=== Q: Where can I found find Naon SOM hardware information? ===

'''A''': please refer to the following pagesresources:* [[Naon_SOM]]* [[Hardware_Manual_(NAON) | Naon Hardware Manual]]* [http://www.dave.eu/dave-cpu-module-am387x-dm814x-naon.html Naon web page on Dave's website]

'''A'''=== Q: yes, we Do you provide the Naon Embedded Linux Kit. Please refer to [[Naon_Embedded_Linux_Kit_(NELK)]]an evaluation kit? ===

* 1x NaonEVB-Mid or NaonEVB-Lite carrier board* 1x Naon CPU module* 1x +12V Power supply adapter* 1x SD Card containing:** Documentation*** Naon, Maya and Dido hardware manuals*** NaonEVBs schematics and mechanical drawings*** Application notes** Software*** Boot partition with bootloader and kernel binaries*** Root file system partition*** [[:Category:DVDK | '''DAVE Embedded Systems''' Virtual Development Kit]]: virtual machine with pre-installed SDK and source trees* 1x packing list = System design = === Q: Can you suggest some guidelines for the carrier board design? === '''A''': As a starting point, you can refer to the [[Carrier_board_design_guidelines_(SOM)]] page, that will highlight some best practices that applies to all SOMs. For specific information on Naon, please refer to the [[Integration_guide_(Naon) | Naon integration guide]]. === Q: What is Naon power consumption? === '''A''': Naon platform is so flexible that is virtually impossible to test for all possible configurations and applications on the market. Generally speaking, application specific requirements have to be taken into consideration in order to size power supply unit and to implement thermal management properly. However, we've performed some tests that should cover most of real-world scenarios and we've reported the results on the [[Power_consumption_(Naon)]] page. === Q: How can I reduce power consumption? === '''A''': The Linux kernel provided with the NELK implements some power management features, in particular: * CPU Governor Usage* Operating Performance Points* Subsystem frequency selection* Standby mode For a full description of the power management strategies, please refer to the [[NELK Power Management]] page. === Q: During operation, the CPU is rather hot. Is it normal? Can you suggest some strategies for thermal management? === '''A''': Yes, it is normal. DM814x/AM387x thermal behavior is strictly related to the process (known as “Hi-Performance / Hi-Leakage”) used to produce the die. The manufacturer chose to focus on maximizing the performance, at the expense of power consumption because the component was conceived to penetrate the high-definition video market segment, which is known to be highly demanding in terms of hardware resources. Please refer to the [[Thermal_management_(Naon)]] page for more information on the thermal management strategies.

== = Q: I've received the NELK package. How am I supposed to start working with it? ===

* Check che the kit contentswith the packing list included in the box* If you have the bootable SD cardis available:

** connect the power supply adapter to the main power supply and to the carrier board** connect the serial cable from your pc to the carrier boardas described in [[NaonEVB-Mid#Quick_start_.28NELK.29 | NaonEVB-Mid Quick start]] and [[NaonEVB-Lite#Quick_start_.28NELK.29 | NaonEVB-Lite Quick start]]

* Install the DVDK virtual machine image(please refer to [[VirtualBox_Starting_DVDK_Virtual_Machine | Starting DVDK]])* Check the virtual machine components* Read the (please refer to [[Naon_Embedded_Linux_Kit_(NELK)#NELK_DVDK_Layout | NELK HowTosDVDK layout]])* Build the software components for the Naon platformas described in [[Development_Environment_HowTo_(NELK)#Build_the_whole_kit | NELK: Build the whole kit]]* Boot the system from network to test the development platform(please refer to [[Development_Environment_HowTo_(NELK)#Boot_the_system | Boot the system]]) === Q: How can I update the NELK version? === '''A''': The NELK update procedure, starting from an existing DVDK installation and updating only the SDK (tools, sources and root file system) without creating a full new DVDK virtual machine, is described in the [[How_to_update_NELK]] page.
