=== DIVELK microSD Layout ===

The microSD card provided with DIVELK is partitioned as shown in the following image:

[[File:DIVELK-uSD-partitioning.png|thumb|center|300px|microSD card partitioning]]

Most of storage space is occupied by two partitions:

*a <code>FAT32</code> partition (<code>mmcblk0p1</code>) containing:

**U-Boot <code>bootscript</code>

**Linux kernel and DTB binary images

**DIVELK virtual machine image in OFV format ([[Managed_Virtual_Machine_(MVM)|MVM]] basic version)

**7-zip Windows executable file

*an <code>ext3</code> partition (<code>mmcblk0p2</code>) containing the root file system for the target.

<code>bootscript</code> and root file system are used to boot the target as described in [[#Target_setup_and_first_boot|this section]].

It is worth remembering that the microSD card is bootable, because U-Boot image files ('''MLO''' and '''u-boot.img''') and kernel image ('''uImage''') are present into first FAT32 partition: filename '''MUST''' be the one written before.

However, even if U-Boot is run from the microSD card, '''the environment is retrieved from NOR flash'''.

====How to create a bootable microSD card====

For creating a bootable microSD card, simply follows the following steps:

* create two partition: first partition FAT32 and a second partition ext3

* mark as "bootable" the first partition (using for example <code>gparted</code> on VM)

* copy MLO, u-boot.img and boot.scr on FAT32 partition

** copy kernel and dtb on the same partition

** all files can be retrieved from [[Diva_Embedded_Linux_Kit_(DIVELK)#Downloadable_binary_images|here]]

* extract rfs on ext3 partition

Alternatively, it is also possible to create a bootable sd using this script:

<pre>

#!/bin/bash

if [[ -z $1 || -z $2 || -z $3 ]]

then

echo "$0 Usage:"

echo " $0 <device> <binaries directory> <rootfs tar.bz2>"

echo " Example: $0 /dev/sdc binaries/ rootfs.tar.bz2"

exit

fi

if [ "$(whoami)" != "root" ]

then

echo "you must be root to run this script!"

exit

fi

if ! [[ -b $1 ]]

then

echo "$1 is not a valid block device!"

exit

fi

if ! [[ -d $2 ]]

then

echo "Incorrect Binaries location!"

exit

fi

if ! [[ -f $3 ]]

then

echo "Incorrect rootfs location!"

exit

fi

DRIVE=$1

if [[ "$DRIVE" == *"mmcblk"* ]]

then

echo "You're using a mmc device, I need to fix partition names"

PART="p"

else

PART=""

fi

BINARIES=$2

RFS=$3

echo "All data on "$DRIVE" now will be destroyed! Continue? [y/n]"

read ans

if ! [ $ans == 'y' ]

then

exit

fi

echo "[Partitioning $1...]"

dd if=/dev/zero of=$DRIVE bs=1024 count=1024

SIZE=`fdisk -l $DRIVE | grep Disk | awk '{print $5}'`

echo DISK SIZE - $SIZE bytes

CYLINDERS=`echo $SIZE/255/63/512 | bc`

# check if we're running an old (e.g. 2.20.x) or new (e.g. 2.24.x) sfdisk

sfdisk --help | grep -- -H

if [ "$?" -eq "0" ]

then

{

echo 10,1380,0x0c,*

echo 1390,,83,-

} | sfdisk -D -H 255 -S 63 -C $CYLINDERS $DRIVE

else

{

echo 10,4086M,0x0c,*

echo 4096M,,83,-

} | sfdisk $DRIVE

fi

partprobe

echo "[Making filesystems...]"

mkfs.vfat -F 32 -n BOOT "$DRIVE$PART"1 #> /dev/null

mkfs.ext3 -L ROOTFS "$DRIVE$PART"2 #> /dev/null

echo "[Copying files...]"

binaries_dir=${BINARIES%/}

mount "$DRIVE$PART"1 /mnt

cp -av --no-preserve=ownership $binaries_dir/* /mnt/

umount "$DRIVE$PART"1

echo "[Extracting rfs (this may take a while...)]"

mount "$DRIVE$PART"2 /mnt

tar jxf $RFS -C /mnt > /dev/null

chmod 755 /mnt

umount "$DRIVE$PART"2

echo "[Done]"

</pre>

To use this script, simply copy its content to a mksd.sh file.

Then, run:

<pre>

chmod a+x mksd.sh

</pre>

to give executable permissions to the file.

Once this has been done, insert a 16gb microsd card and run:

<pre>

./mksd /dev/sdX binaries-folder rootfs.tar.bz2

</pre>

The script will partition the sd card and copy the binaries and rootfs to the correct partition on the sd card.

The operation will take few minutes.

===Target setup and first boot===

This section describes how to quick start DIVA board delivered along with DIVELK kit:

*connect the ~~provided TTL/~~DB9 serial cable adapter to ~~J24~~ J25 pin-strip connector on DACU ~~connector~~ as shown on picture below*insert microSD card in the DACU slot J34*optionally connect the system to Ethernet LAN by plugging cable into connector J7

*on host side start your favorite terminal that will be used to interact with the target's serial console; communication parameters are 115200-8-N-1

*optionally connect the system to Ethernet LAN by plugging cable into connector J16

*connect the provided 12V power supply to JP2 DACU connector

*insert microSD card in the DACU slot J34

{{ImportantMessage|text=Either version of MVM is installed, it provides the tools required to build [[Building_U-Boot_(DIVELK)|U-boot]] and [[Building_Linux_kernel_(DIVELK)|Linux kernel]]. It does not include the tools required to run Yocto build system instead.}}

DIVELK MVM can be downloaded [https://cloud.dave.eu/ws-reserved-area-divelk/DIVELK-3.0.0 here]. For accessing DIVELK Reserved area please contact our [mailto:sales@dave.eu sales department]

===Target configuration for the development stage (<code>net_nfs</code>)===

{{ImportantMessage|text=The default DIVELK Virtual Machine network configuration is using NAT: this allows to accessing external network (i.e. Internet) using the host computer's networking connection.

For software development using <code>net_nfs</code> with tftp/nfs protocols, please configure your VM network interface in ''Bridge mode'' (see below)}}

During the development stage, the target is usually connected via Ethernet LAN to the host machine and is configured to:

*retrieve binary images (i.e. Linux kernel) via TFTP protocol

*mount the development root file system via NFS protocol. This root file system is physically in the file system of the host machine as depicted [[Deploying_Embedded_Linux_Systems#The_development_environment|here]].An example of ''Bridge mode'' configuration for DIVELK can be found [[Booting_the_system_via_NFS_(DIVELK) | here]]

In DAVE Embedded Systems development kits, this configuration is generally denoted as <code>net_nfs</code>. U-Boot bootloader supports this configuration. Some U-Boot environment variables are needed to set it up. They are detailed [[Booting_Linux_Kernel#Configuration_net_nfs|here]].

For more details about TFTP and NFS servers on host side, please refer to this [[Setting_up_tftp_and_nfs|page]].

===Target configuration for standalone boot===

Please refer to [[Standalone_boot_(DIVELK)|this page]].

===Developing the software for the target===

Please refer to [[Developing the software for the target (DIVELK)|this page]].

==Advanced topics==

===Debugging with Eclipse===
