Technically all JTAG-adapter listed by OpenOCD should work, but DH electronics recommends the Olimex Arm-USB-OCD-Tiny-H.
All tests and Documents were made in use of this one.

== Installation ==
This installation was made on the [[Virtual Machine for Application Development]].
All console expressions refer to this Debian system.
# '''OpenOCD'''
#* OpenOCD is a Linux package and is as easy to install as <code>sudo apt-get install openocd</code>
# '''Drivers'''
#* If you use the JTAG-Adapter recommended by DH, then you need to install the FTDI-Drivers as followed:
#**Go to http://www.ftdichip.com/Drivers/D2XX.htm and Download your suitable Driver (32-bit or 64-bit)
#**Navigate into the Download folder <code>cd /home/devel/Downloads</code>
#**Untar the Downloaded zip-file <code>tar xfvz libftd2xx-x86_64-1.4.6.tgz</code>
#**For the next steps you need Admin rights (standard password for the VM is devel): <code>$ sudo –su</code>
#**You need to copy the folder <code>cp libftd2xx.* /usr/local/lib</code>
#**Changing the permission <code>chmod 0755 /usr/local/lib/libftd2xx.so.1.4.6</code>
#** Creating a link <code>ln –sf /usr/local/lib/libftd2xx.so.1.4.6 /usr/local/lib/libftd2xx.so</code>
#** Finish the installation <code>exit</code>

== uBoot Programing ==
There are two ways for doing this.
The easy way is an automatic Bash-script, which handles all the commands needed for the programing process.
In this case you need a specified folder-structure so that the automatic script can find all its needed files.
The other one is to type in the required commands. In a few cases this fails then you need to go the other way
and program the uBoot manually.
# '''Download the needed files here:'''
# '''Download newest uBoot here:''' [https://wiki.dh-electronics.com/index.php?title=COM_iMX6-D2#Downloads uBoot_iMX6]
# '''Automatic Script'''
#*The needed folder structure looks like this:
#**DHcom_uBoot_Programmer
#***bin_File (here are the uBoot files)
#***uBoot_Programmer (here are the Programing scripts)
#**Paste the '''"dhcom_olimex_arm_usb_tiny_h.cfg"'''-file in the OpenOCD folder at <code>/usr/share/openocd/scripts/board</code>
#**The "uBoot_Programmer_Olimex_arm_usb_tiny_h"-file needs to be in the uBoot_Programmer folder
#**The two u-boot files ('''"u-boot-spl-prog"''' and '''"u-boot-with-spl"''') belong to the bin_File folder
#**The '''"u-boot-with-spl"'''-file can be changed with your own uboot-file. You just have to name it like this else it wouldn't be recognized by the script.
#*Open a terminal and navigate into the folder e.g. <code>cd DHcom_uBoot_Programmer/uBoot_Programmer</code>
#*Start the programing script: <code>./uBoot_Programmer_Olimex_arm_usb_tiny_h</code>
# '''Manual Programing'''
#*You need two terminals, one for GDB the other for OpenOCD an da Com-Port to get the serial output
## '''OpenOCD'''
##*<code>openocd –f board/dhcom_olimex_arm_usb_tiny_h.cfg</code>
##*[[File:Openocd.png]]
##*If OpenOCD does not open like in the picture then close and open it again
## '''GDB'''
##*<code>gdb --quiet</code>
##*<code>target remote localhost:3333</code>
##*<code>mon load_image /path/to/the/u-boot-spl-prog/file 0x908000</code>
##*<code>mon reg pc 0x908000</code>
##*<code>mon resume</code>
##*Wait until the message "Searching for IVT header at DDR address 0x18000000" is on the serial output
##*<code>mon halt</code>
##*<code>mon load_image /path/to/the/u-boot-with-spl/file 0x18000000</code>
##*<code>mon resume</code>
