The update for the pdf reader works only if the files
are decompressed in root of the internal flash.
That is because the content of the installer is:
cp /media/flash/libonyx_ui.so /opt/onyx/arm/lib/
cp /media/flash/onyx_pdf_reader /opt/onyx/arm/bin/
I would suggest that the installer of the future patches
be modifided to something like:
cd `dirname $0`
cp libonyx_ui.so /opt/onyx/arm/lib/
cp onyx_pdf_reader /opt/onyx/arm/bin/
In this way, the files could be decompressed anywhere
(including the SD).
