Flash and Compact Flash can be used for both the application program and data storage, but SDRAM is only used for the application program. Appendix B in the user’s manual mentions that 26 MB of storage space is for the users file system (JFFS2). However, after installing the system, it might occupy about 30% of the storage space. For this reason, about 17 MB of space will be available In addition, the df command will be useful. For a system that is running, information about the partitions can be displayed using the df command (which stands for disk full). In Linux, df is the GNU version, and supports the -h, or human readable option, which greatly improves readability.
