Linux system porting for Beaglebone Development Board

I am the first contact with embedded system porting, say my learning process.
Baidu has a lot of beaglebone information about the Beaglebone parameters, cross-compiler tool chain, as well as the buildroot system porting and other information.
This buildroot system is really ... I do not know how to describe the download took a long time, but learned a lot.
In fact, Beaglebone is very convenient, the system is all in the microSD card, unplugged many times.
It took two or three weeks to learn about the basics of Baidu and learning the information above.
Of course, the last transplant system must not use BuildRoot, or use Ubuntu convenient point.
Attach the ubuntu14.04 SD card image below:
Https://rcn-ee.net/rootfs/2015-01-06/ubuntu-14.04.1-console-armhf-2015-01-06.tar.xz

Open the Vmwware virtual machine, enter the 32-bit ubutnu14.04 system, and pull the image downloaded above.
(Do not install the virtual machine self-Baidu, remember in the virtual machine Ubuntu installed Vmware-tools, otherwise the mouse, mobile files and other operations inconvenient)

Here is the command to burn the image:

Tar XF ubuntu-14.04.1-console-armhf-2015-01-06.tar.xz

CD ubuntu-14.04.1-console-armhf-2015-01-06

sudo./setup_sdcard.sh--mmc/dev/sdx--DTB Beaglebone
The SDX here refers to your microsdcard, which can be viewed with the fdisk-l command.


After inserting the SD card into the Beaglebone, switch to the virtual machine interface and insert the Beaglebone USB.
Enter Ls/dev to see which is your USB, typically ttyUSB0
Switch to root permissions input minicom–s configuration minicom

+-----[Configuration]------+            | Filenames and Paths      |            | File Transfer Protocols  |            | Serial Port Setup        |            | Modem and dialing        |            | Screen and keyboard      |            | Save setup as DFL        |            | Save setup as ...          |            | Exit                     |            | Exit from Minicom        |            +--------------------------+
Choose to enter serial port setup and configure it according to the information previously viewed (Baidu steals a picture below)


Be sure to turn off the F option (Hardware Flow Control) or you will not be able to connect.
Note: Each option is selected according to A-g, and the operation is very special.
The last enter key, select Save Setup as DFL to be saved as the default configuration.
After exiting, enter minicom to see the Beaglebone shell interface.
