Re: Aerocore firmware installation

Hi,

Sorry you're having problems and sorry for the late response.  The issue
with my response time is because you're not subscribed to the mailing list. 
Once subscribed, your post will get emailed out and you should get a
response back much quicker.  Please subscribe to the list.

To help be diagnose your issue, could you please tell me what AeroCore
you're using (what's the PCB9....XXXvYY)?

Where are you getting your firmware from?  What instructions are you
following?  Please be as specific as possible because there are different
instructions for different hardware versions.

Thanks,

Andrew

Re: Aerocore2 Duovero Setup

Hi,

Thanks for the question and I apologize for the lateness of my response but
because you aren't subscribed to the mailing list, I was alerted to your
question until I was browsing the forum while responding to another
question.  Please subscribe to the list so that your questions are emailed
out.

Here <http://media.gumstix.com/docs/brd30024.pdf>   is a link to the
AeroCore 2 manual which has updated instructions on how to setup the
software.  I would recommend downloading and installing pre-compiled images
first rather than compiling your own.  Get used to the system first, verify
functionality and then look into modifying software (if that's required).

As for voltage input, the AeroCore 2 can accept an input voltage of 5.5V to
36V.  It is outfitted with a common 2S LiPo balance connector (JST XH) so
that you can directly plug in a battery.  I've flown this on a quad using a
4S, I made a cable from a female 4S balance to male 2S so that I could
connect the battery directly to the AeroCore.  Please let me know where you
saw the 5.5V to 10V limit and I will update.

Thanks,

Andrew

Re: Advice Needed: ROBOVERO + OVERO COM + 2 USB CAMERAS

Hi,

Welcome to the Gumstix community.  I apologize for not responding to this
earlier but since you're not a subscriber to the mailing list this question
wasn't emailed out.  Please subscribe to the mailing list so that everyone
is made aware of your questions and can respond promptly.

Getting back to your question, stereo cameras on a UAV.  Is there a reason
why you're not considering the AeroCore?  Using a USB hub attached to the
single USB host port I was able to connect two USB cameras without a
problem.  The OpenCV libraries can be compiled into a yocto image or the
package installed into a current version (using smart installer).  I would
highly recommend the AeroCore over the RoboVero due to the AeroCore's
support of the PX4 and MissionPlanner (APM) software.

Please let me know if you have any questions.

Andrew

gpio dts question

I have some pins I want to mux as gpio for use with sysfs in userland

For example

&am33xx {

        avr_pins: avr_pins {
                pinctrl-single,pis = <
                        0x09c (PIN_OUTPUT | MUX_MODE7)          /* P8.9,
led_green */
                        0x034 (PIN_OUTPUT | MUX_MODE7)          /* P8.11,
led_red */
                        0x03c (PIN_OUTPUT | MUX_MODE7)          /* P8.15,

                        0x02c (PIN_OUTPUT | MUX_MODE7)          /* P8.17,

Now how do I finish the definition so I the pinmux takes effect?

Use SD card as secondary memory

Hi all,

I manage to flash my gumstix via NAND, but now I would like to know if it is
possible to use the empty slot of the SD card with an secondary memory
source, use the SD card as a external drive. Can I do that?

GPIO 168 problem

I am trying to use GPIO 168 in my Gumstix Overo AirSTORM-Y COM (I want to be able to reset the usb device pluged) but I can't see it in /sys/class/gpio
I try to create it but it doesn't allow me:
root <at> ssanchez-GT150-F1:/sys/class/gpio# echo 168 > export
-bash: echo: write error: Device or resource busy
root <at> ssanchez-GT150-F1:/sys/class/gpio#

I try to compile a new u-boot using the next commands but It has the same result:
git clone git://github.com/gumstix/u-boot.git
cd u-boot
git checkout v2015.04
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- omap3_overo_config
# Now I edit the .config file and change CONFIG_DEFAULT_DEVICE_TREE="" to CONFIG_DEFAULT_DEVICE_TREE="omap3-overo-storm-tobi"
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- all

Can you help me?
Thanks!!!!

ironstorm-y rated for -25oC anyone used it successfully for -40oC ?

Hello,

I want to install an un heated overo ironstorm-y outside.  The minimum temperature reached where I want to place it is -30oC.

Anyone has seen the device working successfully in these condition ?

Thank you

Write to flash

Hi,
I was able to build the UBI image of my rootfs, but when I try to flash it (using the gumstix tutorial http://gumstix.org/how-to/70-writing-images-to-flash.html) the command "load" does not work, it says that it is an unknown command. Is there an aternate command?

Badly soldered SMSC-LAN9221 on TOBI - FAO Gumstix employees

Hi guys,

My production manager sent an email through to a Joel Skaliotis at support <at> gumstix.com regarding an issue we've been experiencing with the TOBI board. The SMSC-LAN9221 IC is not soldered appropriately and fails out of the box on a number of our boards.

On other boards, with similarly bad solder, the IC will fail unpredictably in the field, which is a real nightmare for us. It should be noted that we can 'fix' the IC with careful reheating of the solder, but it requires an exceedingly steady hand and is not something most people could do in the field.

Joel has not responded to my production manager (Mr Dan Darling) since his original comment that he would alert the CEO and pursue things with the manufacturer. That was on August 14th. Our case number is 9421 as far as I know.

Apparently when we telephone gumstix support, we get a message about the google voice number being disconnected.

If someone could please chase this up and give us an idea of what, if anything, is going to be done, that would be appreciated.

You can contact our production department via Mr Dan Darling at the following address: dannyd <at> aq1systems.com

Regards,

Akram Hameed

UBI image of rootfs

Hi,
I'm having trouble in the process of creating an ubi image of my rootfs to boot without the SD card. I'm made some modifications to the rootfs that was generated on bitbake. When I use the command sudo mkfs.ubifs -r /media/user/rootfs/ -m 2048 -e 126KiB -c 2313 /home/user/Documents/ubifs.img, the file created (ubifs.img) appears to be empty, at least is what I get when I run the command sudo ubinize -vv -o ubifs.img -m 2048 -p 128KiB image.cfg. Am I doing something wrong? If so, what could I do to make it work?
