Segmentation Fault when running mynteye_wrapper_node

[nicotho]

Hi,

When starting the mynteye ros node under Ros Melodic the node stops with a segmentation fault after advertizing service get_info. I have compiled the SDK v2 and my camera config is

device_name: MYNT-EYE-S1030 serial_number: "0507151500090721" firmware_version: "2.2" hardware_version: "2.0" spec_version: "1.0" lens_type: "0000" imu_type: "0000" nominal_baseline: 120

After some ROSINFO debugging I found out that the node crashes when invoking api_->Start(Source::ALL); in the function void publishTopics() of wrapper_nodelet.cc

Thank you for your support. Nicolas

When you run samples output bin\ api\ camera_a, do you have similar problems?

[nicotho]

Hi, I have no issue running camera_a. I let it run for over an hour without any issues....

I'm sorry I didn't notice your reply before. Do you have any problem under ROS now?

@KalmanXiong Hi,

Unfortunately my problem persists. How do we proceed? Is there anything I prepare in order for you to Debug the situation? Thanks, Nicolas
