Raspberry Pi question.
I ported a working notebook from my computer to RPi where Mathematica was pre-installed. It starts nicely, but stops as it tries to read a simple text file. The very first lines are these:
$HomeDirectory
/home/pi
dict0 = ToString /@ ReadList["sv_JSPFirefoxRensadCRUTF-8.txt"]
ReadList::noopen: Cannot open sv_JSPFirefoxRensadCRUTF-8.txt.
$Failed
I have also contacted the Wolfram community, a lot of readers, no answer. I am turning into desperation mode.
I have not changed anything, same text file etc. Any suggestions would be much appreciated. Thank you very much in advance.

Just an idea: what happens if you give full path to the same file?

YES! Thank you, very much. So simple, I blush. I do not understand, the directory is set to the folder. Now I get some problems further down the notebook, I will deal with those tomorrow (getting late here). Thank you very much!

$HomeDirectory returns your home directory but does not set your working directory to that directory. DirectoryStack shows you what directories have been set. $Path is also useful here. You need to use SetDirectory.
SetDirectory[]
or
SetDirectory[$HomeDirectory]
You should see the Directories & Directory Operations guide for more information.
Hope this helps.
