From the Hexagon SDK documentation: *Dynamic shared objects are required to be digitally signed and then authenticated at runtime before they are allowed to be loaded and executed.* Generating a testsig library is necessary to run the unsigned sample library built from this project. + +If the lack of a testsig library is your problem, you will see errors of the type: +`vendor/qcom/proprietary/adsprpc/src/fastrpc_apps_user.c:169::error: -1: 0 == (nErr = remotectl_open(name, (int*)ph, dlerrstr, sizeof(dlerrstr), &dlerr))` +appearing in adb logcat. + +There are several ways to create the testsig library, the only prerequisite is Python and the correct version of the Hexagon-SDK. The following steps is one way to create this library: +1. Run adb as root: `adb root` +2. Run the command `adb shell cat /sys/devices/soc0/serial_number` +3. Convert the decimal number you get as output to hex +4. Run the python script: `python ${QUALCOMM_SDK}/tools/elfsigner/elfsigner.py -t $(SERIAL_NUMBER_HEX_VALUE)` +5. The output of the python script is a shared library stored in ${QUALCOMM_SDK}/tools/elfsigner/output/testsig-$(SERIAL_NUMBER_HEX_VALUE).so +6. Push the shared library to your device: +``` +adb root +adb wait-for-device +adb remount +adb wait-for-device +adb shell mkdir /system/lib/rfsa +adb shell mkdir /system/lib/rfsa/adsp +adb push ${QUALCOMM_SDK}/tools/elfsigner/output/testsig-$(SERIAL_NUMBER_HEX_VALUE).so /system/lib/rfsa/adsp/ +``` + +After rebooting your device, you should be able to run the sample application. |
