Hi,
We have followed the EtherCAT example and have successfully created and compiled the project "ethercat_slave_full".
We have created the image for the SD card. Now we run into an unhandled exception when we try to run the application. See the attached log below.
We have used following versions:
- Processor SDK Linux Version: 08.02.00.02
- Processor SDK RTOS Version: 06.03.00.106
- PRU ICSS EtherCAT Slave Version: 01.00.10.00

At this point it would be good if you can help us, as we are currently evaluating processors and would like to do some tests with EtherCAT.
