I have a 2 imx678 hires cameras attached to a voxl 2 mini the stream video using the voxl-camera-server without any problems, however there is a weird color tint on the cameras. Is there any way to adjust to color calibration for the voxl-camera-server? If not is there a way to access the raw8 or raw10 grey video without any image processing done to them?

RE: J19 uart
@tom I thought I did but it wasn't in properly I tested it again and I got sucess.
so this confirms that uart is working correct? and then for using it in my own program I could use the same things I see in the test program with #include <voxl_io.h> and then all the same voxl_uart functions used in the program yeah?
Thanks. -
RE: IMX 678 Camera Color Problem
@Moderator Any update on accessing the RAW8 for the hires image sensors?
Also, is there a way to change the exposure and gain manually. In the voxl-camera-server config I have been able to change the setting of ae_mode to off and I've tried using the "voxl-send-command hires0_small_color set_exp_gain 100 200" for example but nothing changes. I also tried setting the ae_mode to lme_msv but changing the settings in the config had no effect of the exposure or gain either, it was acting the same as the off mode. Are these settings available to the hires imx678? If not, is there any way for me to adjust the exposure and gain settings?

RE: Imu temp calibration
@Alex-Kushleyev
it runs for about a minute and it seems to be stressing the cpu but not enough to raise the temp significantly, in my setup the voxl is sitting in a metal housing so does it just not get hot enough for it to run the calibration properly?

Imu temp calibration
Hello, I have a voxl2 mini that I'm doing development on and I'm running in to issues with the temperature calibration on the imu, mostly that I can't get it to work. When I try to run the calibration it doesn't complete and says "not enough samples, need at least 3" It feels like I'm missing something obvious but I've tried it a few times to the same result. Any help or guidance is appreciated.

J19 uart
I am trying to access the uart port QUP7 on pin 10/11 on J19 on my voxl2 mini as specified is available in
https://docs.modalai.com/voxl2-linux-user-guide/#slpi-prochowever I'm not sure I understand exactly how to do that, I know I'm supposed to use libqrb5165-io but I don't really know how. I tried using it and I keep getting this as the output and I was hoping for some clarification on how to enable uart on the port
I'm on sdk 1.1.1

RE: Cameras only work in certain ports
@Moderator ok, is this the most up to date list for the voxl2-mini? I'm on SDK 1.1.0 and that page only has up to 1.0.0. Is it possible to have 2 imx678 working off of port J6? I can only get one working on the lower connection but not the one on the upper connection.

Cameras only work in certain ports
Hello,
I've been testing various camera setups for the Voxl 2 mini and have run into problems with certain cameras not working in certain ports and was hoping I could get some clarification if I am missing a setting or if the cameras just aren't compatible with certain ports.First setup: 2 hires IMX678 cameras plugged into the M0084 dual camera adapter with a M0135 interface board. (SDK 1.0.0)
With this setup I was only able to get the cameras to show up when connected to port J7, but my understanding from this (https://docs.modalai.com/voxl2-mini-image-sensors/#hires) is they should work in either J6 or J7 but when plugged in to J6 they don't show up at all under voxl-camera-server -l.Second setup: 1 OV9782 plugged into M0008 with a M0076 (SDK 1.1.0)
This setup only work with the camera plugged into port J6 and was not recognized plugged into port J7.
Third setup: 1 tracking OV7251 (M0014) into a M0076 (SDK 1.1.0)
This camera only work in port J7 with 0 cameras recognized on port J6
If possible I would like to be able to use either port for the cameras so anything you can point me to or any info is appreciated.
