It looks like BBB is selling like hot cakes.
I would like to order a couple of them and Mouser, Radionics, Digikey and
Avnet are all out of stock.
Does anybody know when a new batch will become available?

Thanks, Gerald.
That's an Element 14 BBB.
What about CircuitCo's BBB?

Hi,
I have just commented both lines, and the process goes well until console
starts to show:
*INIT: Id "T0" respawning too fast: disabled for 5 minutes*
Then, the process enters into an infinite loop showing message every 5
minutes.
What process is T0? And how can I solved this?

Your options are element 14 or arrow. You won't be able to find circuitco in
stock anywhere until July.

Hi,
I'm currently diagnosing a Beaglebone Black (A6A) failure. It's been
running for a few months at about 20% cpu load on average. Yesterday I was
looking into some intermittent ethernet issues (may be unrelated to this
issue) and, after power cycling it, I was not able to communicate with it
Also the u-boot messages seem mangled. Not sure what would cause that -- if
it's a problem with my serial connection I would expect to see further
mangling once the kernel starts to boot, and on the initramfs prompt, but
that all seems intact.

Shutdown Linux before powering down.

I tried it again without microhdmi / usb keyboard connected, and got intact
messages from U-Boot.

Hi,
I'm examining a beaglebone black failure.
Brief background:
- This beaglebone black (rev A6A) has been running for roughly two months
- The beaglebone was powered by a 5V/1A power supply through the barrel
connector
- CPU usage was around 20% usually throughout the time period
- Ethernet wa
So you are implying this is a corrupt filesystem issue?
I won't be able to guarantee power failures won't occur during runtime for
this application, but if this is a corruption issue I don't have a problem
making the root partition read-only.
Chris
On Wednesday, February 3, 2016 at 2:09:20 PM
That would be my guess. Yes, making it read only will help. Or attach a
battery that can keep it powered up until shutdown can occur, and have the
kernel shut it down. A lot of discussion in the forum on this topic.

I'm now trying to re-flash the eMMC, but every time I try, after a few

which worked fine.

I am not sure why the system is not acquiring address 0x20.
I would try removing the space after the comma, in line '
*compatible = "nxp, pca9535";'*for address 20 so that it is identical to
the lines that do working.

Robert,
I'm using a 5V/2A power supply, and have tried the same process with the
identical setup across multiple boards (same power supply, same uSD). I'm
not seeing the power supply dip below 5V at all during the flashing
process; it's steady at 5.20V throughout the process. Maybe that's on th
My kernel version:

I'm having trouble getting PWM and UART5 to work at the same time with

Black.

I don't understand how to convert voltage in temperature.
My sensor is a IR temperature sensor with 5 V DC power supply

My beaglebone cannot support an output (0-5V) so I've used this voltage
divider.
I've calculated the resistor R1=634 Ohm (5% so it's not so

That worked! Thank you very much. You just saved me several hours
