The Primary Connector (comprised of sides A and B) is identified by a white strip. The Secondary Connector is comprised of sides C and D. TWR-SER Serial Board Connection =============================== The serial board connects into the tower and then maps to the tower pins to yet other functions (see TWR-SER-SCH.pdf). In particular it features an Ethernet port. Networking Support ================== U2 is a 25 MHz oscillator (which may be disabled by setting J4), which clock is sent to U1. U1 has two clock output banks: 25MHz (CLKBx) and 50MHz (CLKAx). J2 (ser board) is used to select the PHY clock source: 50MHz, 25MHz or CLCKOUT0 from K64. Set it to 25MHz. In order to keep synchornized the PHY clock with the K64 clock, one can set J3 (default is open) to route CLOCKIN0 either from 25MHz or 50Mhz lines. In that case, J33 (main board) will have to be removed and J32 (main board set) set to disable its 50MHz_OSC and use CLKIN0 provided by ser board. J12 is by default set to RMII mode. In this case J2 should be placed to 50MHz clock Note that in MII mode, MII0_TXER is required by kinetis driver, but not connected on ser board Ethernet MAC/KSZ8041NL PHY -------------------------- ------------ ---------------------------------------------------------- ------------------------------ ------------------------------- KSZ8041 TWR Board Signal(s) K64F Pin Pin name Pin Signal Function MII RMII --- -------- ---------------------------------------------------------- ------------------------------ ------------------------------- 9 REFCLK CLK_SEL J2: CLOCKOUT0/25MHz/50MHz, PHY clock input PTC3/CLKOUT --- direct to PHY 11 MDIO FEC_MDIO PTB0/RMII0_MDIO/MII0_MDIO PIN_MII0_MDIO PIN_RMII0_MDIO 12 MDC FEC_MDC PTB1/RMII0_MDC/MII0_MDC PIN_MII0_MDC PIN_RMII0_MDC 13 PHYAD0 FEC_RXD3 J12: PHY Adress select (pull-down if set) PTA9/MII0_RXD3 PIN_RMII0_RXD3 --- 14 PHYAD1 FEC_RXD2 J12: PHY Adress select (pull-up if set) PTA10/MII0_RXD2 PIN_RMII0_RXD2 --- 15 PHYAD2 FEC_RXD1 J12: PHY Adress select (pull-up if set) PTA12/RMII0_RXD1/MII0_RXD1 PIN_MII0_RXD1 PIN_RMII0_RXD1 16 DUPLEX FEC_RXD0 J12: Half-duplex (pull-down if set) PTA13/RMII0_RXD0/MII0_RXD0 PIN_MII0_RXD0 PIN_RMII0_RXD0 18 CONFIG2 FEC_RXDV J12: Loopback select (pull-up if set) PTA14/RMII0_CRS_DV/MII0_RXDV PIN_MII0_RXDV PIN_RMII0_CRS_DV 19 RXC FEC_RXCLK PTA11/MII0_RXCLK PIN_MII0_RXCLK --- 20 ISO FEC_RXER J12: Isolation mode select (pull-up if set) PTA5/RMII0_RXER/MII0_RXER PIN_MII_RXER PIN_RMII_RXER 22 TXC FEC_TXCLK PTA25/MII0_TXCLK PIN_MII0_TXCLK --- 23 TXEN FEC_TXEN PTA15/RMII0_TXEN/MII0_TXEN PIN_MII0_TXEN PIN_RMII0_TXEN 24 TXD0 FEC_TXD0 PTA16/RMII0_TXD0/MII0_TXD0 PIN_MII0_TXD0 PIN_RMII0_TXD0 25 TXD1 FEC_TXD1 PTA17/RMII0_TXD1/MII0_TXD1 PIN_MII0_TXD1 PIN_RMII0_TXD1 26 TXD2 FEC_TXD2 PTA24/MII0_TXD2 PIN_MII0_TXD2 --- 27 TXD3 FEC_TXD3 PTA26/MII0_TXD3 PIN_MII0_TXD3 --- 28 CONFIG0 FEC_COL J12: RMII select (pull-up if set) PTA29/MII0_COL PIN_MII0_COL --- 29 CONFIG1 FEC_CRS PTA27/MII0_CRS PIN_MII0_CRS --- 30 LED0 LED0/NWAYEN J12: Disable auto_negotiation (pull-down if s --- --- 31 LED1 LED1/SPEED J12: 10Mbps select (pull-down if set) --- --- --- -------- ----------------- ---------------------------------------- ------------------------------ ------------------------------- Networking support can be added to NSH by selecting the following configuration options.

