@gauravshukla914 I also noticed it. Somehow on the drone's ROS indigo system. roslaunch voxl_mpa_to_ros voxl_map_to_ros.launch won't honor the existing ROS_MASTER_URI, it always source ROS_MASTER_URI etc from my_ros_env.sh

After multiple tries, the fastboot start to flash system images. But it got stuck. We then power cycle again, this time everything worked. We got the new nightly build flashed.

Thanks!

Looks like we need to press some physical button. I'll ask my coworker to open the heat sink again

The system is just recovered by using qdl, voxl-version shows

I tried to flash it with voxl2_platform_nightly_20230521

Thanks!

@Dong-Liu Even I power on the voxl2 with usb cable connected, I get the same error.

Re: Can't Flash VOXL2 (Battery Capacity is Very Low)

The same issue with the reference post.

I followed the instruction that power on the voxl2, wait for 10 seconds, connect the USB cable. But I got

[WARNING] Failed to reboot to fastboot
Try power cycling VOXL while holding the fastboot button

We're running the voxl2 with a power adapter, no battery is used.

Just tried to calibrated the stereo camera using ROS camera calibrator. Had to run the fixed voxl-mpa-to-ros. Because the ROS calibrator expects left and right to be exactly synchronized.

MR submitted.

will do soon.

Here is the code,

imgL.header.stamp = (_clock_monotonic_to_ros_time(meta.timestamp_ns));
imgL.width    = meta.width;
imgL.height   = meta.height;
imgL.step     = meta.width;
imgL.encoding = GetRosFormat(meta.format);

imgR.header.stamp = (_clock_monotonic_to_ros_time(meta.timestamp_ns));
imgR.width    = meta.width;
imgR.height   = meta.height;
imgR.step     = meta.width;
imgR.encoding = GetRosFormat(meta.format);

They are all from meta.timestamp_ns, but _clock_monotonic_to_ros is using the current time, so the final times are slight different.

I think it should be
imgR.header.stamp = imgL.header.stamp

I extract the findJpegSize function, add to voxl-camera-server. Now it will produce the correct size snapshot.

Found the problem

The voxl-docker script mount host /data to the container /data. But voxl-cross image has its own /data folder where /data/offline_ipk_packages/apq8096-proprietary_0.0.4.ipk is stored.

Remove the -v /data:/data from voxl-docker script, start the docker again. This it works!
