+ <h1>Initial BBB setup</h1>
- <h2>Setting up the 3.3V DC PSU</h2>
- <p>
- With my PSU, first I had wire up the mains power cable. Any clover or kettle lead will do. Cut the end off (not the one
- that goes in the wall, but the kettle/clover connector).
- Strip the protection away by a decent length, then strip the wires inside so that a decent amount of
- copper is shown. Then wire up earth/live/neutral. This will vary according to what country you live in
- and/or the colour codes that your cable uses inside. <b>Make sure to get this right, as a botched job
- could result in extreme damage to you and your surroundings. Here's what mine looks like after wiring up
- the power cable: <a href="images/x200/psu_power.jpg">images/x200/psu_power.jpg</a> - also, make sure
- that the plug (for the wall) has the correct fuse. In my case I had a 240V wall socket, and the device
- says that it accepts 1.5A at that voltage, so I used the smallest fuse available (3A). For 110-120V the device
- says it needs 2.8A.</b> Also, if yours looks like in the image linked above, make sure to wrap electrical tape (lots)
- around it for safety. (otherwise, don't touch the terminals while the PSU is plugged in).
- </p>
- <p>
- Now take a red and black 20cm female-female jumper lead, and cut one of the ends off. Strip away the bare copper by about 1 or
- 1.5cm so you get this: <a href="images/x200/stripped_jumper_lead.jpg">images/x200/stripped_jumper_lead.jpg</a>.
- </p>
- <p>
- Black goes on -V, red goes on +V. In my case, I removed those screws from my PSU like this:
- <a href="images/x200/psu_screws_removed.jpg">images/x200/psu_screws_removed.jpg</a>. Then,
- </p>
- <p>
- Then I twisted the exposed copper on the jumper leads (so that they don't fray), and wrapped each to one of the
- screws each, around it near the head. I then screwed them in:
- <a href="images/x200/psu_jumper_leads.jpg">images/x200/psu_jumper_leads.jpg</a>.
- </p>
- <p>
- If you are using a different PSU, then the steps will change from those above. Anyway, once you are satisfied,
- continue reading...
- </p>
- <h2>Setting up the BBB</h2>
- <p>
- Since it's a bare board (no case) and you are also touching inside your X200, you should be earthed/grounded.
- <a href="images/x200/strap.jpg">images/x200/strap.jpg</a> shows how I earthed myself. This is to prevent you
- from causing any ESD damage. The surface that you place components on should also be earthed/grounded.
- (for this, I used a shielded ESD bag with a wire, copper exposed, attached from the bag to the exposed metal
- part on a radiator, which was earthed - not professional, but it should work. see <a href="images/x200/mat.jpg">images/x200/mat.jpg</a>).
- Most people ignore this advice and don't ground/earth themselves, at their own risk. You should also store the BBB
- in a shielded anti-static bag when you are finished with it.
- (the principles above apply to any computer components, since they are extremely sensitive te ESD).
- </p>

- These instructions may or may not work for you. They are simply the steps that this author took.

- setting up SPIDEV on the BBB: <a href="http://elinux.org/BeagleBone_Black_Enable_SPIDEV#SPI0">http://elinux.org/BeagleBone_Black_Enable_SPIDEV#SPI0</a>
- - If you only setup SPI0, you don't have to disable the HDMI out. (you only need one).
- That guide is for seting up the device overlay for SPIDEV, last part is to make it persist across reboots.
- Needed to turn the BBB into an SPI flasher.

- Don't bother modifying uEnv.txt. it won't work;
- use the workaround here instead: <a href="http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Loading_custom_capes">http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Loading_custom_capes</a>.

- up to (and excluding) the point where it tells you to modify uEnv.txt
- </p>
- <p>
- You need to update the software on the BBB first. Before being able to use apt-get,
- I had to use the workaround defined <a href="https://groups.google.com/forum/?_escaped_fragment_=msg/beagleboard/LPjCn4LEY2I/alozBGsbTJMJ#!msg/beagleboard/LPjCn4LEY2I/alozBGsbTJMJ">here</a>:<br/>
