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?

@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.

@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?

@Vinny I was able to get it in fastboot mode and flash it so things seem to be working now, switching to off and hitting the button solved it.

Thanks for all the help!

@Vinny It wasn't a power issue, I realized one of the boards in the stack wasn't connecting properly, so pretty simple to fix that.

I am still having the issue of actually getting it to work though, all of my attempts to get it into fastboot mode don't do anything and there doesn't seem to be a button on the board I can push and the switch doesn't seem to be helping. There is a button on the 5G Wireless board at the top, but this also does not seem to put it into fastboot mode. I also can't connect to it any other way, like just doing adb shell and no devices show for adb devices nor fastboot devices.

@mkriesel I got the green light now but there is still a problem, the 5G boaard has a button but the bottom 2 boards don't have any button, just the switch on the middle board, the one with the usb connector. I still cannot connect to it nor get fastboot working.

@tom Hello, I am picking up this problem now and have some questions about what I should do for next steps.

There are 2 boards in this stack and it seems slightly different than than the stock Voxl 2. On the top board there is a button labeled sw3. Pressing this button and power on does not seem to be enabling fastboot mode. the install.sh script just hangs and fastboot devices produces no results. There is a switch labled sw1 but this does not seem to do anything either and I can't seem to find what this does.

What do you mean by "light being red is not good", what does this indicate? Power to the board seems fine. I'm using the stock cable an wall power adapter and everything seems to turn on fine and is supplying the correct power.

Are there other things I can try or would this board need to be sent back for fixing

@Alex-Kushleyev Alright, thanks for the info

@Alex-Kushleyev Hi again, I'm now testing similar capability for the OnSemi AR0144 https://docs.modalai.com/M0149/ but looking at the debug logs I see

DEBUG: setting thread affinity for cam hires preview
DEBUG: hires checking to see if it is raw8 or raw 10
DEBUG: Frame was actually 8 bit, sending as is
DEBUG: Value of standby_active is: 0

so does this mean that I cannot get 10 bit imagery from this sensor? I see messages like <pre><font color="#839496"><b> </b></font>Allocated BO with width=1280 height=800 stride=1600 aligned_w=1600 aligned_h=800 size=1282048 flags=0x20900 format=GBM_FORMAT_RAW10
</pre> as well. I'm just trying to figure what options I have available for this sensor right now.

Thanks!

@Alex-Kushleyev Hi, I got the chance to test this over the past few days. It working and I haven't run into any issues so far. Thank you very much for helping out this this.

@Vinny Thanks for the help on this I really appreciate it. I'll take a look.

@Alex-Kushleyev Hi Alex, wondering if you have an update for me on this, thanks.

@Eric-Katzfey I undertand you do not have any Voxl 2 mini schematics open to the public but is it possible for you to share with me the gpio pins that J19 are on for the QRB5165 board?
