Console port on Tobi expansion board not working - USB Hardware ID Unknown

It seems that the serial to USB converter on my Tobi expansion board
does not work. It appears in Windows as Unknown device, it was
confirmed on two different Windows machines.

When I go in Device Manager on Windows to Properties->Hardware Ids, it
says UNKNOWN. Also, when I use Microsoft USBView, it says
DeviceFailedEnumeration. Is this normal?

I installed the drivers from http://www.ftdichip.com/Drivers/VCP.htm
but it did not help. The converter is either defective or the lack of
those usb ids prevents the drivers from installing properly.

Does it look like defective hardware or am I missing something?

Thanks,

Tom

Need to switch Overo from Ubuntu to Yocto to allow use of Caspa and not sure how best to proceed

Hi have an Overo Firestorm-P board that I set up with Ubuntu a few 
months ago. Then, the project got put on hold. Now, it is back. But, I 
was never able to get the Caspa camera to work using Ubuntu, which is 
what is on my desktop. I see where Yocto apparently supports the Caspa 
camera, so I need to scrub Ubuntu from my Overo and install Yocto 3.5 
(?) to the flash memory card. The card is large, so there will be no 
problem with room, although I don't want to have to spend a huge amount 
of time trying to build and deploy an image over the net if I can avoid it.

I downloaded Linux-Omap_3.5.zip but now I am not sure how to proceed. I 
believe that is the whole image that I need, although it is only about 
125 MB in the zip file. I am not sure if I can go directly from the zip 
file that I downloaded, or if I need to start with the MLO, RootFS, Das 
U-Boot, and uimage and then after creating a micro-SD card with them, 
then going to the zip file that I downloaded. And, if that is the case, 
I am still not sure what the procedure is. I assume if I have to start 
with the MLO and other files, that the makefile folder (or other folder 
in the download) will do all that I need.

It has been a while since I used the Gumstix boards.

Thanks in advance,
Ed

Enabling Ethernet over USB

Hi everyone,

 

I would like to enable Ethernet over USB on the Overo AirSTORM-P using the Gumstix console image.

 

I found the wiki entry (https://github.com/gumstix/Gumstix-YoctoProject-Repo/wiki#using-usb-otg-port-as-ethernet), but when I try to load the network gadget driver with

 

modprobe g_ether

 

It prompts

 

modprobe: FATAL: Module g_ether not found

 

How can I load the module?

 

Michael

Flashing Overo NAND yocto 1.7

Greetings,

I've just built Overo images using the new 1.7 repo.  Although the mtd-utilities are installed and the mtd drivers are enabled in the kernel, there seems to be no binding to the NAND devices in the device tree.  Is this an omission, not supported, must be patched, or ???

Thanks,

Bruce Harrington

Re: u-boot duovero

Not sure if you figured this out yet.
If I were you I would just add a new patch to u-boot instead of modifying
the existing patch.

Here are some brief instructions.

# first build uboot with bitbake

bitbake virtual/bootloader

# cd to the TMPDIR directory where it built
# the path will be different based on your version of Yocto, local.conf
# and u-boot version, but you can figure that out
# for this example

cd (TMPDIR)/work/duovero-poky-linux-gnueabi/u-boot/2014.10-r0/git

# This is a git repo, so first make sure all patches that were already
# applied by bitbake are committed. They should be.

git status

# if there are any uncommitted changes, commit them now
# the commit message doesn't matter. This is all getting wiped
# on next build.

git commit -a -m 'scrap'

# cd to the duovero mux header directory

cd board/gumstix/duovero

# edit the duovero_mux_data.h file

# I did a trivial mux change, making the one-wire pad a gpio

No header files installed by OpenCV packages from the repository

Hello,

I wanted to install OpenCV libraries from the Gumstix repository.

When I tried installing the main package (smart install opencv) only
2.6kB of data was downloaded and I did not see any new files at all,
or at least, find / -name "*opencv*", did not find anything.

Next, I tried installing individual libraries (smart install
libopencv-imgproc2.4). This time, the library files (.so) were
installed, but what is still missing are the header files.

Is there something wrong with these packages or am I missing something?

