KL630, Error code: 102.

YANG,FU-SYUAN · August 2024

您好，我在WINDOWS上使用KL630-96Board進行開發

有透過SD卡更新KL630_96board_firmware_sdk2.5.5

我目前嘗試運行Kneron PLUS - Python的範例，在進行推理的範例時都會出現Error code: 102，錯誤資訊如下：

Hi FU-SYUAN,

看起來是KL630的記憶體不足，請問KL630有同時執行其他程式嗎?

請協助在執行python範例時，在KL630執行下面指令並將相關log提供給我這邊替您查看:

1. ps

2. cat /sys/class/vpl_edmc/footprint

3. free -m

謝謝。

您好，執行範例過程中只有執行教學中程序，例如：KneronDFUT、透過telnet連到KL630，都算是外部連線到630，不知算不算占用系統資源，預設也有基本的rtsp串流，但沒有觀看。

以下是執行KL630DemoGenericDataInference.py截取的資訊，再麻煩您協助了，感謝您。

Hi FU-SYUAN,

有注意到您同時執行了kp_daemon及kp_firmware_host_stream，這會造成記憶體不足，

如果您是要跑kneron plus的範例程式，建議重新燒入KL630_96board_firmware_for_kneron_plus_sdk2.5.5.zip的FW，

該FW開機後預設只會執行plus所需的程式，因此不會碰到記憶體不足問題，

請再試試看，如有任何問題請隨時聯繫我們。

謝謝!

您好，我重刷SDK並測試結果還是102，下面是我測試的過程，再麻煩您協助，如我操作有誤再麻煩您告知

我透過KL630_96board_User_Manual.pdf這份文件的 1.15 Firmware Update 透過SD卡完成更新，UART 輸出如附件:

uart.txt

完成更新後，我開機就調出相關log，結果如下：

一開機ps.txt

DRAM 0 Forward allocated size: 61384510 bytes, Backward allocated size: 69771892 bytes, Total allocated size 131156402 bytes

             total       used       free     shared    buffers     cached
Mem:            52         34         18          0          1         15
-/+ buffers/cache:         17         35
Swap:            0          0          0

透過KL630_96board_User_Manual.pdf這份文件的1.9 USB Device – PC (Kneron Plus)與電腦連接，再次調出相關log

連接後ps.txt

DRAM 0 Forward allocated size: 61384510 bytes, Backward allocated size: 69771892 bytes, Total allocated size 131156402 bytes

             total       used       free     shared    buffers     cached
Mem:            52         35         17          0          1         15
-/+ buffers/cache:         18         34
Swap:            0          0          0

執行ScanDevices.py確認設備已連接

執行KL630DemoGenericDataInference.py測試推理

 -  - Error: inference failed, error = Error raised in function: generic_data_inference_receive. Error code: 102. Description: ApiReturnCode.KP_FW_DDR_MALLOC_FAILED_102

這時候調用的log如下：

Hi FU-SYUAN,

根據您提供的資訊應該是KL630燒錯firmware了，請再確認燒入的firmware是這包。

謝謝!

YANG,FU-SYUAN · August 2024

了解了，但我在https://www.kneron.com/en/support/developers/ 找不到相關的檔案

請問我應該在那邊找到該檔案?

Nick Wang · August 2024

Hi FU-SYUAN,

權限問題需要您聯繫最初接洽的業務處理，

或是直接修改rc.loacl如下，修改後重新開機即會自動執行kneron plus所需程式，而不會另外執行host_stream。

# cat /mnt/flash/etc/rc.local 
#!/bin/sh
cd /mnt/flash/vienna/drivers/;
sh driver.sh;
#cd /mnt/flash/vienna/;
#sh ./start.sh;

# "PLUS FW PART"
# enable auto reboot when kernel panic
echo 3 > /proc/sys/kernel/panic
/sbin/watchdog -T 3 -t 2 /dev/watchdog

#echo "plus_init"
sh /mnt/flash/etc/plus_usb_companion_init.sh

可正常運作了，感謝您

KL630, Error code: 102.
