== Preparation steps ==
* Obtain a Linux PC workstation with a serial communication port and a micro SD card reader.
* Download the [http://www.compulab.co.il/t3730/download/t3730-linux.zip Linux package for CM-T3730] from CompuLab website. Unzip the package to a directory on your host workstation.
* All image files mentioned below can be found in {{filename|images}} subdirectory.
* The micro SD card, supplied with the CM-T3730 Evaluation kit, has already been pre-partitioned as described in [[CM-T3x: U-Boot: Firmware Overview#Default MMC/SD card mapping|CM-T3x: U-Boot: Firmware Overview]] article.

== Image installation ==
* Plug the micro SD card, supplied with CM-T3730 Evaluation kit, into the micro SD card reader attached to your desktop workstation.
* Copy the {{filename|uImage-cm-t3730.bin}} to the micro SD card first (FAT) partition and name it {{filename|uImage-cm-t3730}}.
* Format the third micro SD card partition with EXT3 filesystem.
* Extract the content of {{filename|Angstrom-image.tar.bz2}} onto that partition.
* Remove the micro SD card from the SD card reader and install it in the CM-T3730 micro SD card socket (P5).

== Starting the CM-T3730 ==
* Connect the host PC to the SB-T35 base-board (connector P12) via the serial cable supplied with the evaluation kit.
* Start terminal emulation software on your PC. Set baud rate to 115200 bps, 8 bit per frame, 1 stop bit, no parity, no flow control.
* Turn on the CM-T3730 evaluation system. The U-Boot boot-loader will start and load the Linux kernel.
{{Note|If you want to get back to U-Boot prompt, hold '''Ctrl-C''' during reset.}}
CM-T3730 will boot Angstrom Linux from the micro SD card. Note, that the first boot takes a long time because Angstrom Linux performs a lot of one-time initialization tasks.
{{Important|When the Angstrom Linux is run for the first time it presents several configuration screens. Make sure to choose "Angstrom" profile in the profile selection.}}

== Troubleshooting ==
* CM-T3730 does not load Angstrom Linux:
** Check that you followed all the above steps closely.
** Power on the CM-T3730 while holding '''Ctrl-C'''.
** In U-Boot command prompt, restore the default environment:<pre>CM-T3730 # env default -f</pre>
** Save the environment onto the micro SD card:<pre>CM-T3730 # saveenv</pre>
** Reset the CM-T3730 (SW2 on SB-T35)
