 ====== Troubleshooting: Application does not start ====== ====== Troubleshooting: Application does not start ======
 +===== Kernel Version =====
 +Did you boot into the right kernel version? Please make sure to follow [[embedded_systems:ethercat:install_acontis_stack|Install the Acontis EtherCAT Stack]] and notes therein.

 +===== Timing problems =====
 +Warning and error messages like these:
  
 +<code>
 +082039 : eUsrJob_ProcessAllRxFrames - not all previously sent frames are received/processed (frame loss)!
 +082039 : No response on cyclic Ethernet frame
 +082039 : DCM Status: ERROR: controller error - synchronisation out of limit (0x981201C2)
 +</code>
 +
 +indicates timing and real-time problems.
 +See [[embedded_systems:ethercat:troubleshooting:timing_problem |Timing problems]] for more information.
 +
 +Add ''-v 3'' to log the EtherCAT jitter.
 +
 +I.e. Start demo:
 +<code>
 +sudo ./EcMasterDemoEval -f <path_to_eni>/ein.xml -i85254x 1 1 -perf -v 3
 +</code>
 +
 +I.e. Output:
 +<code>
 +012080 : Job times during startup <INIT> to <OP>:
 +012080 : ================================================================
 +012080 : PerfMsmt 'JOB_ProcessAllRxFrames' (avg/max) [usec]:    1.6/  5.7

 +This line:\\
 +''012080 : PerfMsmt 'Cycle Time            ' (avg/max) [usec]:  1000.0/10''**30.2**\\
 +indicates a maximal jitter of 30.2nsec which is a small jitter.
