Initial BBB setup

-

Setting up the 3.3V DC PSU

-

- 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. 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: images/x200/psu_power.jpg - 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. 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). -

-

- 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: images/x200/stripped_jumper_lead.jpg. -

-

- Black goes on -V, red goes on +V. In my case, I removed those screws from my PSU like this: - images/x200/psu_screws_removed.jpg. Then, -

-

- 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: - images/x200/psu_jumper_leads.jpg. -

-

- If you are using a different PSU, then the steps will change from those above. Anyway, once you are satisfied, - continue reading... -

-

Setting up the BBB

-

- Since it's a bare board (no case) and you are also touching inside your X200, you should be earthed/grounded. - images/x200/strap.jpg 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 images/x200/mat.jpg). - 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). -

-

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

-

- setting up SPIDEV on the BBB: http://elinux.org/BeagleBone_Black_Enable_SPIDEV#SPI0 - - 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: http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Loading_custom_capes. -

-

- Follow the instructions at http://elinux.org/BeagleBone_Black_Enable_SPIDEV#SPI0 - up to (and excluding) the point where it tells you to modify uEnv.txt -

-

- You need to update the software on the BBB first. Before being able to use apt-get, - I had to use the workaround defined here:
- - Replace the contents of /etc/init.d/led_aging.sh with: -

-
-#!/bin/sh -e
-### BEGIN INIT INFO
-# Provides:          led_aging.sh
-# Required-Start:    $local_fs
-# Required-Stop:     $local_fs
-# Default-Start:     2 3 4 5
-# Default-Stop:      0 1 6
-# Short-Description: Start LED aging
-# Description:       Starts LED aging (whatever that is)
-### END INIT INFO
-
-x=$(/bin/ps -ef | /bin/grep "[l]ed_acc")
-if [ ! -n "$x" -a -x /usr/bin/led_acc ]; then
-    /usr/bin/led_acc &
-fi
-
-

- Run apt-get update and apt-get upgrade then reboot the BBB, before continuing. -

-

- Run those commands:
- # echo BB-SPI0-01 > /sys/devices/bone_capemgr.*/slots
- Then I did:
- # ls -al /dev/spidev0.*
- ls: cannot access /dev/spidev0.*: No such file or directory
- Then I rebooted and did:
- # cat /sys/devices/bone_capemgr.*/slots
- Output: -

- 5: ff:P-O-L Bone-Black-HDMI,00A0,Texas Instrument,BB-BONELT-HDMI
-
-

- And then:
- # ls /lib/firmware/BB-SPI0-01-00A0.*
- Output: -

-
-/lib/firmware/BB-SPI0-01-00A0.dtbo
-
-

- Then:
- # echo BB-SPI0-01 > /sys/devices/bone_capemgr.*/slots
- # cat /sys/devices/bone_capemgr.*/slots
- Output: -

- 7: ff:P-O-L Override Board Name,00A0,Override Manuf,BB-SPI0-01
-
-

- Then check if the device exists:
- # ls -al /dev/spidev0.*
- Output: -

-
-ls: cannot access /dev/spidev0.*: No such file or directory
-
-

- It didn't exist under that name, but I then did:
- # ls -al /dev/spid*
- Output: -

-
-crw-rw---T 1 root spi 153, 0 Nov 19 21:07 /dev/spidev1.0
-
-

- Now the BBB is ready to be used for flashing. Make this persist - across reboots:
- In /etc/default/capemgr add CAPE=BB-SPI0-01 at the end - (or change the existing CAPE= entry to say that, if an - entry already exists. -

-

- Now you will download and build flashrom on the BBB.
- # apt-get install libpci-dev pciutils zlib1g-dev libftdi-dev build-essential subversion
- # svn co svn://flashrom.org/flashrom/trunk flashrom
- # cd flashrom/
- # make -

- -

- Now test flashrom:
- # ./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512

-No EEPROM/flash device found.
