Re: [beagleboard] Re: Ubuntu kernel source code for beaglebone black

[Devendra Gupta]

Thanks For the prompt reply Robert. I completely understand your point, But 
this is not the case with ubuntu source code, the uncompressed version 
takes around 600MB see below. Why the source code for Beaglebone black is 
too large, Does it mean that the source i am getting is the main tree and 
needs to be configured according to the Beaglebone config file. 


 Thanks

Re: [beagleboard] usb serial gadget

I see, and is there a way to bridge it to another serial at a low OS
level, without having to write a program that would do it manually
for it?

[beagleboard] Re: How do I get my Aptina camera (mt9m114) to work in kernel 3.14?

[byc013]

Hello Sergi,

I'm using the same on imx.6 linux 3.14.28 kernel and would like to 
integrate the mt9m114 sensor.
Have you managed to write a suitable driver?

The debate I have currently is whether to register the sensor as 'v4l2 
subdev' or 'v4l2 int-device'.

I'll appreciate your help.

Thanks
Yechiel

[beagleboard] Debian 4.1.15-ti-r40 on BBB with LCD touch cursor jumping to right.

[steovep]

Hi All,

I'm currently working on a small project which uses an LCD Cape 
(http://www.4dsystems.com.au/product/4DCAPE_43/) with a BBB Rev C running 
the latest version of Debian 4.1.15-ti-r40. Everything is going very well 
with development, with successful MODBUS comms to a Varible speed drive 
through UART4, grabbing RTC and analoge data over BB-SPIDEV0, as well as 
general IO by way of 24VDC in and relay outputs. This is all programmed 
using QT creator running on a cross development platform, which I'm slowly 
getting the hang of.

I must thank Robert C Nelson for all the hard work and long hours he puts 
into supporting new Kernels for the BBB. which makes this possible.

My only problem now is the touch screen, which for some reason, will make 
the cursor jump to the right a random distance when removing the pressure 
from the screen surface, (interesting as to why it is always to the 
right??) during the initial touch and even while dragging the cursor 
follows the stylus or finger perfectly, but as the stylus/finger is 
removed, the analogue touch sensors seem to throw one last erroneous X, Y 
coordinate. As can be seen if I run the TSLIB TS_calibrate program, and 
look at the console data streaming back

A few observations, 
Previous to loading Debian 4.1.15 the LCD touch screen worked perfectly on 
kernel ver 3.8, however I made the decision to upgrade as I had all sorts 
of problems trying to automatically load DTO's at startup. (mostly my 
custom DTO) so the hardware is fine.

The problem is no where near as bad when running the TS_calibrate program 
which happens about 50% of the time, as to when running the QT developed 
application, where it will happen 90% of the time.

Even through I believe QT writes directly to the frame buffer (using -qws) 
this problem can also be seen when running startx from the console.

>From my understanding the display uses a ti_am335x_tsc and there are 
snippets of forum comments that a problem is present - seems to have been 
an "on and off" issue over a number of years. However I cannot find a 
definitive solution to apply to my problem.

One option I have considered is changing back to 3.XX if I can sort out 
loading DTO's from boot???


Any help will be greatly appreciated, I'm losing hair over this one!! 

Thanks 

Steve

[beagleboard] usb serial gadget

[bremenpl]

Hello there,
The bbb image normally comes with usb gadget that simulates ethernet and mass 
storage. I have 2 questions regarding that:

Can the usb additionally simulate serial port? So on the host side one would 
see a com port (if windows) and on the beagle side it would be a tty interface? 
If yes, how to enable it?

Second question, can serial interfaces in linux be bridged together easily? For 
example, by connecting the beagle to the pc and writing to the usb serial 
gadget from the pc, i would like uart5 to send that data. In short terms, can 
beagle be configured to be a serial uab converter?

I would apreciate all help!

Re: [beagleboard] Docker for debian Wheezy

[Abhishek G]

Got it!!

Instead of "docker run -it debian /bin/bash", which is for 64bit intel 
processor, we have to "docker run -it armhf/debian /bin/bash" and it 
works!!!
It was a silly mistake and it took time to figure out.

Thanks for all the support till now :)
