[beagleboard] 4 GByte RAM?

[mike . maikaefer]

Hi,

according to the schematics there is a RAM-module with 4 GByte available on 
the BBB (and also on the BBG). Why are there only 512 MBytes available for 
the CPU - aren't enough address lines used? Or what else is the reason?

Kind regards

Mike

Great, thanks, I'll try that :-)

[beagleboard] Cannot SSH to BBB anymore

[yassyass]

Hi guys,

Not sure what's happened and not sure where to start troubleshooting. 

My BBB won't respond to SSH requests from Terminal on my mac, this was 
working perfectly fine just days ago and I am trying to go back and 
understand what changed. 

I worked mostly using Cloud9 and running scripts with Python and JS so I 
have quite a bit saved on it that I would like to recover if possible 
before resorting to re-imaging.

The board seems to turn on fine with all the LEDs turn on sequentially and 
then they start pulsing as they would when the OS is running.

The board is both connected directly to my Mac and to a LAN via ethernet.

Re: [beagleboard] BBB: Using DMA with SPI

[Jeff Andich]

I ran into a similar issue when I upgraded my kernel on an existing BB-X15 
image and then attempted to run the flasher script from the SD card on a 
BB-X15:

http://beagleboard.org/discuss?place=msg%2Fbeagleboard%2Fx1mxG7c-ilg%2F2Q8OROMCAwAJ

Where Robert indicated to do:

(1) depmod -a

(2)  sudo update-initramfs -ck `uname -r`  (or update-initramfs -uk 'uname 
-r')


Not sure if updating the module dependency db is needed, but something to 
consider..

before you run that script, just make sure you run:

sudo update-initramfs -ck `uname -r`

Re: [beagleboard] BBB: Using DMA with SPI

[John B]

I found that the eMMC flasher (
/opt/scripts/tools/eMMC/init-eMMC-flasher-v3.sh) no longer appears to work 
after I upgraded to Kernel 4.14.x.  I traced this to 
/opt/scripts/tools/eMMC/functions.sh in *prepare_environment()*.  It seems 
that /proc and /sys are not mounted when the flasher script is executed 
from *init*.  Needless to say, this caused agita for the rest of the 
script.  I'm not sure if this has been addressed someplace else (maybe it 
has to do with the fact I am using initrd.img-4.9.82-ti-r102? I doubt it 
though.)

In any event, in case someone is running into the same issue, I have 
attached my updated functions.sh which addresses the issue by mounting 
/proc and /sys just after the script does /tmp.  This seems to work fine; 
it should even work on a system where /proc and /sys are already mounted.

Re: [beagleboard] BBB: Using DMA with SPI

[John B]

Robert,
Yes.  It seems that 4.14.x works fine.  Using a logic analyzer with 4.9.99, 
it seems that, while it was doing DMA, it was ALWAYS using a word size of 8 
bits.   So you 'd see 8 clocks, a substantial gap, 8 clocks, gap, 8 clocks, 
etc.  Using the same driver module code we used for 4.9.99 (albeit, built 
with the 4.14.40 kernel includes/Makefiles), we ran it with the 4.14.40 
kernel.  We now see the correct 32 bit transfers: 32 clocks, gap, 32 
clocks, gap.  The gap is now about 1/5th of the total time as opposed to 
half of it.

Something must have been fixed/changed between 4.9.99 and 4.14.40 in the 
SPI driver.  I'll 'diff' them out and see if I spot anything.

Thanks for the suggestion on using 4.14.x.

John

I am no longer involved with the manufacturing. I remember ordering a bunch of 
them a while back. As it says on the WIKI, if you have any questions, contact 
Jason Kridner. He is handling the manufacturing. I am not aware if they made 
any changes or not.

The BOM on the WIKI for the BBB is a .csv file, I never used .csv files so I 
have no idea where that came from and it has not been changed from the original 
design from a part number standpoint on that connector.

Hi Gerald,

thanks for the feedback. Where can one download the Altium version? I only 
found the one with the Gerber-files...

So...aren't these data open and available for free?

Any idea where I could get the latest version from? I of course would modify it 
for my own but it does not really worth to pay X000,00 Dollars for Altium just 
for my few boards...

I afraid I have to come back to this: sure this is the latest version of the 
layout? It makes use of the Alps SCHA5B0200 microSD card connector which is 
discontinued and which does not seem to have a compatible replacement!?

Hi Gerald,

thanks for the feedback. Where can one download the Altium version? I only 
found the one with the Gerber-files...

[beagleboard] Re: Recommended Microphone

Just wondering if you found a microphone that would work with the 
beagleboard system? Starting to look at the pocketbeagle for the same.

Hi - I see that Digikey no longer sells 
http://www.digikey.com/product-detail/en/BB-BONE-AUDI-01/BB-BONE-AUDI-01-ND/3503683
 

  
. 

Was looking at something which detects the amplitude and frequencies of 
sounds for a pocketbeagle- is there a part/microphone you'd recommend for 
that?

It may not be the latest. That conenctor was replaced a while back.

Re: [beagleboard] Re: Disabling/enabling the USB slave interface dynamically

[Mala Dies]

Hello,

I was incorrect on what you were attempting to do w/ your idea and set up. 
Maybe setting a reset pin would help. For instance, I use a Cape called the 
Motor Bridge Cape. Primarily, I use this Cape for testing and fun. I have 
created a mower that runs in angles until it is done but on this 
MotorBridge.py library, the idea is that it resets a pin. 

I thought using a reset pin may work. Do you think there is a way to use 
the USB as a reset pin? 

Just for kicks, I am replying, e.g. as your method of using the BBB is out 
of my scope. I am sorry.

Seth

P.S. If you get bored and you think I am on to something, do not hesitate 
to reply. If not, I understand.

 Just out of curiosity -- have you tried a Refresh 
 in the
 Windows FileExplorer that is opened on the "USB mass storage".

Re: [beagleboard] Re: Disabling/enabling the USB slave interface dynamically

[Jon Lundstrom]

I'm using my c-program that creates files. It uses the the USB-mass storage 
device that comes with the BBB which is created by 
/opt/scripts/boot/am335x_evm.sh (so, in that sense, you could say I use a 
script).
I've mounted the disc-image-file it uses, so my application simply writes 
its files to that device, for the host PC to copy.

The BBB with my application is a measuring device which produces result 
files (in the same way as a digital camera).
It would nice to be able to upload these files to a PC via USB. 

Scp could be a solution but I don't have control over the host PC, in the 
sence that I don't want to install programs on it. The PC usually belongs 
to somebody else. Simply put, I want to the ability to connect to any PC, 
have my application to create files on the BBB and then letting the owner 
of the PC to upload them to his domain.

Another solution is to unplug-reinsert the cable after every measurement. 
That's where I stand today  ...but it's not pretty. 
I feel I'm so close: I only need my application to toggle the USB device 
off/on, so the host will behave as if it was unplugged/reinserted, and 
update its file info.

But I don't know how. I have difficulties understanding the 
am335x_evm-script and it seems to be run once, at startup. Isn't there an 
easy way of turning the USB-mass- storage-device on and off from an 
application?

Yes, I have been thinking of buying a mechanical relay, controlled by a 
gpio, to unplug the cable from my application. That would probably do the 
job, but it feels awkward.
