How to use depthai.CrashDump?

Contractor1 · Apr 18, 2023

When I am intentionally crashing a device during runtime (by wrong image manip configuration, or rising some other error) and then after the crash I run this script to check the dump:

import time
import depthai as dai

def process_crash_dump(crash_dump):
    crash_dump_json = crash_dump.serializeToJson()

    # Process the crash dump as needed, e.g., upload to AWS S3
    print(crash_dump_json)

device = dai.Device()

while True:
    crash_dump = device.getCrashDump()
    crash_reports = crash_dump.crashReports

    if len(crash_reports) > 0:
        print("Crash dump found!")
        process_crash_dump(crash_dump)
    else:
        print("No crash dump found")

I do not see any crash dump available:
No crash dump found

{'crashReports': [], 'depthaiCommitHash': '', 'deviceId': '14442C104190E4D200'}
Can you give me an example usage of that CrashDump functionality?

Hi Contractor1 ,
If it's a critical/fatal error, it doesn't produce the crash. If you have IMX378 yoy could set color resolution to SensorResolution.THE_5312X6000, which will crash the camera. Then you can get crash report. Log here:

python .\ColorCamera\rgb_preview.py 
Traceback (most recent call last):
  File "ColorCamera\rgb_preview.py", line 15, in <module>
    with dai.Device(pipeline) as device:
RuntimeError: Device already closed or disconnected: io error
depthai-python\examples> python .\CrashReport\crash_report.py
Crash dump found on your device!
