Beaglebone black ssh problem

[l.ha...@gmail.com]

Hi, I am using beaglebone black with wifi usb dongle. 

While I was working on connecting wifi network using wifi usb dongle, I edited configuration file and my beaglebone stopped working.

I tried to ssh using putty and I can't even connect to ssh (ssh login window is now displaying).

I believe that I did something wrong with configuration file and I do now know how to resolve this issue.

I am very new to beaglebone black and I need some help.

I would greatly appreciate it if someone help me..

Thank you

A highly recommended accessory is a USB to serial adapter cable.  It will need to be the 3.3volt version, like this example:

There is a 6-pin header on the Beagle Bone which you can plug this adapter cable into.  The other end is USB, and then you will need a terminal program on the computer.

I use a Linux terminal emulator called screen.

When you connect in this way, you will have full access to the file system and you can fix whatever it is that got changed.  This method bypasses the complex networking stuff like USB or Ethernet.

Another very practical approach is to use the Micro-sd memory cards and do not flash to the onboard flash drive.

Be sure to get a ruggedized card and it will be more reliable.  I'm done with the cheap cards, they will waste your time.

When you get to the point where your software is solid, you can flash to the onboard drive.  This will be the ultimate reliability.
