變小的事情，建議直接在網路上找比較小的openpose的model，也可以參考這個網站來做pruning: https://github.com/ChrisAllenMing/pruned_lightw…

  • Hi Albert, Unfortunately, the current Kneron_DFUT (v1.2.0) only supports Raspberry Pi 4, Windows, and Ubuntu. There will be a new version of Kneron PLUS, estimated to be released at the end of the month. In that version, there will be a file you co…

  • Hi Bo-Chen, 有，可以把host_lib的firmware放在Kneron_DFUT裡適當的路徑下，再用以下的command: $ sudo ./KneronDFUT --kl520-update --port {port ID} --scpu {SCPU_FILE_PATH} --ncpu {NCPU_FILE_PATH} 這個沒有在文檔裡面，不過可以用來將KDP2 firmware變回KDP firm…
    in KL520 firmware downgrade Comment by Maria Chen December 2021
  • Hi Oded, Have you updated firmware to your flash? Have you modified your scpu file, and if so, could you provide it? What example were you running when you ran into the error? We could help you debug if you could provide the firmware and PLUS exampl…
    in Error 100 with a customized example Comment by Maria Chen December 2021
  • Hi Kendrick, 這個error的原因有可能是因為.nef檔太大。雖然沒有超過上限，但是firmware的更動有時會影響model能用的空間大小，所以可以請您試著讓.nef檔變小一點，在測試看看嗎? 或是能不能請您提供.nef模型和KL720_Openpose_inference.py，我們可以試著調整設定然後…
    in Got Error When Trying to load openpose model into KL720 Comment by Maria Chen December 2021
  • 還有，請問一下有用 sudo ./scan_devices執行嗎? 另外，可以試著以管理者權限創建 (或開啟)檔案 /etc/udev/rules.d/10-local.rules (若不是用管理者權限開啟的話無法存檔)，在檔案中加入下面三行: SUBSYSTEM=="usb",ATTRS{idVendor}=="3231",ATTRS…
    in windows 使用 MSYS2 執行Kneron_DFUT產生錯誤 Comment by Maria Chen December 2021
  • Hi， 想跟您確認一下，您有下載 libusb-1.0-0-dev嗎? https://www.kneron.com/forum/uploads/245/J5VZJLQAR98E.png
    in windows 使用 MSYS2 執行Kneron_DFUT產生錯誤 Comment by Maria Chen December 2021
  • Hi, 好的，請試試看把Kneron_DFUT/lib/libc.so.6從lib資料夾拿出來，再試著執行一次，因為libc.so可能與這個raspberry pi不相符。這樣，它就會用系統裡的libc.so.6。 如果還是不能執行的話，請再回覆，謝謝!

  • Hi, 程式記憶體區段錯誤有很多種原因。請問一下，您下載的Kneron_DFUT是raspberry pi的版本嗎? Kneron_DFUT_v1.2.1是ubuntu用的，所以可以在archives下載raspberry pi的1.2.0版本。 https://www.kneron.com/forum/uploads/313/HOMYXBM6O8IT.png 如果還是不能執行的話…
