Deploy GyroidOS on TQ-Systems TQMa8MPxL-MBa8MPxL

This section describes how to deploy GyroidOS on the TQ-Systems TQMa8MPxL module when mounted on the MBa8MPxL board.

GyroidOS image

Build the GyroidOS image according to the instructions here.

Note: In order to build the image, you need to accept the Freescale EULA by placing the line ACCEPT_FSL_EULA = "1" in out-yocto/conf/local.conf.

Create bootable medium

Requirements

  • A successfully built GyroidOS image file trustmeimage.img.
  • The script copy_image_to_disk_mbr.sh which can be found on GitHub or in your build folder at trustme/build/yocto/copy_image_to_disk.sh
  • A MicroSD card compatible with your board
  • Optional: Bmap file trustmeimage.img.bmap which is automatically created by the build system and deployed next to trustmeimage.img. This enables flashing using bmaptool.

First, ensure the needed packages are installed on your system.

apt-get install util-linux btrfs-progs sgdisk parted bmap-tools

Copy GyroidOS image to disk

Now the GyroidOS image can be copied to the MicroSD card. The provided script takes care of expanding the partitions to use all of the available disk space.

WARNING: This operation will wipe all data on the target device

sudo copy_image_to_disk_mbr.sh <gyroidos-image> </path/to/target/device>

If you have built from source in ws-yocto and your target device is /dev/mmcblk0 the command would be:

cd ws-yocto # your yocto workspace directory
sudo copy_image_to_disk_mbr.sh \
	out-yocto/tmp/deploy/images/tqma8mpxl-mba8mpxl/trustme_image/trustmeimage.img \
	/dev/mmcblk0

In this example, if the bmap file out-yocto/tmp/deploy/images/tqma8mpxl-mba8mpxl/trustme_image/trustmeimage.img.bmap exists and bmaptool is installed, the script will automatically flash to the MicroSD card using the quick bmaptool. If one of these requirements is not fulfilled copy_image_to_disk_mbr.sh will fall back to slower copy using dd.

Boot GyroidOS

Connect your PC via a Micro-USB cable to connector X28 on the board. This will create four serial interfaces, e.g.:

crw-rw---- 1 0 986 188, 0 19. Feb 11:32 /dev/ttyUSB0
crw-rw---- 1 0 986 188, 1 19. Feb 11:32 /dev/ttyUSB1
crw-rw---- 1 0 986 188, 2 19. Feb 11:32 /dev/ttyUSB2
crw-rw---- 1 0 986 188, 3 19. Feb 11:32 /dev/ttyUSB3

Connect to the CML debug shell via the highest interface, e.g. ttyUSB3.
