How to monitor memory usage, booting time and temperatur​e on gumstix overo fire?

Hello.
I'm doing some project about performance evaluation of gumstix so i dont know how to start showing memory usage, booting time and temperature in number.
If anyone can help me about some information please help me.

Thank you

Setting mt9v032 driver parameters with 3.5 kernel

Hi Everyone,

Trying to set parameters on Caspa Camera as it's explaned in the wiki.
Explanations are given for 2.6 kernel though.
I'm on a 3.5.7-custom kernel and using the mt9v032 driver.

When I try to rmmod and then insmod the driver with parameters it gives the following error.

insmod /lib/modules/3.5.7-custom/kernel/drivers/media/video/mt9v032.ko auto_exp=0 auto_gain=0 low_light=1
insmod: ERROR: could not insert module /lib/modules/3.5.7-custom/kernel/drivers/media/video/mt9v032.ko: Unknown symbol in module

dmesg | tail
mt9v032:Unknown parameter `auto_exp'

How can I set the driver parameters in 3.5 kernel?

Thanks,

Tarik

Duovero AP doesnt forward http traffic

I set up an access point on the duovero to share my 4G Telstra 
connection for internet access.
I'm a newbie at iptables so I just tried out the nat script on the 
ubuntu site https://help.ubuntu.com/community/Router under "4.5. Enable 
IP forwarding and Masquerading".
This works fine for the 4G connection. But if I replace the 4G dongle 
with an ethernet wired connection to the internet, it forwards all 
traffic except for http.
In another test, I connected a laptop (running ubuntu) via ethernet 
switch to the access point and ran a netcat listener on the laptop. 
Wireless clients could ping and connect to the laptop on ports (22, 23, 
8080) but not on http port 80. Any idea how to diagnose what went wrong?
Thanks
Trupti

Performance counters on Overo and/or Duovero

Hi,

I've got a problem compiling the perf tool on both my Overo Water and Duovero Crystal.
For the moment, I use Yocto to build the system.

When I try to build the image with the profiling tools, I get this message :

ERROR: QA Issue: perf: The compile log indicates that host include and/or library paths were used.
         Please check the log '{$WORKDIR}/build/tmp/work/duovero-poky-linux-gnueabi/perf/1.0-r9/temp/log.do_compile' for more information.

And the last lines of the do_compile log are :

DEBUG: Shell function do_compile finished

I am quite new to the Yocto/BitBake compilation system and I don't really know what to configure to solve these warnings.
I managed to compile perf directly on the boards but all the hardware events are marked <not provided>. I doubt the kernel is not compiled with the support of these events and I didn't manage to compile the kernel with this feature.

So I have two questions :

First of all, is it possible to compile the perf tool for these boards (Overo Water and Duovero Crystal) from Yocto ?
And if it is possible, does these boards provide the ability to log hardware events such as cache misses (I know some CPUs only have a few registers and cannot provide these informations) ?

Nicolas.

wifi drivers for new overo air-p?

Subject: wifi drivers for new overo air-p?
Just got the new Air-p to evaluate as a replacement for the AirSTORM.

Unsurprisingly, I get this error on boot with my existing image that works on the airstorm...  
Anybody know where to get the mrvl/sd8787_uapsta.bin file, and any other needed files (and where to put it
so it is found?)

Overo USB (hub 1-0:1.0) enumerate error messages generated without apparent cause

Hi all,

I have an Overo Earth with Tobi connected to an externally powered USB
camera using the OTG port. The system works fine (even after the event I'm
about to describe).

Several days ago, my terminal (connected to Overo using the Console port)
started to show this message repeatedly:

There was no apparent cause for the message to appear: no hardware issue I
was aware of, no change in system configuration... I was just using the
Overo system to develop my application and to carry out tests. But even no
problem at all with the USB camera and my application, which is able to
access the webcam and works fine.

The message seems to refer to the HOST USB port (correct me if I'm wrong: I
have assumed this from the dmesg log below), which I have never used: when
the problem started there was nothing connected to that port. As stated
before, my only USB device is a webcam camera with external power. The
messages regarding the webcam detection and loading show no problem and no
noticeable difference from webcam related messages before this problem
started (I'm not reporting these messages here to keep the post within a
reasonable extension; if required, let me know).

The problematic messages appear in dmesg as soon as the EHCI driver is
loaded, the usb1 bus is registered and the OMAP-EHCI Host Controller is
found and added as 1-0:1.0. Everything seems ok in the messages related to
this initialization:

After this, some additional messages related to the OTG USB port and other
devices initialization appear. But then, just several milliseconds later,
the following messages start to appear repeatedly, intermixed with other
startup messages:

This set of messages go on coming out forever. The system starts up without
problem (appart from the cluttering of my terminal, which I stop by calling
dmesg -n 1), but the messages go on for a long while. Sometimes, they stop
with the following:

I don't know if this (usb1 is autosuspended and messages stop) happens
always or not. I do know that in several tests I have seen dmesg timestamps
of 1500 or higher, while in other tests (like the one reported above) the
suspension kicks in before.

My system kernel:

I'm not an expert on Linux or Overo at all, and thus I could be overseeing
something important. I have read on other posts that some kernel versions
had problems similar to this.

Does anyone have any hint on the possible cause of this?

Also, as my system seems to be working, is it safe to just remove the
offending messages from the terminal and use the board? Is it possible to
somehow disable the unused HOST USB port to avoid this?

And, by the way, what device does the message refer to? What is the
offending device that cannot be enumerated?

Thank you so much in advance,

David

Thank you! I can lower MPU rate now!

Beside saving power by lowering MPU rate, I wish to physically make useless
components sleep (like graphic card, voice card etc.)  via Power Management.
Thus, power consumption could be further reduced. I want to do this because
in my application, I hope Gumstix with independent power source can work for
a long period.

1. Poky Linux or Angstorm Linux contains such a Power Management Module?
2. Does a Linux Kernel Version contain such Power Management Module?
3. I found there is a TI OMAP patch might be useful. Is there any patch like
OMAP that can apply to Poky Linux?(Which is the default image I compiled by
Yocto.)

[Overo] Smart upgrade sees invalid SHA for certain packages

Any known issues with the repos or these specific packages?

Thank you! I can lower MPU rate now!

Beside saving power by lowering MPU rate, I wish to physically make useless
components sleep (like graphic card, voice card etc.)  via Power Management.
Thus, power consumption could be further reduced. I want to do this because
in my application, I hope Gumstix with independent power source can work for
a long period.

1. Poky Linux or Angstorm Linux contains such a Power Management Module?
2. Does a Linux Kernel Version contain such Power Management Module?
3. I found there is a TI OMAP patch might be useful. Is there any patch like
OMAP that can apply to Poky Linux?(Which is the default image I compiled by
Yocto.)

Gumstix Caspa with Yocto and OpenCV

Hi,

Gumstix Caspa camera (mt9v032) works well with the stock Gumstix yocto image using the mediactl commands.

However, when I want to get an image with OpenCV, it seems the /dev/video device won't be accepted.
Yocto uses 3.5.7 kernel by default right now.
Do I need to do some fine tuning to make the Caspa camera work with OpenCV?

Tarik
