The TWR-K64F120M features two expansion card-edge connectors that interface
|
|
to the Primary and Secondary Elevator boards in a Tower system. 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 (set 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 set 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 set board

|
Using the network with NSH
|
|
--------------------------
|
|
|
|
So what can you do with this networking support? 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
|
|

|
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

You can also log into the NSH from the host PC like this:
|
|
|
|

|
|

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 addition 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.

The TWR-K64F120M board has four LEDs labeled D5, D6, D7, D9 on the board. Usage of
|
|
these LEDs is defined in include/board.h and src/up_leds.c. They are encoded
|

|
* If LED1, LED2, LED3 are statically on, then NuttX probably failed to boot
|
|
and these LEDs will give you some indication of where the failure was
|
|
** The normal state is LED1 ON and LED2 faintly glowing. This faint glow
|
|
is because of timer interrupts and signal that result in the LED being
|
|
illuminated on a small proportion of the time.
|
|
*** LED3 may even glow faintlier then LED2 while signals are processed.

Configurations
|
|
==============
|
|
|
|
Each TWR-K64F120M configuration is maintained in a sub-directory and
|
|
can be selected as follow:
|
|
|
|
tools/configure.sh twr-k64f120m:<subdir>
|
|
|
|
Where <subdir> is one of the following:
|
|
|
|
nsh:
|
|
---
|
|
Configures the NuttShell (nsh) located at apps/examples/nsh. The
|
|
Configuration enables only the serial interface.
|
|
The serial console is on OpenSDA serial bridge. For access,
|
|
use $ miniterm.py -f direct /dev/ttyACM0 115200 from Linux PC
|
|
Support for the board's SDHC MicroSD card is included.
|
|
|
|
NOTES:
|
|
|
|
1. The SDHC driver is under work and currently support IRQ mode (no DMA):
|
|
|
|
CONFIG_KINETIS_SDHC=y : Enable the SDHC driver
|
|
|
|
CONFIG_MMCSD=y : Enable MMC/SD support
|
|
CONFIG_MMCSD_SDIO=y : Use the SDIO-based MMC/SD driver
|
|
CONFIG_MMCSD_NSLOTS=1 : One MMC/SD slot
|
|
|
|
CONFIG_FAT=y : Eable FAT file system
|
|
CONFIG_FAT_LCNAMES=n : FAT lower case name support
|
|
CONFIG_FAT_LFN=y : FAT long file name support
|
|
CONFIG_FAT_MAXFNAME=32 : Maximum length of a long file name
|
|
|
|
CONFIG_KINETIS_GPIOIRQ=y : Enable GPIO interrupts
|
|
CONFIG_KINETIS_PORTEINTS=y : Enable PortE GPIO interrupts
|
|
|
|
CONFIG_SCHED_WORKQUEUE=y : Enable the NuttX workqueue
|
|
|
|
CONFIG_NSH_ARCHINIT=y : Provide NSH initialization logic
|
|
|
|
netnsh:
|
|
------
|
|
This is the same config then nsh, but it adds Ethernet support with the
|
|
TWR-SER card. It includes telnetd in order to access nsh from Ethernet.
|
|
IP address defaults to 192.168.0.233/24.
|
|
|
|
NOTES:
|
|
|
|
1. See networking support for application and especially for jumper setting.
|
|
In this config, this is TWR-SER that clocks the MCU.
|
|
|
|
2. The PHY link negotiation is done at boot time only. If no link is then
|
|
available, a fallback mode is used at 10Mbs/half-duplex. Please make sure
|
|
your ethernet cable and switches are on before booting.
