====== Troubleshooting: | ====== Troubleshooting: | ||
+ | ===== Kernel Version ===== | ||
+ | Did you boot into the right kernel version? Please make sure to follow [[embedded_systems: | ||
+ | |||
+ | ===== Wrong device instance ===== | ||
+ | ==== Output ==== | ||
+ | < | ||
+ | 003019 : PCI: device 00:19.0 found | ||
+ | 003019 : *I8254x-EcLinkOpen() GetPciInfo failed (card not found in registry, 2. instance missing?) | ||
+ | 003019 : CEcDeviceBase:: | ||
+ | </ | ||
+ | |||
+ | ==== Problem ==== | ||
+ | The wrong device ID was selected. | ||
+ | |||
+ | ==== Solution ==== | ||
+ | Change the device ID. | ||
+ | |||
+ | E.g.: | ||
+ | Change | ||
+ | < | ||
+ | sudo ./ | ||
+ | </ | ||
+ | to | ||
+ | < | ||
+ | sudo ./ | ||
+ | </ | ||
+ | |||
+ | ===== Bus configuration mismatch ===== | ||
+ | ==== Output ==== | ||
+ | < | ||
+ | 007270 : Cannot start set master state to INIT (Result = Bus configuration mismatch (0x9811001e)) | ||
+ | </ | ||
+ | |||
+ | ==== 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, | ||
+ | * 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: | ||
+ | |||
+ | < | ||
+ | 082039 : eUsrJob_ProcessAllRxFrames - not all previously sent frames are received/ | ||
+ | 082039 : No response on cyclic Ethernet frame | ||
+ | 082039 : DCM Status: ERROR: controller error - synchronisation out of limit (0x981201C2) | ||
+ | </ | ||
+ | |||
+ | indicates timing and real-time problems. | ||
+ | See [[embedded_systems: | ||
+ | |||
+ | Add '' | ||
+ | |||
+ | I.e. Start demo: | ||
+ | < | ||
+ | sudo ./ | ||
+ | </ | ||
+ | |||
+ | I.e. Output: | ||
+ | < | ||
+ | 012080 : Job times during startup < | ||
+ | 012080 : ================================================================ | ||
