23.3.1.2RAM-Disk Storage Locations

Caution: Files in this location are stored in RAM, and will be lost during CMM reboots.

Due to the constraints of writing to flash memory, larger file operations such as decompressing an archive should be performed on RAM-disk in the following directory:

/usr/local/cmm/temp - Useful for storing temporary files. Applications should make a subdirectory for use with their temporary files. Do not add more than 5 Mbytes to this location.

23.3.2RAM Constraints

Up to 32 Mbytes of RAM are available for use by user applications. RAM usage at runtime, on average, should not exceed this quantity.

23.3.3Interrupt Constraints

User applications should not make use of interrupts. All interrupts are reserved for use by the CMM firmware.

23.4Ram Disk Directory Structure

The following directories are stored on a RAM-disk. These directories store information critical to the CMM and are size constrained. These directories should not be modified in any way.

/usr – Executables including the CMM executables (/usr/local/cmm/bin). Also contains some libraries and temp files.

/lib - Shared library files and drivers

/bin – Linux binary files like ping, mount

/dev – Device driver files

/proc – Special linux area that contains info about memory, drivers, etc.

/root – Empty root user area.

/sbin – Binary files like ifconfig, route

/tmp – Empty

/var – Temp location for log files and other temp files.
