本节主要介绍Quectel Pi M1产品上如何使用NPU进行AI推理，L1没有DSP，不支持NPU使用。

Android

资源包可以 联系我们 获取。

将此包解压后使用adb命令推送进设备。

adb root
adb remount
adb reboot
adb root
adb remount
adb push snpe_242 /data/local/tmp/

DSP验证:
cd /data/local/tmp/
chmod 777 * -R
export PATH=$PATH:/data/local/tmp/snpe_242/snpe_242/bin/aarch64-android
export LD_LIBRARY_PATH=/data/local/tmp/snpe_242/snpe_242/snpe_242/lib/aarch64-android
export ADSP_LIBRARY_PATH="/data/local/tmp/snpe_242/snpe_242/lib/hexagon-v66/unsigned;/vendor/lib/rfsa/adsp;/dsp;/dsp/cdsp"
snpe-platform-validator --runtime dsp

模型推理:
adb shell
cd /data/local/tmp/snpe_242/test-android_242/
export PATH=$PATH:/data/local/tmp/snpe_242/snpe_242/bin/aarch64-android
export LD_LIBRARY_PATH=/data/local/tmp/snpe_242/snpe_242/snpe_242/lib/aarch64-android:/data/local/tmp/snpe_242/test-android_242/lib
export ADSP_LIBRARY_PATH="/data/local/tmp/snpe_242/snpe_242/lib/hexagon-v66/unsigned;/vendor/lib/rfsa/adsp;/dsp;/dsp/cdsp"
./test ./model/yolov5s_242_q.dlc ./image/bus.jpg
