[etherlab-dev] Failed to register PDO entry: No such file or directory -- PDO entry 0x7030:01 is not mapped

[Matthys Schnetler]

Hi Florian,

Thank you for the speedy response.

Yes I do use ecrt_slave_config_pdos() with the correct arguments, I know this because I have placed a few debug messages and it executes without returning any errors.

>Returning nothing means that no configuration was applied. Is your

My application starts up yes but the moment that error pops the master is released by Ethercat itself as can be seen below from dmesg:

[12589.250526] EtherCAT ERROR 0 28672:257: PDO entry 0x7030:01 is not mapped.
[12592.174416] EtherCAT 0: Releasing master...
[12592.174465] EtherCAT 0: Released.

I can work in the application without problems but I disable my txandrx to ethercat because I get segmentation faults if I read or write to it in this condition.

Regards

Matthys

Did you supply the data structures to the master using
ecrt_slave_config_pdos()?

Returning nothing means that no configuration was applied. Is your
application running?
