OK, then I think I understand what happened. The 12V Fan was cooling the MCUs, but since the temperature measurement is done inside the MCU itself, the temperature of Mosfets is not known. In general it is always better to put air flow on the Mosfets, not MCU, because Mosfets produce heat. I think this explains the behavior when MCU was reading about 90C but ESC started behaving strangely -- the Mosfets were likely much hotter and got de-soldered.. Alex

@Aks I don't anticipate any issues running 1.12.31 on platform release 1.0.0

@TPSetati I'd recommend sending it in to us for an RMA so that we can do an inspection: https://www.modalai.com/pages/rma

Around 85c, but the tool will make it really clear when there is an issue

Hi @황인호 we have not integrated with this module yet. For sure the 2-lane MIPI integration has not been done and there's work to make that happen, but the USB3.0 interface 'may' work out of the box, although we've not tried this yet!

VOXL 2 runs an Ubuntu 18 OS, and we're not doing anything special to control networking functionality. Have you looked at the tutorial like this to see if you can configure that way?

Hi @McMason , What's your hardware setup like, image sensor (imx214/412/678?) and flex extensions (none, short M0074, long M0036) and port being used? J7/J8? System image version 1.4.1 or 1.5.5? https://docs.modalai.com/voxl2-system-image/#changelog And what about your setup in /etc/modalai/voxl-camera-server.conf ? Lots of times intermittencies like this are flex related (e.g. length, or kinks or connection), in general we have this setup the IMX214 setup in our Sentinel drone which is running continuously so it's not expected behaviour to crash!

Hi @modaltb, we are having that issue on a certain VOXL2 board. We had an extra Voxl2 we put in and the issue isnt there as expected. Once i get a free moment ill dig back into the problem board. as of now its ok.

Hi @Nathan-Sizemore No, that is a behavior we know about, but does not impact peripheral mode (due to a diode "OR" inside the circuits). We are taken steps to change this behavior on future designs to allow full OTG support. However, Voxl2 M0054 does not have that, and can only function as device/peripheral on that port. When a PC/Host plugs in, the VBUS from that host is then detected by the Power Mgmt ICs (PMICs) to enable proper peripheral mode. We know that this behavior of VBUS is not ideal, but as just mentioned we will improve it later.

@Eric-Katzfey I've been stuck on travel for the past month but happy to report that your solution worked! input_rc is publishing and I was able to calibrate in QGC.

@Tamas-Pal-0 That sounds like a good question for the PX4 community. We don't have any experience flying with a distance sensor but I'm sure others in the PX4 community do this all the time.

@Aks You should be able to run two. But, again, we have never tested.

Because on my voxl2 it seems that neither this configuration nor the 2TOF2 configuration is possible... [image: 1680703429182-screenshot-from-2023-04-05-16-02-47.png]

@modaltb thank you for your answer. For so far I can see my program is the same. I'll take some more indepth look when I'm at work again. Is there some .so file I've got to include in my cmakelist? I've already tried every possible combination that's out there. Hope we can fix this soon.

Outstanding!

That's cool! We have never tried that tool. Do you have instructions or a pointer as to how it works?

I tried adding the .so file to the hellocl example, and got the following error: /usr/lib/gcc-cross/aarch64-linux-gnu/7/../../../../aarch64-linux-gnu/bin/ld: warning: libcutils.so.0, needed by /usr/lib/../lib/libOpenCL.so, not found (try using -rpath or -rpath-link) /usr/lib/../lib/libOpenCL.so: undefined reference to `property_get' and when adding it to our OpenCV application, OpenCV still cannot find any OpenCL devices. I suspect OpenCV needs to be recompiled with the .so file in the docker image. This issue is not immediately pressing, so if you intend to update the voxl-cross image I can wait for that instead of trying to create a fix.
