Overo and Robovero not working

I have a robovero and an overo air-storm y board. The robovero works alright. 
I tried using recent ubuntu images for overo, but the boot process stops at
different stages every time and is withdrawing a high current of 1.6A. 
last time i ran the system it stopped at following line
U-boot SPL 2014.10 (Feb 25..)

Also, is there any yocto image (already built) available. or can i just copy
the rootfs and boot folder on a sdcard and expect it to run.

Kernel 3.18 for overo - no 720MHz support?

Hi guys,

Just tinkering with newer kernels and I note that kernel 3.18 complains about my requested mpurate argument of 720:

[    3.723968] cpufreq: __cpufreq_add_dev: CPU0: Running at unlisted freq: 720000 KHz
[    3.734191] cpufreq: __cpufreq_add_dev: CPU0: Unlisted initial frequency changed to: 600000 KHz

Anyone else experienced this? 

Bootloader reports correct max CPU MHz: 

U-Boot 2015.07 (Oct 15 2015 - 12:16:02 +1100)
 
OMAP3530-GP ES3.1.2, CPU-OPP2, L3-165MHz, Max CPU Clock 720 MHz

Cpufreq-info reckons the hardware will only scale to a lower OPP though:

root <at> overo:~# cpufreq-info 
cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009
Report errors and bugs to cpufreq <at> vger.kernel.org, please.
analyzing CPU 0:
  driver: cpufreq-dt
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency: 300 us.
  hardware limits: 125 MHz - 600 MHz
  available frequency steps: 125 MHz, 250 MHz, 500 MHz, 550 MHz, 600 MHz
  available cpufreq governors: userspace, performance
  current policy: frequency should be within 125 MHz and 600 MHz.
                  The governor "performance" may decide which speed to use
                  within this range.
  current CPU frequency is 600 MHz (asserted by call to hardware).
  cpufreq stats: 125 MHz:0.00%, 250 MHz:0.00%, 500 MHz:0.00%, 550 MHz:0.00%, 600 MHz:100.00%

Thoughts? Anyone else have this behaviour? I should note for the record I have reconfigured from the default kernel, I can attach the defconfig if you like.


Our company is considering moving to DM3730 overos anyway, but we have a fair few field units running the omap and it's nice to get a little more bang for buck if possible...

Cheers,

Akram

Aerocore2 UARTs crosstalking

Hi Everyone,

The problem is the following - when I use printf() function for debugging purposes it writes not only to Nuttx console but also to the "Cortex-M4 UART2". And I have no idea how to fix this.


Best regards,
Alex

Aerocore2 debugging problems

Hi Everyone,

Does anybody succeeded in outputting of a debug value (via "debug_key_value" topic) to QGroundControl?

This mechanism works on the 1st generation Aerocore, but unfortunately it doesn't work on 2nd generation Aerocore.

Besides, the printf() function sometimes doesn't output anything and I have to restart the target application (or daemon) and then it starts to work. May be somebody know how to fix this..


Best regards,
Alex

Equivalent sizes for Tobi coin cell battery

The Tobi coin cell battery is Panasonic part # ML-621S/ZTN. These are only available at a few places online and only Digikey seems to regularly have them in stock.

Is there an equivalent IEC or ANSI size designation for this battery (or perhaps a vendor-specific e.g. Energizer or Duracell equivalent), or is there a more commonly available battery size that is compatible with the slot on the Tobi?

While we order the ML-621S/ZTN's in bulk, it is sometimes the case that we need to obtain a battery in a last minute situation, and it would be nice to be able to run to the nearest Walgreens/CVS/etc. 

Our usage volume is approximately 20-30 Tobis and 50-60 Gumstix per year. We also have our own boards and will be adding a coin slot in future revisions, and it would be desirable to have a more easily obtainable battery size that can be shared with the Tobi.

Thanks,
Jason

Duovero WiFi errors (kernel 4.1)

We were having some reliability issues with WiFi (and other things) on kernel 3.17 and decided to move to kernel 4.1 as Scott Ellis did (http://www.jumpnowtek.com/gumstix-linux/Duovero-Access-Point.html). My system doesn't exhibit errors and seems stable enough but a collegue's Duovero system produces a set of WiFi related messages (appended below) every so often, dropping the WiFi (but 9/10 times reconnecting ok).

I can't reproduce this on my system - on her system, an older 3.17 release does not produce these messages and seems fine! It's a bit puzzling - are there different hardware revisions of the Gumstix Duovero out there using different WiFi chipsets? Has anyone else seen these messages?

Thanks,

Conor/

Poblems retrieving meta-gumstix-extras recipes from yocto

After including meta-gumstix-extras-fido layer from yocto hob application, after a while I receive the following error:

Any idea on how to remove the receipe checking for these packets, or how to fix it including them without error ?
Thank you.

smart package manager and kernel 3.17

I would need to install the kernel 3.17 into my gumstix overo.

As default, from the web page 

https://www.gumstix.com/software/software-downloads/

the rootfs image for yocto includes the kernel 3.17.8-custom.
But for people who need drivers as ftdi_sio, only the version 3.17 is
available, which does not work into 3.17.8-custom. insmod doesn't load
it..

I try to install the packages:

kernel-3.17-r0.88.overo.rpm			      	      
kernel-vmlinux-3.17-r0.88.overo.rpm

But I can't see any kernel image 3.17

Any idea of wherever it could be installed ? 

Thank you
Simon

Re: magic usb port

I can answer my own question – it’s a windows firewall thing.  If I open our Windows application with the Gumstix connected to USB hub #3 I get asked for connection confirmation, then everything is OK for more direct access via a browser.  I fired the app up so many months ago I had forgotten.  Windows hadn’t.

Subject: [Gumstix-users] magic usb port

 

I have inherited an application which runs Lighttpd Web Server on a Gumstix Overo WaterSTORM.  If I plug the OTG USB into the left-hand socket of my (powered) StarTech USB hub everything is fine with the given IP address (192.168.1.1) I can connect & see files that I expect to see.  Yet, if I plug the USB cable into any other socket (3 remaining sockets on StarTech hub, front or back sockets of Windows PC) I get:

“ERROR

The requested URL could not be retrieved

Connection to 192.168.1.1 failed.

The system returned: (61) Connection refused”

 

How is this possible? 

Is it a USB enumeration issue? Or USB speed issue?

What do I need to do so I can connect on any USB port, not just my magic No. 1?
