<div dir="ltr"><div>Hi,<br>
<br>
Does anyone could run short cycle(<<1ms) well using Igh EtherCAT master for linux-RT of Cyclone V (ARM CortexA9 925Mhz) ?<br>
<br>
I got the linux-socfpga.git for downloading Linux-3.10-ltsi-rt.<br>
I already put the EtherCAT module & application on the Linux-RT Helio board for Cyclone V.<br>
It could run well as communication cycle as 10 ms.<br>
<br>
And the Ethernet port will block when using 1ms transmit rate.<br>SKIPPED datagram always occur.<br>
It seems that the delay of ethernet transmit/receive function is too long.<br></div>
<br>
Has anyone already verify the situation or anyone could point out the delay issue?<div class=""><div id=":lc" class="" tabindex="0"><img class="" src="https://ssl.gstatic.com/ui/v1/icons/mail/images/cleardot.gif"><br></div><div id=":lc" class="" tabindex="0">Thanks a lot.<br><br></div><div id=":lc" class="" tabindex="0"> Brian <br></div></div></div>
