===== Q: I sporadically receive timeouts from the iol-master-appl =====

The timeouts usually look like this:
<code>
[16:37:36 WARN ] iolink_dl_handle_error: Reception timeout: 9f    
</code>
followed by a reconnect or connection loss.

===== A: Raise the realtime level of the iol-master-appl =====

The issue comes from too low priority for the communication between the stack (''iol-master-appl'') and the ''MAX14819''. 

To raise the realtime level, you need to set the parameter ''-i'', allow ''cpuisol'' on your device, and run the ''iol-master-appl'' with ''sudo''. The details are described here: [[..:sw:2_iol-master-application:2.2_command-line-timing|Command Line Timing]].
