WaterSTORM//Summit on arducopter

I am doing a project out of self-interest. It is mounting the
WaterSTORM//Summit on my arducopter (APM 2.5) to act as an on-board
processor for high-level control and image processing.

There is a few burning questions which I would like to hear some opinions
about before I start hacking my components.

As it is a mobile robot, I would need to power Summit using the LiPo battery
that is already on the quadrotor. The quadrotor has a power module which
provides 2.25A at 5.37V. This power module is capable of powering up the APM
2.5 controller, RC receiver, Xbee and Mediatek GPS. Looking at the values
and the schematic of Summit, am I right to assume that this is enough to
power up the WaterSTORM//Summit as well as the other components?

Arduino Mega 256 (which APM 2.5 is based on) has a 5V pin which can supply
the stated voltage to any peripherals that require it. Can the
WaterSTORM//Summit be powered up by that?

Qemu

Has anyone used qemu to emulate the hardware surrounding the Overo? I've seen some mentions of it in the yocto repo, scripts and the like, but I'm curious what the level of effort might be to make it useful.

Thanks,

Overo as Access Point

Hi,

I would like to turn on the wifi access point feature on the overo. But most of the article I have looked online is for the kernel 2.6. I am currently using kernel 3.5.7. Is anyone have any luck on turning on the wifi access point on the kernel 3.5.7?

Regards,
ABM

Problems with next-wip

Guys:

I'm trying to build with meta-gumstix-extras' next-wip branch as of
the date of this email, and I'm stuck here:

...
ERROR: No recipes available for:
  /home/bgat/gumstix/yocto/poky/meta-gumstix-extras/recipes-bsp/powervr-drivers/omap3-sgx-modules_5.01.01.01.bbappend
  /home/bgat/gumstix/yocto/poky/meta-gumstix-extras/recipes-graphics/libgles/libgles-omap3_5.01.01.01.bbappend

Per the README, I've checked out poky.git:master-next,
meta-openembedded.git:master-next, meta-gumstix.git:next,
meta-ros.git:master, and meta-ti.git:master.

I'm not an expert in Yocto, but I've built a few kernels in my day.
My objective is to get an Overo kernel that boots with Device Tree, so
that I can merge a driver that wasn't written to use platform data
structures.  (Yes, I could add platform data but I'm trying to
modernize the whole system.)  I really don't need the rest of the
Yocto environment, because my target device is running Debian.

Can anyone point out what I'm doing wrong?  Or tell me where the FM is
that I need to R?  :-)

Thanks!

b.g.

SDCard setup for installing ANDROID on pepper

I downloaded the image files from https://www.gumstix.com/software/software-downloads/?selection=eyJzb2Z0d2FyZSI6ImFuZHJvaWQiLCJidWlsZCI6ImZhY3RvcnkiLCJoYXJkd2FyZSI6InBlcHBlciJ9 

however I am not sure how to get android to install on the gumstix pepper board ...
I extracted them to the SDCard

SDCARD FileStructure (ext3 FS)
/boot/
     MLO,uImage,u-boot.img,uInitrd
/system/
      (extracted contents of system.tar.bz)

I am not sure what I am supposed to do with userdata.tar.bz2

I connect up to the uart (FTDI) bootloader thing ... and connect the power and it seems like it tries to install android 

but it fails and exits with 

"Kernel Panic: No init found try using init= option to kernel"

I have no idea what this means or how to fix it .... hopefully someone here knows how to get the image that gumstix provides to install ...  (as far as I could find there is no readme or anything that explains where to put the files)

basically i was looking for a you have the tarball of the image here is a step by step to put it on the SD card and how to install it 


(I have installed android images for rowboat-froyo on other devices ... but the file structure seems very different ...)

Rebuild glibc with debug information

Hi all,

I've been trying to do this for a long time, but no success to date. I'm
trying to use Valgrind in my already deployed Overo system. I was able to
cross-compile Valgrind from source and install it in Overo, but the system
libraries were stripped when building the Overo image for the first time,
and Valgrind complains about missing symbols required for redirecting memory
management functions.

