 ====== 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.
 +
 +===== Wrong device instance =====
 +==== Output ====
 +<code>
 +003019 : PCI: device 00:19.0 found
 +003019 : *I8254x-EcLinkOpen() GetPciInfo failed (card not found in registry, 2. instance missing?)
 +003019 : CEcDeviceBase::Open() Failed to open link layer!
 +</code>
 +
 +==== Problem ====
 +The wrong device ID was selected.
 +
 +==== Solution ====
 +Change the device ID.
 +
 +E.g.:
 +Change
 +<code>
 +sudo ./EcMasterDemoEval -f ../../../../eni/06_ENI_2Elmo_1000ms.xml -i8254x 2 1 -perf
 +</code>
 +to
 +<code>
 +sudo ./EcMasterDemoEval -f ../../../../eni/06_ENI_2Elmo_1000ms.xml -i8254x 1 1 -perf
 +</code>
 +
 +===== Bus configuration mismatch =====
 +==== Output ====
 +<code>
 +007270 : Cannot start set master state to INIT (Result = Bus configuration mismatch (0x9811001e))
 +</code>
 +
 +==== Problem ====
 +The network description in the ENI file does not match the connected EtherCAT network.
 +
 +This can be due different reasons:
 +  * Wrong ENI file selected
 +  * Not all slaves are connected
 +  * Not all slaves are powered
 +
 +If the problem occurs irregularly, then there is probably a hardware problem:
 +  * Bad EtherCAT connection between slaves
 +  * Short-term power loss due insufficient power supply (the slave may be booting while the master attempts to connect
 +
 +
 +===== 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
 +012080 : PerfMsmt 'JOB_SendAllCycFrames  ' (avg/max) [usec]:    5.4/  8.5
 +012080 : PerfMsmt 'JOB_MasterTimer       ' (avg/max) [usec]:    1.3/ 10.9
 +012080 : PerfMsmt 'JOB_SendAcycFrames    ' (avg/max) [usec]:    2.4/ 15.7
 +012080 : PerfMsmt 'Cycle Time            ' (avg/max) [usec]:  1000.0/1030.2
 +012080 : PerfMsmt 'myAppWorkPd           ' (avg/max) [usec]:    0.0/  0.4
 +</code>
 +
 +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.
