Hi!
I am sometimes wondering why there seems to be little to no attention that
there is not standy-mode on ARM-plattforms when using pure linux? Sure,
energy consumption is considerably less when compared to x86 plattforms,
yet it would relieve thermal stress of the often closely integrated
Managed to successfully install DirectFB (specified *omap* for the video
driver) on the BBB. However when I tried to run the sample JavaFX 8 program
the following errors appeared:
cmd : cd '/home/debian/NetBeans_Projects//JavaFX_Test';
'/home/debian/ejre-1.8.0_fx/bin/java'
Reinstalled DirectFB with the video driver set to *none*. Ran the sample
JavaFX 8 program with similar errors showing up again:
cmd : cd '/home/debian/NetBeans_Projects//JavaFX_Test';
'/home/debian/ejre-1.8.0_fx/bin/java' -Dfile.encoding=UTF-8
-Djavafx.platform=directfb -jar
Correct me if I'm wrong, but something like this can be used to communicate
with BBB's USB to Arduino's I2C pins. Correct?
Can you tell me what the plug number is. I would like to use some parts I
have and build a power supply for my bbb.

Thanks for the info, Jerry. Those resources will definitely come in handy.
Is it possible though to use the BBB's USB port instead of the GPIO pins? I
don't have any GPIO pins available because I'm using an Octoscroller cape
(image link below).

Dear All,
I'm trying to communicate on SPI from FPGA to Beagle bone.
I need to send array of floating point number, of length 38. (*float* data[38];
)
But when I'm trying to send. spi0_cs goes high after 9 words transfer.
Means, I'm getting only 9 words of 32-bit each.
I have kept 500Kbps

Can you run fdisk –l ? It should show you the physical partitions on your
system. The onboard MMC should be 4gb. If you have a microsd chip in there it
would show up too.

These are most likely bad boards sent out by Circuitco that are actually
Rev B boards with Rev C labels on them. If you think you have one, request
an RMA immediately if not sooner and it will be replaced..

I added a 232PTTL33 converter and now communication to the beaglebone works
but communication from it to the computer doesn't work. The converter
definetly is an improvement but not a complete solution has anyone else had
good luck with it?

these units powered by the signals on pins 7(RTS), 4(DTR), and 3(TD).
These handshake lines can be in either the high or low condition, but *must
be present* to power the converter.
If there is no adequate power, generating the necessary RS-232 voltage
levels does not work.
so... are RTS
If you want to use the triggers provided by the led interface, use the led
interface. The pin will go high or low voltage with the led interface or
gpio interface.
GPIO is for general purpose io, so it's not going to have fancy patterns
or anything, just on, off, in, out.

Thanks, I'll do that with all 3 boards, I guess. I wonder why
element14/Embest would tinker with the original firmware...
Since the Debian image is for 2GB eMMCs, does the filesystem need to be
resized after flashing it to a 4GB eMMC, or does the flasher script take
care of that?
