Hi ,
We are using ethercat appl from SDK 1.1.0.3 on ICE AM3359 and were trying to build a hardware setup to measure Ethercat I/O update times (With Frames)
Can any one let us know how can we implement these below test procedure on ICE Board.
1) Output update time to be measure for ICE-2 Board
Procedure :
1) ICE-1 Board , Firmware is written to Turn on a GPIO Pin when it receives a frame from master
2) ICE-2 Board is used to turn on a Digital Output Pin
3) Measure the time difference between GPIO High to Digital output update
Note: Both ICE-1 and ICE-2 received the frame at same time ( Negligible frame forward time)
/*****************************************************************************************************************/
2) Input update time to be measure for ICE-2 Board
Procedure :
1) ICE-2 Board fed with Digital Input
2) ICE-1 Board , Firmware is written to Turn on a GPIO Pin when it returns a frame to master
3) Measure the time difference between GPIO High to Digital Input update.
Note: Both ICE-1 and ICE-2 returns the frame at same time ( Negligible frame forward time)
