This tutorial is mainly intended for those who are building a Zynthian Box using one of the ''official'' kits, that i offer here:
[http://shop.zynthian.org Zynthian Shop]
Specifically, the instructions are for the assembly of kits v1 (version 1), those using the 2in1 circuit and the PiTFT 2.8' display. If you have a newer kit v2, based in the All-In-One circuit and the PiScreen 3.5' display, you better should read [[Building a Zynthian Box using an official Kit v2 | this updated tutorial]].

Anyway, it's quite detailed and can be used as a guide to build a custom Zynthian Box from scratch. Of course, you will have to be creative if you want to do it in that way ;-)

The easiest way of getting the software is downloading the last ''official'' SD image from here:

'''[http://blog.zynthian.org/download/zynthian_gorgona_next_rbpi3_pitft28-2017-11-14.img.torrent Download Zynthian "Gorgona Next" SD-image, configured for Kits v1]'''
It's a 11GB image file (plenty of soundfonts) compiled for RBPi3.
If you prefer a smaller image (Gorgonilla) or need support for RBPi2, then you can download the older Gorgona image:
'''[https://discourse.zynthian.org/t/merry-zynthians-and-happy-new-sd-image/314 Download Zynthian "Gorgona" SD-image]'''
'''[https://discourse.zynthian.org/t/merry-zynthians-and-happy-new-sd-image/314 Download Zynthian "Gorgona" SD-image]'''
These SD images include all the Zynthian software, properly configured for the standard hardware -- ready to use. Plug and play! ;-)
After downloading the SD-image, you have to write it to a SDcard. You need a minimum size of 16GB SDcard for the full ''Gorgona'' image or 8GB for the ''Gorgonilla'' lite image.
Use Etcher https://etcher.io/ (free software works on Mac, Windows or Linux) to flash the image onto the SDcard.
Or do it manually: There is a really good manual for this at [https://www.raspberrypi.org/documentation/installation/installing-images/ this link].
If you prefer, you can build your own SD image following these instructions:

Of course, other arrangements and combinations are possible and some community members are working on them:
Of course, other arrangements and combinations are possible. You can easily configure your hardware using the [http://wiki.zynthian.org/index.php/Configuration_Users_Guide Webconf Tool], or if it doesn't work, tweaking from the [http://wiki.zynthian.org/index.php/Command_Line_User_Guide command line].
You can take a look to some of the alternate builds made by some community members:

For finding and solving problems, i really recommend to connect a HDMI display to the RBPi. It will give you accurate information during the booting sequence. Also, if you connect a USB keyboard, you can login into the system and get extra information, inspect the logs, etc.

If the problem persist it's very probable you haven't solder correctly the side 26-pin connector. You should double check the connector and be sure that it's correctly soldered.

In that case, probably the system is not booting correctly. You could try to connect a HDMI display and see if the system is booting. If you can't see the booting sequence, then you should re-burn your SD-card with the Zynthian image. Also, check that your image file is correct by using the SHA1 signature.

===The display is completely white===
The latest SD Gorgona Edge image is pre-configured for the new v2 Kit. As you are using a Kit v1, you should access the Webconf tool (see [[Configuration_Users_Guide]]) using your browser and change these options:
Display: PiTFT 2.8’ Resistive
Wiring Layout: PROTOTYPE-4
Style -> Font Size: 10
