Preparation steps
- Obtain a Linux PC workstation with a serial communication port and a micro SD card reader.
- Download the 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 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 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 uImage-cm-t3730.bin to the micro SD card first (FAT) partition and name it uImage-cm-t3730.
- Format the third micro SD card partition with EXT3 filesystem.
- Extract the content of 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.

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.
|
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.
