@Huynh-Gremsy You cannot connect peripherals to the USBC port in that way, you'll have to use one of our add-on boards that breakout USB ports

@mrawding good afternoon, i see that your topic is quite old, but I am struggling with px4 firmware build and was wondering if you ever managed to successfully build your px4 firmware ? If you have done it recently, I would appreciate a helping hand in this topic: https://forum.modalai.com/topic/4539/voxl2-hitl-sim-with-gazebo-in-docker-vtol-frame-support/13?_=1751379111988

@vjuliani , the tracking camera ( i assume ov7251 or AR0144) is monochrome, so you can not make the image colored. You can install the latest version of the voxl-streamer from dev (nightly builds) http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/ and it should allow you to encode h265. Alex

Hello @selina, Do you have any px4 logs from the original flight(s) which exhibited the flipping behavior? The logs contain the commanded and actual RPM (as well as many other things) and we can check what happened. If you don't have any sensitive information (gps location that you dont want to share, etc), you could upload the log to https://review.px4.io/ and that will give you some information and we will be able to grab that log and further analyze it to parse the custom ESC messages that standard px4 flight review does not support. Alex

@Alex-Kushleyev Dear Alex, It's the M0025-002 high resolution camera. Perhaps the connection sodder was loose and it popped off real easily. In hindsight, perhaps it's not worth anyone's time. If you can provide any repair tricks that'd be neat otherwise I'll probably have to send a new order in. Best, Milton

@tom After flashing, I cannot connect to the QGC. After setting up the IP address, I try to connect via UDP using the IP and port 14550, this is what I get [image: 1740736258690-e032a3a6-32d8-4b3f-9f56-dba442f9aaa4-image.png] drone(connected) is the one not connecting to QGC.

@Amin-Bassiri You can either fully re-flash the drone or just run voxl-configure-mpa in order to bring the drone back to it's default state based on the SKU

@kham https://www.modalai.com/products/m10000045?_pos=1&_sid=0d63c4c00&_ss=r

@smilon The parameter EKF2_REQ_SACC sets the maximum allowable speed accuracy. If you increase that value does the warning go away? Can you post a log?

Did the trick btw

@tom Thank you very much.

@Vinny Still no luck. Went in to RB5 images UFS folder. Attached power to J4 and then USBc. Launched the command.

@Alex-Kushleyev After running "voxl-configure-px4-params --platform MRB-D0006" to configure RB5 PX4 parameters, I could perform an outdoors flight with RB5 using Position Flight Mode without GPS or motor problems: https://youtu.be/D8zP0hOx8wc It seems that the issue was RB5 running with Sentinel PX4 parameters after SDK upgrade. Thank you for your help
