[beagleboard] Using a BeagleBone as a Kerberos Key Distribution Center

[Greg]

Here's the documentation for a project I've been working on:

https://github.com/Greg-R/BeagleBoneKerberosKDC

This is perhaps an unusual application of a BeagleBone.  What it does is 
act as a third-party authentication server in an NFSv4 based network.
The protocol is called Kerberos, which originated at MIT in the 1980s.

I've been running this on my home system for a few months now, and the 
BeagleBone + Debian console distro is a perfect match for this application.
It's a bit unusual for a BeagleBone project, as there is no embedded device 
code, only a complex configuration required!

Regards,
Greg

[beagleboard] Re: Touch on LCD Chipsee (BBB-EXP-C) stopped respond

[Radovan Chovan]

The same problem appears with touchpad or even with mouse.
Discussion here: 
https://askubuntu.com/questions/528293/is-there-a-way-to-restart-the-touchpad-driver


Using these commands
xinput disable EP0790M09
xinput enable EP0790M09

input driver for "touch" functionality restarted and then touchscreen 
started respond again.

But, it will be useful, if there is solution with preventing of this touch 
problem.

[beagleboard] BBB working without emmc chip

[superdare]

Hello,

Is it possible to unsolder the emmc memory chip from the board and boot 
only from sd card (always boot from sd) ?
If yes, what resistors should I keep or should I make any changes in the 
board schematics ?

Any help would be appreciated.

Thank you in advance.

Re: [beagleboard] Running bbb without emmc memory chip (physically, unsoldered)

[Super Dare]

Yes, of course, with hot-air and with very much attention. I don't know 
exactly if I need to make any changes to the board schematics, to boot 
without problems from sd card.

[beagleboard] JTAG Debugging - 2 Code Composers on the Same Machine - One under Ubuntu - The Other under Windows

[Jeff Andich]

Hi,

We're not yet able to setup Ubuntu native on PC's at work, so we're using 
Ubuntu under VBOX.

I'm attempting to do JTAG debugging via CCS 7.2 to the BB-X15/am572xEVM, 
but when I run CCS in debug mode under an Ubuntu/VirtualBox, CCS hangs. 
 I'm able to view registers on the A15_0 core, but I haven't been able to 
successfully load u-boot-spl.bin built in CCS on Ubuntu.  When I load, CCS 
never comes back, and I haven't been able to specify the "load address" for 
the SPL.  From what I understand from reading an older version of TI's CCS 
wiki, JTAG debugging doesn't work well through a virtual machine.

So I'm trying a strange approach:  2, CCS 7.2 installations on the same 
machine, 1 under the Ubuntu VM to build the SPL in Linux and another under 
Windows to manage the JTAG debugging process (e.g. load u-boot-spl.bin via 
JTAG, view memory, step, etc).  But I'm having some issues using a 
Windows/VBOX shared folder to contain the u-boot tree so that both the 
Windows and Ubuntu CCS's can look at the same tree/project.

Has anyone on this forum successfully tried this kind of thing before or 
are there obvious reasons why this is a bad idea??  

I think the person in the following thread may have tried something like 
this??

https://e2e.ti.com/support/development_tools/code_composer_studio/f/81/t/117880?tisearch=e2e-quicksearch&keymatch=virtualbox%20shared%20folder

I may post up on TI/E2E, but we're working with the BB-X15 image, not the 
TI SDK image.  I'll try to annotate this thread with any useful information 
that's thrown our way.

Thanks!!

Jeff

If you're serious about your work. Buy a cheap laptop, and install Ubuntu
on it.

[beagleboard] Re: Remove the TPS65217 driver from the custom built kernel

[Angelo Fares Menhem]

Hey Guys,

The problem of using a LiIon battery to allow BeageBone boards to orderly 
shutdown is object of several posts here. 


In my particular case I just want to use the battery power to allow 
shutdown and disconnect the battery from the power path at the end of power 
down sequence to work around the problem of VSYS being kept with 4,1 V 
causing VDD_3V3A to set to around 0,8V.


As I don't intend to run on battery nor on USB, I came up with this 
solution and I would like to have your thoughts in why it didn't work 


The whole idea is to connect the battery in the USB input of the PMIC 
(instead of BAT terminal) allowing battery power to be 
connected/disconnected using power path control bit D4 in the Power Path 
Control Register (PPATH). With this I can change the shutdown routine of 
the OS to disconnect the battery power from VSYS  just at the end of the 
power off cycle, before issuing the POWER_EN Signal.


