Hello all,
I am trying to run the app_demo_slave_ethercat_motorcontrol with app_demo_master_cyclic_position. When I compile the slave side, I get the following error:
Constraint check for “tile[3]” (node “3”, tile 0):
Cores available: 8, used: 7 . OKAY
Timers available: 10, used: 8 . OKAY
Chanends available: 32, used: 34 . FAILED
I am using QEI_SENSOR (If I use BISS_SENSOR, the code compiles).
So I commented out the gpio_service and the code compiles now. But the problem is when I run the master side, the output shows till only ‘Activating Master and Started’. I did a backtrace and found the code goes into init_nodes()->write_sdo() and then its stops.
I also tried the same with watchdog_service commented out but the same thing happened.
Can somebody tell me what is happening? How do I get the ethercat example to work? Am I doing something wrong?
I edited the motor parameters in bldc_motor_config_1.h. I am using a single motor. Should I have changed the parameters somewhere else as well?
Just bumping this up.
Could someone please help?
Did you had a solution to this problem ? Changing the code in the slave allowed me to compile, but I still have the problem when starting the master cyclic application with the encoder selected as output. It hangs after updating the motor/control configuration.
Please look at this thread. Let me know if the suggestions there were helpful or you still have a problem.
I checked out the develop branch and did ethercat sii_write -p 0 Somanet_ECAT-v3r0.sii. But I am getting the following error:
Failed to write SII: Input/output error
When I do dmesg, I can see the following errors:
EtherCAT ERROR 0-0: SII: Error on last SII command!
EtherCAT ERROR 0-0: Failed to write SII data.
Am I doing something wrong?
Thanks!
Hi,
please make sure that the downloaded sii file is not corrupted.
Is the node you are updating has a zero position in your EtherCAT topology?
Unless there is a hardware or contact issue, flashing the sii file should go smoothly. Please also check without the debug adapter between the core module and the EtherCAT board.
Regards
It worked when I did –position.
But the example code is still not working. When running the example:
When I check dmesg, I can see ‘EtherCAT ERROR 0-0: Timeout after 1001 ms while waiting for SDO 0x2410:3 upload response.’
Also another error: ‘Ethercat ERROR 0-0: Reception of CoE upload request for SDO 0x6091:0 failed with timeout after 1001 ms: No response.’
And when the master prints ‘updating motor parameters for all connected nodes’, the slave receives ET_ECALL, Application exception and exits the code.
