Found the offset
its gpiochip1100
so for gpio 12

echo 1112 > /sys/class/gpio/export

will enable gpio 12

@tom Thank you so much for you help! I got my code to deploy to the voxl! Now on to bug fixing!

@wilkinsaf Thanks for the feedback

@Vinny Thanks! I will have to get one of these boards and then see how we might do the integration. This might require a company like ConnectTech 🙂

@Hersch-Nathan A quick google gave me:

sudo apt update sudo apt install python3-opencv

@Anubhav Great!

@Jyotish-Kumar There could've been an ESD issue induced by not having the board on an ESD mat or not using proper ESD protection, check out https://www.modalai.com/pages/rma

@Chad-Sweet You are correct. Swapped the IMX214 for a different one and it worked. Thank you for the help!

@relevinsky You're right, we are going through an overhaul of the docs at the moment, here's an archived link: https://docs.modalai.com/voxl-logger-0_9/

@tom Thank you for the info.

We have custom drone designed with Carbon fiber chamber inside which voxl2 resides over a dampner platform and we have camera bay towards front of the UAV which has CSI connection with VOXL2. We do not have fan over VOXL2 but we have kept fan towards backside of this carbon fiber chamber to act as exhaust but I guess it isnt working out well to cooldown CPU.

@afdrus No I haven't.😟

@Aaky What format is that logs file? Is it an archive?

@Moderator
That port is capable of providing 2A at 5V from a SW controlled GPIO (GPIO_157).
I'm surprised you would experience a brown-out from a USB to ETH adapter.
On Voxl2, we provide a 10uF and a 1uF cap right at the 60-pin J3 connector.
If you are doing a custom adapter, and to meet USB3 specs, you should not need much more capacitance.

However, if you have a long length before your mating connector, a good 10-22uF would be wise.
We provide a 100uF cap on all of our USB ports that mate to Voxl2 (M0090 5G Modem Plug-in card, for example), but it is also due to a USB switch to help manage the ON time during enumeration.

Back to your specific issue, I would double check you are not toggling GPIO_157, or that your connection is solid and not intermittent.
I cannot find specific ETH dongle power consumption specs online, but it is likely using a LAN7801 or similar type device plus a PHY, which would not exceed more than a few hundred mA combined with magnetics:

So a brown out does not seem likely here. Even a 500mA USB2 rated device has no issue powering these types of dongles.

@tom Thank you for your response! I'll look forward to the new documentation when it becomes available, thanks for the hard work. Cheers!

@James-Strawson Thanks for reply, Will look into it and get back.

@Vinny Ah I did not know that. Thank you for informing me, I will not put PCBs on ESD bags anymore. I don't want to risk breaking any boards

Also, it turns out that the 2023 model of doodle radio has a separate port for power and USB. So we chose to power the doodle separately instead of daisy chaining one port on the VOXL2 to two ports on the doodle.

@Tjark I would estimate 2 months although we may do an intermediate release that only supports RC options (Not PWM) on the IO board in about a month.
