Greetings--- I have experienced this problem before. It is likely an issue
with the physical interface, not software. Basically the issue is that
the receiver is still receiving when the line goes to an idle undefined
state, and receives "garbage" data. Search for RS 485 failsafe bias for

Updating every minute risks wearing out your emmc flash storage, especially
if you do a 'sync' afterwards. I used 6 hours, and of course I updated the
timestamp at shutdown.

For ADC power supply, the AM335x datasheet lists VDDA_ADC recommended
operating range as 1.8v +/- 5% (Table 3-12), and absolute max as 2.1v
(Table 3-1).
For ADC signals inputs, the max range is listed as 0-VDDA_ADC (Table 3-17),
so it should not exceed the input power supply level. No

You make a good point...I thought that the GPIO were configurable between

If you're using Angstrom, then get the timestamp-service package. It

Same here. I have a normally-stable microUSB connection, but if the
connector is bumped, the connection can be disrupted (both power and data).

No, you can't easily flash over ethernet, wifi or USB.
However, if you just want to add control features over time, you don't need
to completely reflash a new image to the device. You can copy executable
code or data to the device using the network, and then it is basically
installed. I have
I'm not sure how people normally deal with this. On a different linux
machine (not BBB), I have several USB serial adapters attached and I need
them to be assigned specific device names so that software can find them.

Well, if the MMC is corrupt, it's corrupt. There are no buttons you can
press to solve that problem: you have to reflash.
Holding down the reset button only prevents corruption in the future.

I agree, this is a confusing situation. I have installed the 2013.09.12
version without incident, but apparently the 2013.09.04 is the officially
supported version.

If the firmware update uSD is bootable, upon booting you should see all

So the first thing I'd worry about is that you used the proper steps to

In case it's not, you should mount it first,
