Posted by roboard On 07 / 06 / 2015 0 Comment

This document provides information showing how to install DuinOS using Mac OS X. For more information about DuinOS and its usage, refer to the here.

Download the latest DuinOS and unzip to the root folder. The unzipped DuinOS.img file should be about 1 GB.

In step 2, we will go over the process to copy DuinOS onto the MicroSD card.

Insert a blank MicroSD flash storage card to an USB-to-MicroSD adapter and insert the adapter to your computer.

After the MicroSD card is detected and recognized, an icon similar to the following shows up on desktop.

Next, launch a terminal window.

From the terminal window, execute the following command:

diskutil list

You can see a list of storage devices, similar to the following screen:

From the list of storage devices, identify the one associates with the MicroSD card.

For the example in this application note, /dev/disk1 is the MicroSD card.

Make note of the storage device name and partition identifier associate with the MicroSD card.

For the example in this application note, the partition identifier is disk1s1.

Next, we need to remove the MicroSD card partition with the following command:

diskutil umount /dev/disk1s1

(If the MicroSD card you are using has been configured with multiple partitions, repeat the above for each partition.)

After MicroSD partition is removed, we can see the confirmation as shown in the following screen.

At the same time, the icon represting the MicroSD partition also disappears from the desktop.

Then, execute the following command to place DuinOS onto the MicroSD card:

dd of={MicroSD device ID} if={DuinOS image file name} bs=1m

For the example in this application note, the command is as follow:
dd of=/dev/disk1 if=/DuinOS.img bs=1m

Be patient, it takes 6 ~ 7 minutes or longer to complete the task, depending the the MicroSD card’s read/write speed.

After the process is completed, remove the USB-to-MicroSD adapter from the computer and remove the MicroSD card from the adapter.

Next, we will use the configured MicroSD card as the boot storage for an 86Duino board.

Insert the MicroSD configured with DuinOS from the earlier steps into the MicroSD slot on the 86Duino board and apply power.

During startup, when the MicroSD card with DuinOS is detected, the 86Duino board will boot from the MicroSD card instead of its internal flash.
