Keep in mind that with some updates it is only necessary to replace the ospi.py Python file and it is not necessary to backup and restore the config files.
In other updates there have been changes to various other files and it is best to do a full re-install. This will likely be the case when the parallel/sequential option is added.
I just discovered that it is easy to auto detect the Pi board rev and have implemented code to set the GPIO pin configuration automatically. This eliminates the need to manually edit the code tor use with Rev 1 boards.