First you see that NSH has several new network related commands: ifconfig, ifdown, ifup: Commands to help manage your network get and put: TFTP file transfers wget: HTML file transfers ping: Check for access to peers on the network Telnet console: You can access the NSH remotely via telnet. You can also enable other add on features like full FTP or a Web Server or XML RPC and others. There are also other features that you can enable like DHCP client (or server) or network name resolution. By default, the IP address of the DK-TM4C129X will be 192.168.0.233 and it will assume that your host is the gateway and has the IP address 192.168.0.254. nsh> ifconfig eth0 Link encap:Ethernet HWaddr 16:03:60:0f:00:33 at UP inet addr:192.168.0.233 DRaddr:192.168.0.254 Mask:255.255.255. You can use ping to test for connectivity to the host (Careful, Window firewalls usually block ping-related ICMP traffic). On the host PC side, you may be able to ping the TWR-K64F120M: $ ping 192.168.0.233 PING 192.168.0.233 (192.168.0.233) 56(84) bytes of data. 64 bytes from 192.168.0.233: icmp_seq=1 ttl=64 time=7.82 ms 64 bytes from 192.168.0.233: icmp_seq=2 ttl=64 time=4.50 ms 64 bytes from 192.168.0.233: icmp_seq=3 ttl=64 time=2.04 ms ^C --- 192.168.0.233 ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2003ms rtt min/avg/max/mdev = 2.040/4.789/7.822/2.369 ms From the target side, you may should also be able to ping the host (assuming it's IP is 192.168.0.1): nsh> ping 192.168.0.1 PING 192.168.0.1 56 bytes of data 56 bytes from 192.168.0.1: icmp_seq=1 time=0 ms 56 bytes from 192.168.0.1: icmp_seq=2 time=0 ms 56 bytes from 192.168.0.1: icmp_seq=3 time=0 ms 56 bytes from 192.168.0.1: icmp_seq=4 time=0 ms 56 bytes from 192.168.0.1: icmp_seq=5 time=0 ms 56 bytes from 192.168.0.1: icmp_seq=6 time=0 ms 56 bytes from 192.168.0.1: icmp_seq=7 time=0 ms 56 bytes from 192.168.0.1: icmp_seq=8 time=0 ms 56 bytes from 192.168.0.1: icmp_seq=9 time=0 ms 56 bytes from 192.168.0.1: icmp_seq=10 time=0 ms 10 packets transmitted, 10 received, 0% packet loss, time 10100 ms nsh> You can also log into the NSH from the host PC like this: $ telnet 192.168.0.233 Trying 192.168.0.233... Connected to 192.168.0.233. Escape character is '^]'. NuttShell (NSH) nsh> NOTE: If you enable this networking as described above, you will experience a delay on booting NSH. That is because the start-up logic waits for the network connection to be established before starting NuttX. In a real application, you would probably want to do the network bringup on a separate thread so that access to the NSH prompt is not delayed. The kinetis_enet.c driver, does not wait too long for PHY to negotiate the link speed. In this case it folds back to 10Mbs half-duplex mode. This behaviour should be improved in order to cope with the plug and play nature of this port. Reconfiguring after the network becomes available requires the network monitor feature, also discussed below. Network Initialization Thread ----------------------------- [not tested on K64F120M] There is a configuration option enabled by CONFIG_NSH_NETINIT_THREAD that will do the NSH network bring-up asynchronously in parallel on a separate thread. This eliminates the (visible) networking delay altogether. This current implementation, however, has some limitations: - If no network is connected, the network bring-up will fail and the network initialization thread will simply exit. There are no retries and no mechanism to know if the network initialization was successful (it could perform a network Ioctl to see if the link is up and it now, keep trying, but it does not do that now). - Furthermore, there is currently no support for detecting loss of network connection and recovery of the connection (similarly, this thread could poll periodically for network status, but does not). Both of these shortcomings could be eliminated by enabling the network monitor: Network Monitor --------------- By default the network initialization thread will bring-up the network then exit, freeing all of the resources that it required. This is a good behavior for systems with limited memory. If the CONFIG_NSH_NETINIT_MONITOR option is selected, however, then the network initialization thread will persist forever; it will monitor the network status. In the event that the network goes down (for example, if a cable is removed), then the thread will monitor the link status and attempt to bring the network back up. In this case the resources required for network initialization are never released. Pre-requisites: - CONFIG_NSH_NETINIT_THREAD as described above. - The K64F EMAC block does not support PHY interrupts. The KSZ8081 PHY interrupt line is brought to a jumper block and it should be possible to connect that some some interrupt port pin. You would need to provide some custom logic in the Freedcom K64F configuration to set up that PHY interrupt. - In addtion to the PHY interrupt, the Network Monitor also requires the following setting: CONFIG_NETDEV_PHY_IOCTL. Enable PHY IOCTL commands in the Ethernet device driver. Special IOCTL commands must be provided by the Ethernet driver to support certain PHY operations that will be needed for link management. There operations are not complex and are implemented for the Atmel SAMA5 family. CONFIG_ARCH_PHY_INTERRUPT. This is not a user selectable option. Rather, it is set when you select a board that supports PHY interrupts. For the K64F, like most other architectures, the PHY interrupt must be provided via some board-specific GPIO. In any event, the board-specific logic must provide support for the PHY interrupt. To do this, the board logic must do two things: (1) It must provide the function arch_phy_irq() as described and prototyped in the nuttx/include/nuttx/arch.h, and (2) it must select CONFIG_ARCH_PHY_INTERRUPT in the board configuration file to advertise that it supports arch_phy_irq(). One other thing: UDP support is required (CONFIG_NET_UDP). Given those prerequisites, the network monitor can be selected with these additional settings.