Thanks,

Tom

Changes to Overo FE Flash/RAM Specification? (Detecting 1GB Flash)

Hi everyone,
We have just received a fresh batch of FE COMs from Gumstix, and have run
into a problem.
The COMs which have just been delivered are fitted with Memory Chips which
have manufacturer code 0x2c (Micron), and ID of 0xb3 (1GB Flash, 512MB DDR).

Unfortunately, the (old) X-Loader 1.5.2 we are using does not support this
memory, and so the system hangs when we attempt to install our production
firmware.

My question is two-fold:
1)  Was this memory an intentional upgrade by Gumstix?  If so, it would have
been helpful if Gumstix could have at least put a product change notice on
their website or - better still - sent us an email warning us that the
latest batch of gumstix boards we have ordered are significantly different
to all the ones which have been shipped previously.  At time of writing, I
cannot find any mention of FE COMs with this memory configuration anywhere
on the Gumstix website.

2)  Assuming that the change is intentional and the boards should work OK...
can anyone direct me to a git repo where patches for X-Loader (and u-boot,
if necessary) can be found?  Unfortunately, we really need to continue using
the old seperate X-Loader and u-boot, rather than the SPL bootloader, to
minimise code changes and disruption to a mature product.

Thanks in advance,
Chris Cotton.

Radiation Tolerance of Overo COMs

Hello all,

I was wandering about the radiation tolerance of different Overo COMs. Is there any reason to believe that the Overo IronStorm-P is any more or less radiation tolerant than the Overo Fire or the Overo FireStorm-P?

I did see this post by Bill in the mailing list archive http://sourceforge.net/p/gumstix/mailman/message/16996104/. Although very informative, it doesn't really answer my question as to which COMs are more or less susceptible to the different failures caused by radiation.

Caspa image on 3.5.7 vs 2.6.34

Hi to all,
I'm using the Caspa camera with Gumstix Overo.

I'm able to capture an image as well as streaming video, but there is a
strange difference in the produced images when the process is performed
with kernel 2.6.34 related to that with kernel 3.5.7

To be more specific: using the same Caspa module, the same Overo
module (a Overo Water, in my case), images captured when the pipeline
runs under kernel 3.5.7 have a yellow tint while the same images
captured under kernel 2.6.34 don't have this tint.

Anyone know something about this strage difference?

I'm interested in using the kernel 3.5.7 (because the gstreamer
pipeline I need work with the yocto generated system, thus kernel
3.5.7, but not under 2.6.34 -- to be more specific, the pipeline runs,
but the generated files are not playable under 2.6.34), thus I need to
solve this problem and obtain neutral images.

Thanks to all
Francesco

PS: what I mean with "same" above I mean "phisically equal"

AirSTORM-P COM - wifi not working properly

Overo AirStorm-p comes with new wifi chip W2WCB0015 which uses different names for wifi devices.

root <at> overo:~$  iwconfig
mlan0     IEEE 802.11abgn  ESSID:off/any 
          Mode:Managed  Access Point: Not-Associated  
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:on
         
lo        no wireless extensions.

uap0      IEEE 802.11abgn  Mode:Master 
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:on
         
eth0      no wireless extensions.


It is not wlan0 but mlan0, similar as it is on Duovero. We tried to rename it in wpa_supplicant.conf and interfaces, but still we could not connect to any AP. We got same results with downloaded image and compiled image.

Should we change wlan->mlan0 in some *.bb meta settings before build ? Do we need to patch kernel ?

AeroCore2

Hi I'm new here and I'm looking for informations about the AeroCore 2 from
gumstics which should be compatible with px4 as I read on their website
https://store.gumstix.com/index.php/products/647/
The user manual http://gumstix.org/images/pdfs/aerocore_2_manual.pdf is not
readable
This Documentation looks also a little bit strange
https://geppetto-data.s3.amazonaws.com/designs/schematics/e971ef1e-906b-11e4-8856-0a483ac2087e.pdf

Does anybody work whit this device?

Sounds nice to have an Linux driven controller and the px4 on the same board
but It seems like there is no useful documentation...
