Are you running 2.7.0? Jeff Epler fixed some random startup issues with hm2_eth fairly recently these are fixed in the released version 2.7.0 Also if this is with your remote hardware (not Mesa FPGA hardware), there may be possible data loss with all the write only initialization data sent at startup with no checking for possible buffer overflows. This is pretty well masked with our hardware since its pretty fast and has a 12K byte receive packet buffer in the Ethernet chip. > > ------------------------------------------------------------------------------ > _______________________________________________ > Emc-users mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/emc-users > Peter Wallace Mesa Electronics (\__/) (='.'=) This is Bunny.
