Re: [beagleboard] Re: Non OS application
Hi Charles, I did read the TRM. Chapter 26 named Initialization. It does have quite a good info which tells how system starts up how many time of booting is there. I thought this forum is to help people rather enhancing the sarcasm skills. I know about the different kind of booting, memory addresses of all exception vectors in RAM and ROM. My only question is what address I should place my application's entry point so that at startup my application gets executed. Thanks for your help anyway Charles.

Re: [beagleboard] Oh No!!! Did I brick my board?
Thanks...I'm familiar with that page. However, the only links for Jessie img files are Testing Snapshots. Would these be the same as the official release (as far as libraries...I want to make sure I can cross compile openCV)? Is the image I'd get with sudo apt-get install linux-image-armmp the same as one of these snapshots, or is it an official release? If it's official, and if I updated with one of those img files, could I then install as above?

Re: [beagleboard] Oh No!!! Did I brick my board?
Thanks everyone for the answers. One final question: What I'm ultimately trying to accomplish is developing a custom app w/ openCV in Eclipse on a PC. And cross-compiling for the BBB. From what I understand (from Derek Molloy), getting emdebian, cross-compiling, and openCV working on Wheezy is much more difficult than on Jessie. That's why I chose Jessie for my VM on my PC. However, there's no bone Jessie yet (if I understand everyone's help so far). So, are my only options: 1. Put a Wheezy VM on my PC and try to muddle through the setup? 2. Wait for a full bone Jessie?

One final question: What I'm ultimately trying to accomplish is developing a custom app w/ openCV in Eclipse on a PC. And cross-compiling for the BBB. From what I understand (from Derek Molloy), getting emdebian, cross-compiling, and openCV working on Wheezy is much more difficult than on Jessie. That's why I chose Jessie for my VM on my PC. However, there's no bone Jessie yet (if I understand everyone's help so far). So, are my only options: 1. Put a Wheezy VM on my PC and try to muddle through the setup? 2. Wait for a full bone Jessie?

RE: [beagleboard] ESP8266 linux driver
wondering about using the cheap esp8266 module with BeagleBone black,
but I couldnt find anything about it in the web. I understand that this is a
bit
differebtly working device than the wifi usb dongles (i gues its more SoC),
but havent anyone though of using it with bbb? The board uses only uart
lines, that would be very efficient and cheap.
What do you need to know? The device does look exactly like any old
modem/terminal. Problem is they are slow. Whilst great for sending modest sized
messages ('Hello World') they will not cut it for streaming video.
Try hooking one up to a PC with a USB serial adapter - you'll get an idea of
capabilities pretty quickly.

If you need to build from source, just clone: https://github.com/RobertCNelson/bb-kernel/tree/3.8.13-xenomai ...and run ./build-deb.sh. You'll get a compiled kernel, *.deb package, and a full source tree for experimenting. 3) *Motor test* - My intention is to run some motor tests with Xenomai and without and compare performance. Do you have any recommended Xenomai-specific tutorials using motors or for any actual use case of the kernel in action on the BBB? Although I recognize that much of your wonderful MachineKit work is about driving motors, I've found very little on the subject showing simple usage without capes or without MachineKit. Motor test is a bit vague. You can drive motors _many_ different ways, from sending packets via Ethernet or CAN to controlling hardware PWMs to interacting with the PRU to twiddling GPIO pins.

[beagleboard] Re: i2c question (BBB)
There is an 8 bit representation of an I2C address, where the bottom bit is actually the Read/Write bit and is, by convention, set to zero to describe the address. There is a 7-bit representation of an I2C address, where the address is shifted one bit to the right, so the read/write bit disappears and is not part of the address. Half the manufacturers do it one way, the other half the other way. Linux/Debian uses the 7 bit representation. 0x42 1 = 0x21 --- Graham == On Wednesday, June 24, 2015 at 3:13:48 AM UTC-5, 멘지 wrote: I'm trying i2c bus on BBB slave module is OV7670 ( CMOS Camera ) OS is angstrom https://lh3.googleusercontent.com/-zT9VFvtWOmo/VYpkZj8P2MI/FDw/Abor6TYsMrg/s1600/dd.png when i connect ov7670 on BBB P9 Header (19,20) and command i2cdetect -r -y 1 look at the picture above you fine '21' is creating 0x21 is slave address but slave address of ov7670 is 0x42 in datasheet what means 0x21 ?? and am i better try i2c ???