As the battery still needs to be charged, my idea is to connect BAT SENSE 
to the battery (+) and connect BAT to BAT SENSE via a low Vf diode in order 
to prevent the battery from supplying the original power path. It should 
work because the charging cycle tests the battery presence sending a small 
current to it and sensing the voltage (via BAT SENSE I suppose). Naturally 
TS is supposed to be connect do a 10K resistor to ground.


However, it didn't work! PMIC just didn't turn on when AC input is connect 
to a suitable  5V power supply.


Below is the circuit:





Does someone can explain why not?

Best regards

[beagleboard] Re: My overlay can't find clk_mcasp0

[Mike Davis]

I have the same issue.
I am running kernel debian with kernel 4.4.52-bone16
I pulled down RobertCNelson's dtb-rebuilder from 
https://github.com/RobertCNelson/dtb-rebuilder 
,
 
branch 4.4.x and rebuilt all the arm dtbs and installed them.
Then added then updated my *base* dtb, which

as per

Reboot, then install the audio: sudo sh -c "echo BB-BONE-AUDI-02 >

[beagleboard] Re: JTAG Debugging - 2 Code Composers on the Same Machine - One under Ubuntu - The Other under Windows

[Jeff Andich]

Trying to get IT to allow me to put Ubuntu native on a corporate PC. 
 Another guy higher up the food chain told me to just try booting an 
existing desktop PC with an Ubuntu USB stick... 

Also, someone just loaned me a laptop with Windows 10, and I've got an 
Ubuntu bash shell up from the Windows Linux Subsystem/Ubuntu bash shell. 
 Am going to try installing Xming, CCS, the JTAG drivers, and see if 
Windows 10 will allow CCS to talk to the debug probe and to the target... 
 This could be worse than the virtual machine idea


Thanks!  jeff

Re: [beagleboard] JTAG Debugging - 2 Code Composers on the Same Machine - One under Ubuntu - The Other under Windows

['Mark Lazarewicz' via BeagleBoard]

Don't you want to load the output generated with debug info not the .bin? I've 
used a lauterbach emulator to load uboot for source level debugging. You need 
to point to source tree where you built uboot. If I recall correctly we used a 
dual boot Ubuntu machine at work. We built in Ubuntu and used CCS in windows 
and had a mount to a shared partition. At that time uboot debugging was 
possible in linux but I believe we had the linux drivers for the jtag from 
either TI or Lauterbach. I think using a virtual machine your gonna have issues

Re: [beagleboard] JTAG Debugging - 2 Code Composers on the Same Machine - One under Ubuntu - The Other under Windows

[Jeff Andich]

Thank you!

Yes, I would think symbols would need to be included to break on functions, 
but I believe the video I watched (TI board port series modules 6,7) 
specified to load the bin file after switching CCS into debug mode.. When I 
get a native linux machine setup, I'll be able to report back. Going to try 
that tomorrow, but then there's that corporate network thing...

[beagleboard] "What Was I Thinking" and Learning How Sensors Might Work/Seth

[Mala Dies]

Hello,

I know I have bugged the community with issues pertaining to my TMP36 
sensor and its technology and the BBB (and all variants "sometimes 
including Capes").

Here goes:

...cough.

Um, Why would I attach a male to male lead from 3.3v on the BBB to GND on 
the TMP36 sensor?

Easier:

*BBB* (3.3v) or P9_03 *to **TMP36* (GND) or Pin 3

I think this is my question. Please try to answer with some type of 
understanding for me.

Seth

P.S. I have found some more items regarding this TMP36 sensor, i.e. like 
why I am attaching the lead to the BBB on GND_ADC to TMP36 on Pin 1? I 
found the info. to the TMP36 sensor 
at 
http://www.analog.com/media/en/technical-documentation/data-sheets/TMP35_36_37.pdf.
 
Anyway, if you have time one day, please try to make me understand. I 
thought GND goes to GND with the lead for some reason.

[Mala Dies]

Hello Again,

Seth here. Um, *node* is not found on my version of stretch. I just tried 
to run a .js file on the BBB and it replied to me saying that *sudo: node: 
is not a known command*. What gives? Does anyone have an idea as to what is 
happening?

Seth

P.S. Should I get a new *node* version?

"nodejs"

(in debian an older binary package had already used the binary "node" name..)
