Development Notes
-
First get repo_pull.py and gerrit.py from aosp.
-
Although this repo is not currently in Trusty’s manifest, it’s sufficient to copy these two python scripts to the root of the Trusty project and run them from there. Make sure to follow the repo_pull installation steps if necessary.
Build
Build Android:
source build/envsetup.sh
lunch qemu_trusty_arm64-userdebug
m
Build Trusty:
./trusty/vendor/google/aosp/scripts/build.py qemu-generic-arm64-test-debug --skip-tests 2>stderr.log
Trusty PORT_TEST
On QEmu:
./build-root/build-qemu-generic-arm64-test-debug/run --headless --boot-test "com.android.trusty.stats.test" --verbose
On device: (Build for your device's debug target on both Adroid and Trusty)
/vendor/bin/trusty-ut-ctrl -D /dev/trusty-ipc-dev0 "com.android.trusty.stats.test"
On device, in a loop:
cat << 'EOF' > metrics.sh
#!/system/bin/sh
TIMES=${1:-0}
X=0
while [ "$TIMES" -eq 0 -o "$TIMES" -gt "$X" ]
do
echo "######################## stats.test $X " $(( X++ ));
/vendor/bin/trusty-ut-ctrl -D /dev/trusty-ipc-dev0 "com.android.trusty.stats.test"
done
EOF
adb wait-for-device
adb push metrics.sh /data/user/test/metrics.sh
adb shell sh /data/user/test/metrics.sh
Android Native Test
On QEmu:
./build-root/build-qemu-generic-arm64-test-debug/run --headless --android $ANDROID_PROJECT_ROOT --shell-command "/data/nativetest64/vendor/trusty_stats_test/trusty_stats_test" --verbose
On device: (Build for your device's debug target on both Adroid and Trusty)
/data/nativetest64/vendor/trusty_stats_test/trusty_stats_test
On device, in a loop:
cat << 'EOF' > metrics-nw.sh
#!/system/bin/sh
TIMES=${1:-0}
X=0
while [ "$TIMES" -eq 0 -o "$TIMES" -gt "$X" ]
do
echo "######################## stats.test $X " $(( X++ ));
