I think we're talking at cross purposes here. I just want a BBB that boots very
fast. Secondarily, I want to maximize space on the eMMC for content. Thirdly,
I'd prefer to do builds on a host computer, not on the BBB. It's slow, and
requires a bunch more stuff to be installed on it.

Well in your application you would need another small CPU monitoring

there is a battery cape that does just that. I have a design that does

I should have been more clear.
I am feeding power into the Beaglebone via P9 but I could switch to the barrel
connector fairly easily.

Hello
I assume you are using the barrel connector. Could you use the USB
connector to provide power? I find a different result on my BBB if I use
the USB vs the barrel.
or perhaps I don't fully understand your issues ???

Hello List:
I have a problem that I didn't anticipate.
I have an embedded system with battery backup.
Actually it runs off of the battery and external supply keeps the battery
charged.
Here is my problem:

Get some Orange LEDs and put them in the box under dimmer control.
Tell them the "boot delay" is the filaments warming up.
Why do you need 1 second? :-)
I time a BBB Rev C, booting off a uSD card with Debian 7.7 Console up and
running in 20 seconds.

It takes my beaglebone ~70seconds to fully boot. Looking at "dmesg" it
seems like most of that time is spent setting up / loading network
functionality. I do need the ethernet connection but is there a way to
speed up the process...?

Well, it works. Remember, these signals are 3.3V and the threshold on the
HDMI chip is for a 1.8V rail.
Feel free to try the series resistors if you like.

I checked mdio:00 and 01. 00 is there and has same SMSC info, 01 is not

We would like to use the BBB as part of a prototype for a product
re-design. We will need the BBB to be a client device. I have not yet
been able to determine how I can change the VID/PID on the USB client port
so that a different USB driver will get loaded into the host. Can anyone
tell me
Hi Charles,
I don't understand exactly what do you mean here:

one GPIO read with the PRU each loop of the encoder logic. This adds about
160 nS to the loop time, but if the PRU isn't doing much else you should

Please reference paragraph 5.10 on p37 of BBB SRM.
Does memory device contamination occur due to open files in the Linux OS,
or due to improperly sequenced power to a memory devices inadvertently
writing to a memory device?
Thanks,

As to power savings in your application, which at this point is a mystery,

Dear Pedro,
I will use my BBB to connect it to the OBD interface as well as with an
802.15.4 WSN. So I will need a simple voltage conversion 12V vehicle
battery -> 5V BBB, the integration of an OBD controller ,and an interface
to my WSN. Nothing really complex but I won't be able to have it before

I had a problem using the latest TI kernel and the windows USB/ethernet

windows driver expecting RNDIS where the kernel USB gadget support was
configured to support both CDC ECM and
RNDIS by default. Changing the USB gadget support to just support RNDIS
