Hello!
Can I use two pins for power supply?
I want to made a cape for own powersupply.
If yes, which pins are + and -
And which voltage?
Thank you!

Found this in manual:
VDD_5V is the main power supply from the DC input jack. This voltage is not
present
when the board is powered via USB. The amount of current supplied by this
rail is
dependent upon the amount of current available. Based on the board design,
this rail is
limited to 1A

I am wondering if it is possible to map a pru timer to a gpio pin to drive
another device clock? I am thinking about synchronizing code on the pru
with an external device. Any reference to examples that are similar to
this would be appreciated.

Hi,
I'm using kernel 3.8.13-bone67 on BeagleBone Black,
I have a problem with serial port ttyO4 ...loopback doesn't works !
The other serial port works but not ttyO4 (Rx works but not Tx !)
Same problem with 3.8.13-bone40 and also with another same board ...

Hi Robert, William,
thanks for digging into this.
I could spend many lines explaining that this person does have some
experience in installing and configuring Linux devices such as NSLU2,
SheevaPlug and BBB, eight devices so far.
Also could I respond to all the considerations you brought up.
Hi William,
I was puzzled by what Robert wrote which I thought could be confusing to
a new user.
It was just the wording.
It happens - many a time professionally I have had the shock horror of
discovering that what I thought I had very clearly stated in
presentations, documentation and

Hi Ben,
I am also trying to enable a TFT lcd. I have done all the configurations in
the .dts and inserted the cape.
I could see the /dev/fb0 getting created and doing fbset shows the timings
all 0s.
Were you successful in having some display shown on the lcd. If yes, how
did you manage to do
Thank you for reading the manual. I ma not sure how to make the statement
any simpler.
Check the schematic. VDD is an input. VDD_SYS is an output. .
Use VDD to power the BBB in place of the power jack. Use VDD_SYS to power
the complements on your board if needed. But do not connect any signals
I believe (via email correspondence) that the people at Tindie have
been busy with the Arduino sketch for the past 2 weeks and should have
something out within the next 2 weeks (my guess at their time frame)

drivers.unfortunately nothing yet.

The new Bosch sensor really looks great! Do you know whether there are
already some arduino sketches available, as the author says in the
description at tindie? Would be cool to read some code and port them for
the beaglebone. Im about to build my own quadcopter and used the Bosch

I believe you have misunderstood me :)
The servo is powered by an external power supply at 5VDC. The signal is
from an expansion header. The ground is the same expansion header's ground.

I am having the exact same issue with my XBee cape. Strangely the

like my Python scripts don't actually talk to it at all!

I build an own cap with Inputs, outputs (relay) and Rs232.
When I put the cape on the BBB, the power LED is on, and also the CPU and

Seems the BBB CPU is on 100%?
Is it possible to setup a log while booting?

'man 5 crontab' then search for reboot is probably easiest.

For the external source, if your
BB loses power, then you'll be powering it up through the esd does in the pin
connected to that external power source. It probably won't survive.
A general rule is to never apply voltage to a devices pin unless that device is
powered up, unless it is in the

Sounds more like you may be creating an interrupt and have no SW to answer
it. You really need to get the serial cable o see what is going on.

Hi all,
Those interested in embedded development with Simulink will be happy to
