KL630 EVK 執行 Generic Image Inference的錯誤訊息
您好，我在KL630_V01 96board上用 windows PC 上面執行 ./kl630_demo_generic_image_inference_post_yolo
請問何種原因出現以下錯誤訊息，謝謝：
=====================
$ ./kl630_demo_generic_image_inference_post_yolo
connect device ... OK
upload firmware ... OK
upload model ... OK
read image ... OK
starting inference loop 10 times:
inference failed, error = -7 (USB: Operation timed out)
=====================
另外在telnet連線上也會看到以下訊息
[_get_model_info] get model info send fw_info response failed, sts 0
...
[kdp2_usb_companion_image_thread] error !! inf image size (739468) is bigger than buffer size (20480)

Hi RayYu,
請問您有做了哪些改動呢?
收到Kneron 的96 board(KL630_V01_20230313)之後就按照KL630 96board User Manual以及Getting started的流程來操作(https://doc.kneron.com/docs/#plus_c/getting_started/)，簡列操作流程如下供參考：
1.power on reset 96board
2.telnet 192.168.3.10
3. switch to Kneron PLUS(companion)
4.用Kneron DFUT update to "USB boot " and RUN
5.在windows 打開MYSYS2上執行./kl630_demo_generic_image_inference_post_yolo
Hi RayYu,
請問您PLUS是使用哪個版本呢?
也請幫忙提供KL630這端完整的log做查看，感謝!
Hi Nick,
您好，Kneron PLUS用的是kneron_plus_v3.1.1, 在windows上編譯用General example時 cmake 4.0.0(自動安裝)
另外後續更新了96 board firmware SDK 2.5.5後，error code 卻變成102
執行時的LOG如下(MYSYS2+ Telnet (CMD prompt))：

感謝~~
Hi RayYu,
error log是記憶體不足，請幫忙在KL630 user space 下指令"fw_printenv"並貼給我檢查一下，也幫忙確認KL630開機後是否有跑其他程式，可以下指令"ps"查看，記憶體不足推測是跑了多個程式造成。
您好，請參考以下資訊，謝謝~~

Hi RayYu,
在KL630上使用"ps"指令可以看到系統已經啟動了"rtsps"和"hos_stream"（分別為 PID 197 和 198），這些是 IPCAM 的範例程式。這些程序會在開機時自動啟動，是因為系統執行了/mnt/flash/etc/rc.local 這支script。您可以參考 rc.local 的內容，進一步了解 KL630 開機時的執行流程。
針對您目前的需求，如果不需要這些範例程式自動執行，只需要將 rc.local 中的 ./start.sh 這一行註解掉即可。
謝謝Nick 協助，中止 rtsps 與 hos_stream程序，或修改rc.local 後可以執行推論了
