== Preparation steps ==
{{Note|It is possible to install Linux on CM-A510 using either an NFS share, USB flash drive or a SATA hard drive. The NFS method is recommended because NFS setup will ease further Linux evaluation and development.}}
* Obtain a PC workstation with serial communication port.
* For installation using NFS install TFTP server on host PC. For Windows machines we recommend [http://tftpd32.jounin.net/ TFTPD32] included in this distribution package.
* Download the [http://www.compulab.co.il/x300/download/x300-linux.zip Linux distribution package for CM-A510] from CompuLab's website . Unzip the package to a directory on your host workstation.
* All image files mentioned below can be found in {{filename|images}} subdirectory
* Copy {{filename|debian-image.ubi}} and {{filename|kernel.img}} from [http://www.compulab.co.il/x300/download/x300-linux.zip Linux distribution package for CM-A510] either to a directory exported through NFS or to a USB flash drive.

== Image installation ==
* Connect the host PC to the CM-A510 via the serial cable supplied with the CM-A510 evaluation kit.
* Start terminal emulation software on your PC using the COM port to which the serial cable is connected. Set baud rate to 115200 bps, 8 bit per frame, 1 stop bit, no parity, no flow control.
* Turn on the CM-A510. The U-Boot boot-loader will start and you will get a command prompt.
*: {{Note|If the boot settings of your CM-A510 are different than default, you may need to press and hold ^C while turning on the CM-A510, in order to get command prompt.}}

=== Installation using NFS ===
* Connect CM-A510 LAN0 Ethernet port (connector P11 on SB-A510) to your local Ethernet
* Make sure that Linux kernel binary image {{filename|kernel.img}}, ramdisk image {{filename|ramdisk.img}} and bootloader script image {{filename|bootscr.img}} are accessible by the TFTP server.
*: - On Windows machine: copy {{filename|kernel.img}}, {{filename|ramdisk.img}} and {{filename|bootscr.img}} to the same folder and point the TFTP server to that folder
*: - On Linux machine: copy {{filename|kernel.img}}, {{filename|ramdisk.img}} and {{filename|bootscr.img}} to TFTP sevrver root directory, usually {{filename|/tftpboot}} or {{filename|/tftproot}}.
* You can use U-boot {{cmd|dhcp}} command to obtain IP address or manually set the {{parameter|ipaddr}} environment variable:
<pre>
> setenv ipaddr <CM-A510 ip address>
</pre>
* Set the {{parameter|serverip}} environment variable and save the new environment to NAND flash:
<pre>
> setenv serverip <host ip address>
> saveenv
</pre>

* Use the following U-boot command to boot Linux on CM-A510:
<pre>
> tftp 100000 bootscr.img && autoscr 100000
</pre>
* During boot the CM-A510 tries to obtain an IP address using DHCP. If you do not have DHCP server you can set the CM-A510 IP address statically using {{cmd|ifconfig}}:
<pre>
$ ifconfig eth0 <ip address>
</pre>
* After the ramdisk image is loaded you will get Linux login prompt. Login as {{parameter|root}} into the system.
* Mount the NFS share containing {{filename|kernel.img}} and {{filename|debian-image.ubi}} image:
<pre>
$ mount <host ip>:/path/to/nfs/share /mnt/net
</pre>
* Format the NAND flash kernel partition and write the kernel image onto it:
<pre>
$ flash_eraseall /dev/mtd0
$ nandwrite -p /dev/mtd0 /mnt/net/kernel.img
</pre>
* Format the NAND flash root filesystem partition and write Debian filesystem image onto it:
<pre>
$ ubiformat /dev/mtd1 -f /mnt/net/debian-image.ubi
</pre>

=== Installation using USB flash drive ===
* Make sure that CM-A510 LAN0 Ethernet port (connector P11 on SB-A510) is '''disconnected'''
* Make sure that Linux kernel binary image {{filename|kernel.img}}, ramdisk image {{filename|ramdisk.img}}, Debian filesystem UBI image {{filename|debian-image.ubi}} and bootloader script image {{filename|bootscr.img}} are present at the root directory of the USB flash drive.
* Connect USB flash drive to SB-A510. Use USB1 port (the lower USB connector of P11 on SB-A510).
* Use the following U-boot command to boot Linux on CM-A510:
<pre>
> usb start
> fatload usb 0:1 100000 bootscr.img
> autoscr 100000
</pre>
* After the ramdisk image is loaded you will get Linux login prompt. Login as {{parameter|root}} into the system.
* The USB flash drive will be automatically mounted under {{filename|/media/sda1}}
* Format the NAND flash kernel partition and write the kernel image onto it:
<pre>
$ flash_eraseall /dev/mtd0
$ nandwrite -p /dev/mtd0 /media/sda1/kernel.img
</pre>
* Format the NAND flash root filesystem partition and write Debian filesystem image onto it:
<pre>
$ ubiformat /dev/mtd1 -f /media/sda1/debian-image.ubi
</pre>

== After Installation ==

<ol>
<li> Reset the CM-A510.</li>
{{Note|If the boot settings of your CM-A510 are different than default, you may need to press and hold ^C while turning the CM-A510 on, in order to get command prompt.}}
<li> To boot Linux, type:
<pre>> setenv bootargs
> nboot 200000 nand0 0; bootm</pre>
{{Caution|The Linux kernel for CM-A510 is shipped with built-in command line parameters that define primary console, default display settings, root device and root filesystem type. Setting U-Boot {{parameter|bootargs}} environment variable overrides default kernel command line!}}
</li>
<li> For Linux automatic boot, type:
<pre>
> setenv bootdelay 3
> setenv bootcmd "nboot 200000 nand0 0; bootm"
> saveenv
> boot
</pre>
{{Note|If you want to get back to U-Boot prompt, hold '''Ctrl-C''' during reset.}}
</li>
</ol>

=== Connection and Logging In ===

Use the following usernames and passwords to login:

Account with administrative privileges:
<pre>
User: root
Password: 111111
</pre>
Regular user account:
<pre>
User: user
Password: 111111
</pre>
In addition to these accounts CM-A510 allows anonymous FTP access.
