i have custom board with DP83867 with RGMII Interface connected through EMAC of Shrac SC587 when i directly work on custom Board it completely works fine but when i connect multiple boards (i.e More than 3 Dp83867 custom boards) it is having issues....... any one of 3 having issue other two works fine but this is not same all the time...... for example if board 1 fails 1st time board 2 and board 3 works 2nd time if i test 2 will have issue but 1 and 3 works...... does switch is producing any delays??
switch used was D-LINK DGS-1008A 8 port
Note: according datasheet of Dp83867 all the applicable settings are made like straps according to Strap Configuration of datasheet, master slave configuration full duplex and auto negotiation
please suggest us if anything else need to be done still
