[beagleboard] Re: Is it possible to make work the BBB C program code without installing any operating systems?

[mike . maikaefer]

Check out StarterWare from TI (there is also a FreeStarterWare project 
available on sf.net which contains a lot of bugfixes and feature 
enhancements TI never managed to publish). It contains TCP/IP stack, USB 
stack, functions to read/write FatFS on SD-card and many things more - all 
as bare metal without the need to use an operating system and with a lot of 
useful examples.

Hi,

I am interested in use libpruio, and I would like to know if you were able 
to use it in that kernel version.
I will work with the ADC too, so maybe you can give some advice to install 
the libpruio and how to use it.

PD: I'm using this kernel version:  "Linux beaglebone 4.4.82-bone19 #1 Mon 
Aug 14 21:56:51 UTC 2017 armv7l GNU/Linux"

Re: [beagleboard] Cannot get audio over HDMI working

[adrien . courdavault]

I have the same exact problem with Linux beaglebone 4.9.45-ti-r57 #1 SMP 
PREEMPT Fri Aug 25 22:58:38 UTC 2017 armv7l and Linux beaglebone 
4.9.63-ti-r77

I have tried to update the OS, change the resolution, the audio is not 
working,

The other thing I confirm is that GPIO1.27 is LO it commands the oscillator 
of the audio I2S, which is in this case disbled.

I guess it s just software as I had it working once by accident (and i 
don't know why nor why it does not work anymore)

[beagleboard] Re: LIBPRUIO

[TJF]

Hi Jaime!

In one project I've libpruio-0.4 running on

 4.4.22-bone13

It should be possible to run it (version 0.4) on your kernel version as
well. But it's a mess to install on 4.x kernel versions (recompiling of
inertial device tree is necessary to get all PWM working). And I didn't
finish the docu yet.

So if you want a precompiled binary and complete docu, you'll have to
switch to a 3.8 kernel version with libpruio-0.2.

Otherwise, you can download and compile the libpruio-0.4 source here

  https://github.com/dtjf/libpruio

Regards.

Well, you only have the "TX" and "GND" pin connected on the debug usart..

Hook up the "RX" and then you can login...

[Louis Whitcomb]

To build ROS Kinetic from source on the Beaglebone, in addition booting 
from the SD card (for extra flash space) you need to create and enable a 
swap file. A 1GB swap file seems to wrok fine.  Without a swap file the 
build of ROS Kinetic failed due to lack memory.   Instructions here:

[beagleboard] Trouble building a configfs for HID device on BBBW

[sscirrus]

I am trying to get a BBBW to register itself as a pure HID device.

I'm starting with a modified version of Phil Polstra's bash script 
presented at DEF CON (attached). His script was built originally for 
Ubuntu, but I'm running the latest 9.1 Debian image.

I have updated the original last line from echoing 'musb-hdrc.0.auto' to 
'musb-hdrc.0' (for versions 4.9.x, which mine is).

Here's what happens:

*debian@beaglebone*:*~*$ sudo bash create-hid-BB.sh

create-hid-BB.sh: line 44: echo: write error: Device or resource busy
*debian@beaglebone*:*~*$ sudo bash create-hid-BB.sh

create-hid-BB.sh: line 29: echo: write error: Device or resource busy

create-hid-BB.sh: line 30: echo: write error: Device or resource busy

create-hid-BB.sh: line 31: echo: write error: Device or resource busy

cp: error writing 
'/sys/kernel/config/usb_gadget/kb/functions/hid.usb0/report_desc': Device 
or resource busy

ln: failed to create symbolic link 
'/sys/kernel/config/usb_gadget/kb/configs/c.1/hid.usb0': File exists

create-hid-BB.sh: line 44: echo: write error: Device or resource busy

*debian@beaglebone*:*~*$ sudo bash create-hid-BB.sh

create-hid-BB.sh: line 29: echo: write error: Device or resource busy

create-hid-BB.sh: line 30: echo: write error: Device or resource busy

create-hid-BB.sh: line 31: echo: write error: Device or resource busy

cp: error writing 
'/sys/kernel/config/usb_gadget/kb/functions/hid.usb0/report_desc': Device 
or resource busy

ln: failed to create symbolic link 
'/sys/kernel/config/usb_gadget/kb/configs/c.1/hid.usb0': File exists

create-hid-BB.sh: line 44: echo: write error: Device or resource busy

I also tried:

   1. Restarting the system.
   2. Leaving g_multi in place.
   3. Building a kb folder in another folder with the customizations 
   specified in the attached script.
   4. Copying the kb folder to /sys/kernel/config/usb_gadget/
   5. This also fails with the same messages. It's almost like the moment 
   there's a /sys/kernel/config/usb_gadget/kb folder, the system connects to 
   it and starts using it. (Note that during this time, my computer is NOT 
   registering the BBBW as a HID device yet).

It seems like it shouldn't be this difficult. How can I make a BBBW pure 
HID?

add the -ex options to bash, so you can actually watch and therefore
trace what happens..

Re: [beagleboard] Re: connmanctl

[Mala Dies]

Hello,

I get the connmanctl cmd on the terminal working w/ the BBBW w/out using 
those listed files. I only have to use services and then agent on. I type 
my password and it works.

Seth

P.S. I am not sure about the other fellow, though. I have not heard from 
him.

 Hey Again,

 I am using an image from 
 http://elinux.org/Beagleboard:BeagleBoneBlack_Debian. The flasher 
 image called Stretch is what I used. I did not need to type, and this is 
 after *sudo connmanctl* is entered in the prompt, *wifi enable* or *wifi 
 scan*.

 Seth

 P.S. Get back to me. I may be able to help you.

Re: [beagleboard] Unable to get WiFi working on BBBW using the latest Debian image

[William]

I have only a 5V TTL serial cable, used only for receiving debug messages 
on PC (I don't want to burn something connecting the TX and V since voltage 
is different).
For a normal SSH connection I use the mini USB cable and here is the 
problem. 
Since now I used with no problem BBB rev C and BBB industrial. 
Also this BBBW worked properly when recognized as BBB. (with  disabled from 
/boot/uEnv.txt)
