@vmayoral
i presume it should work as well with the ODroid since i compiled myself the kernel modules.
adeptastic
@adeptastic
good information!!! thank you

@vmayoral
I quite like this dongle because it can be purchased with different antenas
and it supports 802.11 ac. We are actually using the 5 GHz band. Quite useful when using RC controllers :)

@adeptastic
I think maybe more than description, also showing some kinda control interface, whether its mission planner, qgroundcontrol, or even command line would be helpful to understand how you're interacting or monitoring the missions
heh yeah I find myself considering ezUHF 433mhz RC control just to free 2.4GHz for directional amplified video links

@proficnc I've been looking into the capacitors of the PXF design and i found that some of them have 0.1% tolerances. I've gone through the datasheet of the components they are attached to and i couldn't find a reason to use such low tolerance capacitors. Is there another reason behind it or did i miss something?

@proficnc
There are a couple that are needed, but not many, I think we need to do an overall review before the next build. I am doing a 1.6 at the moment, and will be reviewing everything. But as far as I can tell, all is functional now.
anything to do with the IMU CP should be, and also reg out on the IMUs

I was thinking about putting the first UBLed in the string on the board, as I have removed the Toshiba... Toughts? Also, do we need both the crypto and eeprom? We have FRAM.... And EMMC and SD card.... If we actually setup the OTP on the crypto so we can form a COA for bug and board tracking, I would like that, but let's keep the method public and simple, just the keys to be private....

The current three LEDs in the PXF are good enough for notifications when arming and so on. I doubt that an RGB LED in the autopilot would make a big difference when flying. I'd prefer the UBled configuration that the Iris+ has with a LED at the bottom on each leg.
The Crypto EEPROM has proved to be useful and quite easy to interface. I agree about the bug and board tracking. We should schedule a call to decide on these matters

@proficnc
Sounds good!

Hello, guys! Has anyone already used the new feature in LinuxSPIDriver that handles chip selecting in the kernel?
Víctor Mayoral Vilches
@vmayoral
@proficnc could you confirm that I2C is working in the board that we sent (v1.4)?
Philip
@proficnc
I havnt tested it yet, but will do
Víctor Mayoral Vilches
@vmayoral
thanks

@vmayoral
@proficnc, @imuguruza created v1.6 that includes an extension in some footprints (we've had issues with bad SMD mounting on some ICs). Might be useful to include it upstream.
Philip
@proficnc
Careful with that, there are many cases where extending footprints can actually make it worse... Which footprints?

@imuguruza
U303
looks the layout is not enough to mount the IC properly
also LSM9D and MPU9250

@vmayoral
@proficnc I'd like to set up up a call to discuss the authentication and board verification matters. Do you think it can happen next week?
Philip
@proficnc
Sounds good, if we can align this with the current Pixhawk COA methods, that would be great!. Ping me on Monday :)
Víctor Mayoral Vilches
@vmayoral
@proficnc will do!

Great talk tridge!! :smile:

@adeptastic
That is definitely a great talk! How is the quad core odroid working?
Andrew Tridgell
@tridge
@adeptastic I haven't received the Odroid-C1 yet - I got a shipping notice, so should be here soon
Philip
@proficnc
That talk was great! great job Tridge!

@vmayoral
superb @tridge!

@vmayoral I was showing some people at LCA the Erle Robotics site, and I couldn't find a howto page on how to take a BBB and get all the needed bits installed on it. Is there a page I missed?
Víctor Mayoral Vilches
@vmayoral
@tridge it is explained in our gitbooks
Andrew Tridgell
@tridge
@vmayoral ok, maybe a more obvious link would be helpful then?
Víctor Mayoral Vilches
@vmayoral
You can access them in the "Learn" section. I'd be happy to put it somewhere more obvious. A link should do it for now, sure
Thanks for letting me know. Will do it tomorrow morning first thing

@tridge just added a section under "Learn", that's the process we are using and it link to our images that flash the eMMC automatically
there's also a manual process described in a subsection. We keep putting time into the docs so feel free to add any comments and we will address them as soon as we can

For the Linux boards to take-off don't we need to make the firmware updates from the mission planner work?
I think if you can tell people, "upload the firmware just like you do for an APM2 or Pixhawk" then you'll get much better adoption of the board

@proficnc have you noticed that P8_17 layout? Shouldn't we remove the trace if it's marked as "spare"?
Víctor Mayoral Vilches
@vmayoral
@rmackay9 I like the idea of updating the boards from the GCS. We generally use Linux/Mac OS. Mission Planner seems to be Windows oriented, shall we look at APM Planner better or maybe QGroundControl?
@bugobliterator is looking into a web-based GCS, it'll be awesome to do it from there as well
Philip
@proficnc
On the latest from me, the trace is removed...
i use mission planner, and so do a lot of people...
Bill Bonney
@billbonney
APM Planner 2.0 will work better tha QGC for APM code.
QGC removed support for the APM stack in the latest code, and really focuses on PX4 Flght Stack
Philip
@proficnc
Really? Wow, didn't know that!