Rebuilding the whole image is not currently an option, so I am trying to
just rebuild the required libraries unstripped and install them in Overo
with opkg.

However, I'm a total newbie in this area. I would be grateful if someone
gives me guidance with this.

What I have done so far, using information found in other posts of this
list, is changing the local.conf file to disable binary stripping and to
include debug information, as follows:

I've being able to recompile a single package:

but this does not seem to generate a new or updated ipkg in my working dir.

I did also try to regenerate the whole image, thinking this would result in
ipkg generation. The modifications in local-conf seemed to work, as the
generated image is now much bigger (which is what I expected, as it is
including debug information now), but no new ipkg was generated: all files
in my deploy/ipkg folder have the modification date of my first standard
image.

I'm not sure this is what I should be doing to get Valgrind working, but
even if it is not, I need to be able first to generate and install rebuilt
ipkgs.

What steps should I follow to get the ipkg generated?

I guess resetting everything (removing the tmp directory completely) is the
safest way to go, but... is there a faster way? My development machine is
not fast, and a complete image generation takes many hours.

Thanks in advance,

David

Yocto gcc

Hey,

I am using the Yocto console image and I am trying to compile a program with
gcc. I am getting this error: 
gcc: error trying to exec 'as': execvp: No such file or directory. 
Is there a package that I still in need to install? 
I have tried what the gumstix website said but it doesn't work.
smart install packagegroup-core-sdk

Any help would be grateful.

Thanks,

IPV6 Unknown symbol with stripped down kernel

I made a sort of heavy handed attempt to strip all the networking modules out of the kernel. It seems in doing so I've either removed something necessary or failed to remove everything because after entering linux I get a slew of messages about ipv6 failures:

Welcome to Linux!

[    3.791351] ipv6: Unknown symbol inet_recvmsg (err 0)
[    3.796874] ipv6: disagrees about version of symbol single_release_net
[    3.803802] ipv6: Unknown symbol single_release_net (err -22)
[    3.809906] ipv6: disagrees about version of symbol skb_free_datagram

There's more, but they're all pretty similar, various unknown symbols causing error codes 0 and -22. I think this would normally be the point where I'd see a message about NET registering protocol family 10. I think I removed anything in the kernel .config regarding NET modules.

Is there a network related module that's required that I need to add back in or is there a start up script I need to remove (I removed all the network related systemd scripts in rc5.d and rc3.d).

Have I gone too far or just not far enough (and where should I look next)? My guess is if it's still trying to run something related to IPV6 and a network device then there's still more to be removed.

Thanks,

Overo COM - Newby Q's

Hello List,
I am a complete noob to Yocto so apologies in advance if I'm missing something that's obvious.
I have a Gumstix Air COM and a Toby board that I need to get running with Strongswan IPSEC.
I have read the Quick Start Guide at https://www.yoctoproject.org/docs/current/yocto-project-qs/yocto-project-qs.html
I have managed to setup the poky Build system and have successfully built and tested the
gumstix-console-image using an SD card.
Anyway, the out-of-the-box Linux Kernel (3.5.7) isn't configured the way I need to to be.  I need to add the
IPSEC modules
that are described here: http://wiki.strongswan.org/projects/strongswan/wiki/KernelModules

I have been trawling through the Yocto Linux Kernel Development Manual (at http://www.yoctoproject.org/docs/1.6.1/kernel-dev/kernel-dev.html)
and I understand that I need to generate either a new config file and/or a defconfig with configuration
fragments.  How do I best do that
with the Gumstix?

I am also struggling with how the meta-gumstix layer builds the 3.5.7 kernel and where it ends up.  I can see
that in the meta-gumstix/recipes-kernel/linux/ folder
there are a number of bb files for linux-gumstix-3.14 to linux-gumstix-3.5.7 and that there is a files
folder with a defconfig in it.  How does yocto know to build the
3.5.7 version? Given that there's already a defconfig in the files folder how do I best modify that to
include the IPSEC modules I need?

Any help much appreciated as I have an awful lot to learn and no time to do so.
Regards,
Denzil
