This is the minimal buildroot support for the Congatec QMX6 Qseven CoM
|
||||
|
||||
conga-QMX6 is based on the freescale iMX6 SoC. For more information please
|
||||
have a look at http://www.congatec.com/products/qseven/conga-qmx6.html
|
||||
|
||||
The configuration is based on the currently latest kernel release from
|
||||
Congatec's git repository which is based on 3.0.35. The bootloader u-boot
|
||||
is preconfigured on the CPU module and does not need to be replaced.
|
||||
|
||||
To build the default configuration you only have to:
|
||||
|
||||
make qmx6_defconfig && make
|
||||
|
||||
You will need a microSD card of sufficient size and the first or only
|
||||
partition configured as Linux type.
|
||||
|
||||
To transfer the system to the card do:
|
||||
|
||||
$ sudo dd if=output/images/rootfs.ext2 of=/dev/sdX1
|
||||
|
||||
You can optionally extend the filesystem size to the whole partition:
|
||||
|
||||
$ sudo resize2fs /dev/sdX1
|
||||
|
||||
You can also update the card image without completely rewriting it:
|
||||
|
||||
$ sudo mount /dev/sdX1 /mnt
|
||||
$ sudo tar xf output/images/rootfs.tar -C /mnt
|
||||
$ sudo umount /mnt
|
||||
|
||||
Connect a terminal program to the rs232 connector marked "CONSOLE"
|
||||
with baudrate set to 115200, insert the microSD card into the socket
|
||||
on the CPU module and power the board to watch the system boot.
|
||||
|
||||
Booting from the SD card slot on the base board is currently not
|
||||
supported.
