@Jetson-Nano , 60C is not an issue for embedded devices (throttling limit is around 95C, at which point the CPU will start reducing frequency to avoid overheating). However, you mention that the temperature can reach 90C. Please note that the camera server itself most likely is not the main cause of the CPU temperature, but the consumers of the image frames may be using significant CPU. You should identify the main causes of temperature rise by looking at output of top to see rough cpu usage of each process, but also try disabling mapper or openvins or hires image processing (if any). Also, without any cooling, it is not a surprise that VOXL2 could overheat if its cpu / gpu load is very high. The SoC cannot run without cooling at full power. Airflow during flight usually provides significant cooling and you can manage the system load when not in flight or add cooling for stationary use cases (lack of air flow from propellers), Alex

@KnightHawk What are you trying to do? Why would you want to communicate with your FC via i2c?

@claw That is definitely not the expected behavior, I recommend going through the RMA process

@v_v_ramarao voxl-streamer does not support multicast

Hi @voxltester Apologies you are having issues with the power cable. We have expressed in several forum posts that care must be employed when removing and inserting any power cables to not tug on the cables themselves, but rather the large shroud/connector housing. Pulling on any cable repeatedly will dramatically reduce it's service life as it results in frayed conductors at the pin crimp contacts. This is not an MCBL-00001 issue, but all cables in all electronics not just from ModalAI. There are no plans to change this solution as it has been tried and true for over a decade. Some of my power cables are nearing 13 years old and every one can last that long if handled properly. If needed, I can try to search through some forum posts where I think we have a picture showing the recommended methods of grabbing onto the plastic shroud instead of the cable conductors themselves. Our team is trained on this method as well. Hope this helps.

@swickliff Interesting, have you had success with this hardware setup before?

@kestrelsystemsbp Take a look at Python MPA interface: https://gitlab.com/voxl-public/voxl-sdk/core-libs/libmodal-pipe/-/tree/dev/python?ref_type=heads

Hi @dougmiller If your VOXL 2 Mini is TrustZone Configured for UART over J10, then yes, there are 2 pins available as inputs. https://docs.modalai.com/voxl2-mini-connectors/#j10---external-uart You can see GPIO_40, GPIO_46 and GPIO_64 are input capable. GPIO_40 and GPIO_64 are able to be configured to do wake events in the SoC so they have extra configuration to route to a power manager. Depending on how you write your IRQ routine, that may or may not help. Hope this helps!

@h3robotics , Thank you, you are right again. We will update!

@Eric-Katzfey Thank you! I now use journalctl and write to a file in a logger service, for example: voxl-mapper-logger.service [Unit] Description=Logs voxl-mapper log output to file After=voxl-wait-for-fs.service network.target network-online.target Requires=voxl-wait-for-fs.service network.target network-online.target voxl-mapper.service [Service] Type=simple ExecStart=/bin/bash -c "sleep 45 && journalctl -f -u voxl-mapper.service >> /data/logs/voxl_mapper.log" StartLimitInterval=0 Restart=always RestartSec=2s [Install] WantedBy=multi-user.target

@jacob-yaacubov We have some add-on boards that would allow connection of 2 USB cameras. For example: https://www.modalai.com/collections/voxl-2-add-ons/products/voxl-microhard-modem-usb-hub and https://www.modalai.com/collections/voxl-2-add-ons/products/voxl-lte?variant=32449203601459

@tom Thank you! I am adding an imx214 on J8L.

@Dronodev Using the M0065 on a UART on the WiFi add-on board may be the most straightforward way to do this. We've never tried to set one up like that but, in theory, it should work if configured correctly in px4. There is no direct way right now to send the RC channel PWM input out the VOXL esc PWM output. There are a number of different ways to approach that so we'll take a look and see if we can come up with something in the next couple of weeks.

@Vinny Thanks for all the info.

@voxl-phoenix , this may be a hardware issue because VOXL2 will boot just fine without M0173 camera front end plugged in (if the hardware is OK). It is possible that one of the camera connectors (where M0173 plugs in) has broken off or is loose, causing a hardware failure. If you would like a better diagnosis, please share a video of the voxl2 not booting, so we can see the LEDs (i realize there are green leds on top and bottom, but the way your image shows, you can see both of them. Also, in this non-booting state, does the VOXL2 show up as any USB device when plugged into a linux machine using the main USB C connector? Alex

@astro_phil , unfortunately if the device is not automatically being detected by VOXL2, you may be on your own in terms of building the kernel module for it. Please search the forum for building kernel modules, as some users have tried this. Specifically, this one : https://forum.modalai.com/topic/3841/voxl2-kernel-version/ and maybe a few others as well.
