Ah, thank you. That's what I needed to know. Going to look into supplying
power over USB (only).

Thanks,

[beagleboard] BBB won't mount via usb with latest images. Please help

[Arlin Vanderbilt]

I recently dusted off my Beaglebone black which I purchased back in 2013 
for a project at our makerspace. After considerable difficulty trying to 
connect to wifi I decided it might be prudent to upgrade to one of the 
latest firmware images. 

So I loaded the 2015-3-1 Debian image onto an SD card and booted from that. 
The first thing I noticed was that the board wouldn't mount when connected 
to a laptop by usb cable. Which, of course means I couldn't connect to 
beaglebone.local or 192.168.7.2. However, I was able to determine that 
linux appeared to be operating fine otherwise as I was able to ssh in via 
ethernet and serial with no problems. Thinking that maybe it was a Debian 
problem I also burned the 2013-6-20 Angstrom image to an SD card and booted 
off that. Once again it appeared fine via ssh but I couldn't mount the 
beaglebone or connect to beaglebone.local.

The original 2013 eMMC flashed os is still on the bbb. I can still boot 
from eMMC and mount the device and connect to beaglebone.local as expected.

Can anyone tell me what's going on here? Is my slightly old BBB not 
compatible with the latest images? Or are there some limitations with 
operating from the SD card that I'm just not aware of?

It is NOT grounded by default otherwise you would not be able to power the
board from USB. I don't know how you can ground the Vbus line. I would take
a soldering station (I have two) and put a simple short from the Vbus pin
at a USB connector to the ground.

OR you can power the board from USB and ensure that no random reboots
occur. The problem appear when Vbus line is floating

grrr, and as usual . . . I keep forgetting to comment on stuff I've been
thinking about all day, in one post :/

My "concerns" about systemd are long gone now. Every one of these
linux-images I've run have booted up, and stayed using systemd.

The rootfs is Wheezy 7.8 for what that's worth. But Robert already said

Re: [beagleboard] Re: BBB power led blinking, revived after several power button presses

[Gerald Coley]

If you do not use it properly, it will be damaged. That applies to every
electronic circuit ever designed. I would have stopped using the circuitry
after the second try.

I would be happy to look at your circuit and see if I can identify what the
issue might be.

Re: [beagleboard] Re: BBB is a great home server but printing is a challenge

[kantonus]

Hello Yves,
It is nice to know that it is really possible to make this setup work. I 
have struggled with this quite some time without success. My BBB runs 
Ubuntu 12.04 and CUPS 1.5.3 and I can log into its web site and add 
printers and printer drivers. All is fine - but - I just cannot print. 
Printing on a client returns something about waiting for authentication, 
and printing from the console of the BBB returns "lp: Not allowed to print."
I have searched and followed various recipes without success. And I have a 
feeling that my cups.conf is still not 100% correct. I wonder if you might 
have some hint up your sleeve - maybe a working sample cups.conf that I 
could use to test on or something else that can get me out of the swamp.

Cheers
Gunnar

Re: [beagleboard] Re: BBB power led blinking, revived after several power button presses

[rosenbloomaj]

Gerald: I have 2 BBBs that will give a single brief flash of the power LED 
when the power button is pushed, as described by others. It will not 
sustain the power LED on nor boot up. When I power it from the barrel 
connector (Adafruit regulated 5v power source / AC to DC 5v 2A) while on a 
digital volt / ammeter, no current flow registers at all during the brief 
flash of the power LED. The voltage reads 5.08 volts. I cannot see that 
this is due to either an unregulated power source (also happens on USB 
power on 2 PCs by the way). Nor does it look like excessive current draw. 
Other ideas?

Re: [beagleboard] Re: BBB power led blinking, revived after several power button presses

[rosenbloomaj]

I now have 4 damaged or dead BBBs. On this last board (Element 14), I had 
only a stepper motor driver board connected (Pololu DRV8834), and nothing 
else. The DRV8834 was initially drawing power from the VDD5v on the BBB. 
The BBB "blacked out" twice while nothing was happening and while connected 
to both a 5V regulated power supply (Adafruit) and USB power. I was worried 
that the DRV8834 was drawing too much power (although I have found it uses 
< 200 mA @ 5V), so I used a separate power supply for the DRB8834. Only the 
logic of the DRV8834 was hooked up to the BBB - nothing that would supply 
power and no analog inputs.  The third blackout also occurred without an 
obvious precipitant - again with both power sources connected (USB and 
barrel plug). Now the power LED flashes briefly when either USB or barrel 
plug power (Adafruit power source for BBB) is connected to the BBB. It will 
not sustain the power button nor boot up.

This seems to be a repetitive theme on this forum. I am losing faith in the 
BBB ever functioning in a real world environment if it is this fragile. Is 
there any way to protect the BBB processor (or whatever is blowing) with 
external circuitry or power?

Appreciate any help. I'm now out over $200 with these boards and I cannot 
identify anything that should be damaging them. Considering changing to 
another system at this point. Although I am impressed with the capability 
of the BBB, I would not call it a robust system.

Help!

 First, I checked if my BBB was still alive. To find that, I connected my

 normally. Then to make sure that everything was properly, I ran some 
 program as given in the BB website 
 http://beagleboard.org/getting-started.  I was happy to see, the 
 programs on the website worked just fine on my board. Thus, I was able to 
 conclude that strangely, my BBB board didn't like 5V external power source!

Re: [beagleboard] Re: Debian 8.1 / kernel 4.1.x test releases are unstable

[William Hermans]

You all read the "BBB intermittently rebooting" post ? Maxim was saying a
similar problem was happening to some with the 3.2 kernel. Then grounding
vbus or vUSB made the problem go away.

Not sure if this will fix it for all of you, but I can say that I am
powering via USB, and have had zero problems with the same kernels you all
are. Also I have been assuming you all are using the 5v barrel jack . . .

[beagleboard] Re: I2C driver by PRU

[Gianfranco Rosso]

I finally installed CCS6 and use USB100v2 JTAG interface (after soldering 
the header into BBB pads).

It looks like as I2C1 module never goes out of reset status: RDONE flag 
into I2C_SYSS register is always 0 even after writing I2C_EN=1 into I2C_CON 
register (and also, SRST=0 into register I2C_SYSC).
The very odd thing is that if I read register I2C_CON it results 0, as if 
the SBCO instruction didn't write it effectively.

Is there some write-protect lock to deal with?

It should not get damaged because PMIC should handle voltage up to 20V as

Re: [beagleboard] Re: Debian 8.1 / kernel 4.1.x test releases are unstable

Sorry, I did not recognize that there are two more BB-White on my table:

root@bb5435:~# cat /proc/device-tree/model
TI AM335x BeagleBone
root@bb5435:~# uname -a
Linux bb5435 4.1.0-rc8-bone9 #1 Wed Jun 17 00:05:43 UTC 2015 armv7l 
GNU/Linux
root@bb5435:~# uptime
 07:57:01 up 7 days, 12:42,  2 users,  load average: 0.00, 0.01, 0.05

root@bb66:~# cat /proc/device-tree/model
TI AM335x BeagleBone
root@bb66:~# uname -a
Linux bb66 4.1.1-bone9 #1 Tue Jun 30 06:09:30 UTC 2015 armv7l GNU/Linux
root@bb66:~# uptime
 07:59:39 up 6 days, 21:02,  2 users,  load average: 0.00, 0.02, 0.05

They do not all run since the same power-on time, so uptime might be 
different due to time of actual first startup.
