### INSTRUCTIONS FOR SETTING UP THE NIGHTLY BUILDS ###

-	Go to the RedPitaya/downloads page and download the latest Linux OS image: https://downloads.redpitaya.com/downloads/LinuxOS/
-	Write the Linux OS to the SD card using the BalenaEtcher
-	Extract the Ecosystem from the ".zip" directly onto the SD card (if possible without extracting it to a folder on a computer first)


## WINDOWS only ##

If you are using Windows, please read the following section carefully. Linux and MacOS are not affected by this.

This issue is connected to case sensitivity. Linux and MacOS are case-sensitive. Therefore, files like "example.txt" and "EXAMPLE.txt"
are treated as two different files. Windows, on the other hand, is case-insensitive. Consequently, the previously mentioned files are
treated as the same file.

As Red Pitaya is working on a Linux OS, sixteen files that are a part of the Linux OS have the same name, but one in a pair is written 
in capital letters and the other in lowercase. When extracting the ecosystem on Windows, only one file out of the pair can be kept.

-	When asked whether to overwrite a file or not, the extraction tool,
    select the following options (depending on the byte size of files):

+--------------+------------------+
|  File name   |  File byte size  |
+==============+==================+
|  connmark    |  901             |
|  xt_dscp     |  697             |
|  xt_mark     |  184             |
|  xt_rateest  |  859             |
|  xt_tcpmss   |  235             |
|  ipt_ecn     |  901             |
|  ipt_ttl     |  375             |
|  ip6t_hl     |  408             |
+--------------+------------------+
    * The file names are not exactly the same. Please use the file size to decide whether to overwrite the file or not.

The general rule:
-   Always take the smaller file, except when the difference in size is bigger than 200 bytes
    (for example, if prompted to choose between file sizes 199 bytes and 901 bytes, choose 901.
    If the selection is between 235 and 253 bytes, choose 235 (the lower size)).

The same happens when extracting the ecosystem to a folder on a computer first and then copying it to the SD card.
The difference is that Windows might automatically perform the overwrite without any notifications.

If the files are not overwritten correctly, you will not be able to establish a connection with the Red Pitaya.


There might be other file combinations that work; this is a combination that is working for us.
