Variable Documentation

String SysLink_params

Config params override strings.

This string is a list of semi-colon-delimited "assignments" that can be set by users prior to the initial call to SysLink_setup() to affect system behavior.

Example assignments include:

• "ProcMgr.proc[DSP].mmuEnable=FALSE;"
• "ProcMgr.proc[VPSS-M3].mmuEnable=TRUE;"
• "SharedRegion.entry[1].cacheEnable=FALSE;"
• "SharedRegion.entry[3].cacheEnable=FALSE;"

Remarks:

Note that many users don't explicitly set this string and rebuild their app, but rather leverage the SL_PARAMS environment variable to set this string's value.

In many systems, slaveloader (or similar) is used to load and start the slaves, and is therefore the initial app in the system. In those systems, it's important to set this variable (or SL_PARAMS) prior to running slaveloader.

A common mistake is to forget to terminate the string with a trailing semi-colon.
