Hi,

I would like to understand that the file system partiotion of WP76XX.  
For example, “/sys” is ROM or RAM.

I read “AirPrime\_WP76xx\_Product\_Technical\_Specification\_Rev11\_0.pdf”, but I could not solve it.

Do you know any documents or information about it?

normally i will use “mount” and “df -h” to check.  
I only know the tmpfs is the RAM area, but not quite sure about /sys.
