My objective is to poll sensor output using GPIO and process the data. The
CPU is missing some of the pulses from sensor while processing the previous
data. My idea is to use PRU to count the sensor pulses and provide the
counter value to CPU using shared memory. I am using C code for PRU after
Hi Robert,
How I can install Ubuntu 12.04 / 12.10 when it had been EOL?
Thanks!

I have an application that needs a XBee and another module to be turned on
and off digitally via a BealgeboneBlack.
The Setup is 2 XBee's and an application board is connected to the

UART and a GPIO for the power state . When the System is Powered ON I need
1 Xbee and the

want to add another 8GB 8bit Nand flash using GPMC. We are using same data

We are using MT29F64G08CFACA chip for 8GB NAND flash.
Is there any support of

I've just purchased a beaglebone black for the purposes of learning

I'd like to experiment with real-time processing, rt-linux, etc. And

second component is running along the long dimension of the board, toward

For awhile now, in u-boot we defaulted to a usb-eth gadget on the slave port.
I'm switching that to the UMS or USB Mass Storage
The eMMC does not use GPMC. It use the MMC function on those pins. Only one
device can be supported on those pins. If you want 8G your best bet would
be to replace the 4G part with an 8G part.

Also works fine with USB2 connections.
Works fine on both Ubuntu and Windows hosts.

The PRUSS don't cause any CPU usage. You can reduce CPU usage by adding a
nsleep() call to your while loop. Anyway, the max. speed of pulling the
GPIO state (as in your while loop) is limited to approx. 140 kHz.
An alternative is to configure a GPIO interrupt
1. Map an interrupt to any
I got it solved. sudo nano /usr/share/xsessions/lightdm-xsession.desktop change

file: sudo nano ~/.config/openbox/autostart and add the following:
If you are using the regular and pro 2.4GHz XBee you don't need anything
close to 1A. The hardware pin sleep is so low power that turning it off
makes little sense. Just my two cents from the guy who builds low power
hacking drones.

Robert, so this would work in a pinch to modify files on the system in a

Pretty nifty either way I think.
So what about a possible g_multi, or even just g_serial for observing

you're looking for /boot/uEnv.txt I think is the current location on the

And then you do . . .
