Dear All, We have worked with bring-up the BSP for Altera Cyclone V processor.Now we were working with kitl through ethernet and We got some kitl debug print.After some time "System gone to Hang".I have given Platform builder Debug prints as well as what're the prints we got in UART. ******************* UART Prints ********************** DHCP Renew successful, IP = 192.168.2.11, Lease time = 300 seconds -KitlEthDecode(pData = 0x0, length = 369) KITL: DHCP get device IP: 192.168.2.11 VBridge:: built on [Aug 22 2013] time [16:09:12] VBridgeInit()...TX = [16384] bytes -- Rx = [16384] bytes Tx buffer [0x860E1D80] to [0x860E5D80].
