[etherlab-users] Failed to execute SDO download: Protocol not supported

I am currently using a Beckhoff EL2502 PWM output card with the Etherlab 1.5.2 master using the generic ethernet driver. On startup, I am trying to set a PDO assignment SDO register using ecrt_master_sdo_download() and am getting an error back “Failed to execute SDO download: Protocol not supported”.
I am not able to set a PDO assignment SDO registers using the ecrt_slave_config_sdoX() calls…which from my reading of other mailing list posts is only used for configuration registers.
In turn, I was able to use the Ethercat Etherlab tool and change the PDO mapping so I assumed it is available from the application interface since they use the same calls (ioctl interface)
Beckhoff changed the firmware on the card and I’m trying to reassign the PDO’s to the old mappings… this isn’t the first time I’ve run into this problem so I'm looking for a solution for all cards that would have this problem. Ideally, id like to do it through the application interface and avoid running a script on startup that uses the tool.
Has anyone has success with doing this type of transaction?
