Hi Mark, we just started using Gitter recently, and yes, it uses the GIT name, so it does hide people a bit! I am Philip Rowse, and am Hardware Owner/lead on PXF. I am also the Lead Systems Engineer at 3DR, working on all things next gen... Your question as to road map... Craig's answer covers it well, from an R&D point of view, the PXF is an exciting prospect, but if you want to have a reliable autopilot that is well tested, the Pixhawk is the way to go! PXF is not intended to be a product by itself, it is the stepping stone to what may exist in 2016.
There is a long way to go in getting the flight systems proven on a Linux computer, and future issues will come up, this platform allows us to find and deal with those issues in preparation for the next generation
@vmayoral especially Servos, I will be adding a power management system at some stage, (the module I am using for Pixhawk) that will help with this
I'd like to jump in to that bleeding edge but I also want to be in the air sooner is the reality I guess
You can judge it yourself checking this channel https://www.youtube.com/channel/UC4PSPiQ7aIvQGgNTdp9IqOg
If you want to just get flying, and play with Linux, this is a good step..... All the methods are transferable... In the future however, you will also be able to use ROS or MavLink
Speaking of which, i've got ROS working in the Edison. I am aware you guys are playing with it so i'll try catching up with Brandon about it.
I'd like to do some testing with the Odroid and Erle-Brain as well. @proficnc do you have experience with the different ODroid flavours? Is the U3 the best one as a "companion computer"
as far as the Edison, we have done quite a bit with it, and Brandon will be able to fill you in. Though Kevin is the expert on that topic
wow that is affordable... I was actually considering putting an x86 kinda SoC up on a big fixed wing :D I'm sure making the payload run on ARM would be worth it though and scale very affordably
@vmayoral, if you'd like an Odroid U3 (which is what I use) I'd be very happy to mail you one including a Wifi dongle that I know works with Linux. Just one favour I'd ask in return is that one of the first things you do with it is try setting up a Wifi access point on it that makes a directory on the Odroid available (probably using Samba) to a PC connecting to that access point.
This offers goes out to anyone else who would like an Odroid U3 by the way as well (I have more than 1)
http://www.hardkernel.com/main/products/prdt_info.php?g_code=G137447734369 is this compatible with what you want to use?
@proficnc https://mega.co.nz/#!aQ8FnB4B!CpqMmZdVyOWvryxdb9Hzvo2UnL44L-0JttPRswgC6Ek, should still be active but it does not include the latest changes in master so you should clone APM and compile it.
I plan to create a new image as soon as I finish debugging the Power Module support for the PXF (we are getting some weird voltages).

@rmackay9 procedure for wireless access point setup on odroid (half of what you're trying to get). http://forum.odroid.com/viewtopic.php?f=52&t=6282 After that I would usually use rsync/ssh2 to copy files but the samba approach is definitely more user friendly for most people. and I am really impressed that tridge offered to help you set samba up, I would also be willing if he is busy at the time.
@vmayoral is it possible to include some details on what you are expecting for test results on the youtube vids? It is hard to tell if it is just R/C free flying or fighting a lot of wind or what in some of the videos. And I missed your message earlier (before odroid mention), which is the reason I'm just looking now
like a mission planner picture in picture or something? Sorry, the production value of some of those RC hobby guys is actually REALLY high and you get spoiled, I would love to be doing my own testing in reality
i presume it should work as well with the ODroid since i compiled myself the kernel modules.
and it supports 802.11 ac. We are actually using the 5 GHz band. Quite useful when using RC controllers :)
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?
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 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
looks the layout is not enough to mount the IC properly
