# Compile and install Qualcomm IM SDK plugins This section explains how to compile a Qualcomm IM SDK plugin and install it on the device, using the `mlvdetection` plugin as an example. 1. Setup the environment: cd $ESDK_ROOT Copy to clipboard source environment-setup-armv8-2a-qcom-linux Copy to clipboard SDK environment now set up; additionally you may now run devtool to perform development tasks. Run devtool --help for further details. [/local/mnt/workspace/QIMSDK_ESDK_6490/workspace/sources/qcom-gst-ai-classification]$ Copy to clipboard 2. Download the Qualcomm IM SDK plugin source code. cd $ESDK_ROOT Copy to clipboard devtool modify qcom-gstreamer1.0-plugins-oss-mlvdetection Copy to clipboard Where `qcom-gstreamer1.0-plugins-oss-mlvdetection` is the bitbake recipe that downloads the source code for the plugin.

Copy to clipboard 4. Generate the plugin installer (`.ipk`) to install the application on the device. devtool package qcom-gstreamer1.0-plugins-oss-mlvdetection Copy to clipboard Verify that the installable package is present at the following path. ls $ESDK_ROOT/tmp/deploy/ipk/armv8-2a | grep qcom-gstreamer1.0-plugins-oss- mlvdetection Copy to clipboard qcom-gstreamer1.0-plugins-oss-mlvdetection_1.0-r0_armv8-2a.ipk qcom-gstreamer1.0-plugins-oss-mlvdetection_dbg_1.0-r0_armv8-2a.ipk qcom-gstreamer1.0-plugins-oss-mlvdetection_dev_1.0-r0_armv8-2a.ipk qcom-gstreamer1.0-plugins-oss-mlvdetection_src_1.0-r0_armv8-2a.ipk [/local/mnt/workspace/QIMSDK_ESDK_6490/workspace/sources/qcom-gstreamer1.0-plugins-oss-mlvdetection]$ Copy to clipboard 5. Setup an SSH connection with the device by following the steps [here](https://docs.qualcomm.com/bundle/publicresource/topics/80-70017-254/how_to.html#use-ssh). Once connected, the RB3Gen2 device is accessible through its configured IP address. 6. Copy the `qcom-gstreamer1.0-plugins-oss-mlvdetection_1.0-r0_armv8-2a.ipk` to the RB3Gen2 device to install the compiled reference apps. 7. Connect to the device through the SSH shell: ssh root@ Copy to clipboard Note If prompted, enter `oelinux123` as the password for the SSH shell. 8. Run the following command on the target device. mount -o remount,rw / exit Copy to clipboard 9. Run the following on the host computer: cd $ESDK_ROOT/tmp/deploy/ipk/armv8-2a/ Copy to clipboard scp qcom-gstreamer1.0-plugins-oss-mlvdetection_1.0-r0_armv8-2a.ipk root@:/opt Copy to clipboard 10. Connect to the device through the SSH shell: ssh root@ Copy to clipboard 11. Run the following on the target device: opkg --force-depends --force-reinstall --force-overwrite install /opt/qcom- gstreamer1.0-plugins-oss-mlvdetection_1.0-r0_armv8-2a.ipk Copy to clipboard 12. Verify that IPK installation is successful as shown below: Installing qcom-gstreamer1.0-plugins-oss-mlvdetection (1.0) on root Configuring qcom-gstreamer1.0-plugins-oss-mlvdetection.
