(NOTE)
*2) JFFS2 file system is not a block device and thus swap cannot be created on the file system.
*3) DTM (DaTa Manager) is a set of modules that provide database functions to the applications. User applications can
utilize the SL data manager class to easily implement store, sort, and search data entities. Applications that utilize the
XML file format for the SL-5500 PIM information can also run on the SL-5600. However, all of the default PIM
applications on the SL-5600 now adopt and are managed by the DTM (PIM database). Thus, any 3
rd
party PIM
applications that access the XML files of the SL-5500 PIM applications will not run as expected. Developers need to
incorporate the DTM access for those PIM applications.
*4) Processes are executed with user privileges, and thus some directories may not be accessed depending on the
permissions granted. User applications must be executed with root privilege if the application will have access to the
directories at which only root privileges are granted. See section 3 and Appendix A for the details of the SL-5600
directories from “/”.
