# Development Notes
|
|||
|
|
|
|||
|
|
* First get [repo_pull.py and gerrit.py](https://android.googlesource.com/platform/development/+/master/tools/repo_pull/) 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](https://android.googlesource.com/platform/development/+/master/tools/repo_pull/#installation) steps if necessary.

## Build
|
|||
|
|
|
|||
|
|
Build Android:
|
|||
|
|
|
|||
|
|
```sh
|
|||
|
|
source build/envsetup.sh
|
|||
|
|
lunch qemu_trusty_arm64-userdebug
|
|||
|
|
m
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Build Trusty:
|
|||
|
|
|
|||
|
|
```sh
|
|||
|
|
./trusty/vendor/google/aosp/scripts/build.py qemu-generic-arm64-test-debug --skip-tests 2>stderr.log
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## Trusty PORT_TEST
|
|||
|
|
|
|||
|
|
On QEmu:
|
|||
|
|
|
|||
|
|
```sh
|
|||
|
|
./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)
|
|||
|
|
|
|||
|
|
```sh
|
|||
|
|
/vendor/bin/trusty-ut-ctrl -D /dev/trusty-ipc-dev0 "com.android.trusty.stats.test"
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
On device, in a loop:
|
|||
|
|
|
|||
|
|
```sh
|
|||
|
|
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:
|
|||
|
|
|
|||
|
|
```sh
|
|||
|
|
./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)
|

|
|||
|
|
```
|
|||
|
|
|
|||
|
|
On device, in a loop:
|
|||
|
|
|
|||
|
|
```sh
|
|||
|
|
cat << 'EOF' > metrics-nw.sh
|
|||
