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 (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

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

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

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().
And a few other things: UDP support is required (CONFIG_NET_UDP) and
signals must not be disabled (CONFIG_DISABLE_SIGNALS).
Given those prerequisites, the network monitor can be selected with these
additional settings.
System Type -> Kinetis Ethernet Configuration
CONFIG_ARCH_PHY_INTERRUPT=y : (auto-selected)
CONFIG_NETDEV_PHY_IOCTL=y : (auto-selected)
Application Configuration -> NSH Library -> Networking Configuration
CONFIG_NSH_NETINIT_THREAD : Enable the network initialization thread
CONFIG_NSH_NETINIT_MONITOR=y : Enable the network monitor
CONFIG_NSH_NETINIT_RETRYMSEC=2000 : Configure the network monitor as you like
CONFIG_NSH_NETINIT_SIGNO=18
LEDs
====
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
as follows:
SYMBOL Meaning LED1* LED2 LED3 LED4
------------------- ----------------------- ------- ------- ------- ------
LED_STARTED NuttX has been started OFF OFF OFF N/A
LED_HEAPALLOCATE Heap has been allocated OFF OFF OFF N/A
LED_IRQSENABLED Interrupts enabled OFF OFF OFF N/A
LED_STACKCREATED Idle stack created ON OFF OFF N/A
LED_INIRQ In an interrupt** N/C ON N/C N/A
LED_SIGNAL In a signal handler*** N/C N/C ON N/A
LED_ASSERTION An assertion failed ON ON ON N/A
LED_PANIC The system has crashed Blink N/C N/C N/A
LED_IDLE K64 is is sleep mode (Optional, not used)
* 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.
Development Environment
=======================
Either Linux or Cygwin on Windows can be used for the development environment.
The source has been built only using the GNU toolchain (see below). Other
toolchains will likely cause problems. Testing was performed using the Linux
environment.
GNU Toolchain Options
=====================
The NuttX make system has been modified to support the following different
toolchain options.
1. The CodeSourcery GNU toolchain,
2. The devkitARM GNU toolchain,
3. The NuttX buildroot Toolchain (see below).
All testing has been conducted using the CodeSourcery Windows toolchain. To
use the devkitARM or the NuttX GNU toolchain, you simply need to change the
the following configuration options to your .config (or defconfig) file:
CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery under Windows
CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYL=y : CodeSourcery under Linux
CONFIG_ARMV7M_TOOLCHAIN_IARL=y : IAR
CONFIG_ARMV7M_TOOLCHAIN_DEVKITARM=y : devkitARM under Windows
CONFIG_ARMV7M_TOOLCHAIN_BUILDROOT=y : NuttX buildroot under Linux or Cygwin
CONFIG_ARMV7M_TOOLCHAIN_GNU_EABIL=y : GCC (default)
If you are not using CONFIG_ARMV7M_TOOLCHAIN_BUILDROOT, then you may also have to modify
the PATH in the setenv.h file if your make cannot find the tools.
NOTE: the CodeSourcery (for Windows) and devkitARM toolchains are
Windows native toolchains. The CodeSourcey (for Linux) and NuttX buildroot
toolchains are Cygwin and/or Linux native toolchains. There are several limitations
to using a Windows based toolchain in a Cygwin environment. The three biggest are:
1. The Windows toolchain cannot follow Cygwin paths. Path conversions are
performed automatically in the Cygwin makefiles using the 'cygpath' utility
but you might easily find some new path problems. If so, check out 'cygpath -w'
2. Windows toolchains cannot follow Cygwin symbolic links. Many symbolic links
are used in Nuttx (e.g., include/arch). The make system works around these
problems for the Windows tools by copying directories instead of linking them.
But this can also cause some confusion for you: For example, you may edit
a file in a "linked" directory and find that your changes had no effect.
That is because you are building the copy of the file in the "fake" symbolic
directory. If you use a Windows toolchain, you should get in the habit of
making like this:
make clean_context all
An alias in your .bashrc file might make that less painful.
NOTE 1: The CodeSourcery toolchain (2009q1) does not work with default optimization
level of -Os (See Make.defs). It will work with -O0, -O1, or -O2, but not with
-Os.
NOTE 2: The devkitARM toolchain includes a version of MSYS make. Make sure that
the paths to Cygwin's /bin and /usr/bin directories appear BEFORE the devkitARM
path or will get the wrong version of make.
IDEs
====
NuttX is built using command-line make. It can be used with an IDE, but some
effort will be required to create the project.
Makefile Build
--------------
Under Eclipse, it is pretty easy to set up an "empty makefile project" and
simply use the NuttX makefile to build the system. That is almost for free
under Linux. Under Windows, you will need to set up the "Cygwin GCC" empty
makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
there is a lot of help on the internet).
Native Build
------------
Here are a few tips before you start that effort:
1) Select the toolchain that you will be using in your .config file
2) Start the NuttX build at least one time from the Cygwin command line
before trying to create your project. This is necessary to create
certain auto-generated files and directories that will be needed.
3) Set up include pathes: You will need include/, arch/arm/src/k40,
arch/arm/src/common, arch/arm/src/armv7-m, and sched/.
4) All assembly files need to have the definition option -D __ASSEMBLY__
on the command line.
Startup files will probably cause you some headaches. The NuttX startup file
is arch/arm/src/kinetis/k40_vectors.S.
NuttX EABI "buildroot" Toolchain
================================
A GNU GCC-based toolchain is assumed. The files */setenv.sh should
be modified to point to the correct path to the Cortex-M4 GCC toolchain (if
different from the default in your PATH variable).
If you have no Cortex-M4 toolchain, one can be downloaded from the NuttX
Bitbucket download site (https://bitbucket.org/nuttx/buildroot/downloads/).
This GNU toolchain builds and executes in the Linux or Cygwin environment.
NOTE: The NuttX toolchain may not include optimizations for Cortex-M4 (ARMv7E-M).
1. You must have already configured Nuttx in <some-dir>/nuttx.
cd tools
./configure.sh twr-k64f120m/<sub-dir>
2. Download the latest buildroot package into <some-dir>
3. unpack the buildroot tarball. The resulting directory may
have versioning information on it like buildroot-x.y.z. If so,
rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
4. cd <some-dir>/buildroot
5. cp configs/cortexm3-eabi-defconfig-4.6.3 .config
6. make oldconfig
7. make
8. Edit setenv.h, if necessary, so that the PATH variable includes
the path to the newly built binaries.
See the file configs/README.txt in the buildroot source tree. That has more
details PLUS some special instructions that you will need to follow if you are
building a Cortex-M4 toolchain for Cygwin under Windows.
NOTE: Unfortunately, the 4.6.3 EABI toolchain is not compatible with the
the NXFLAT tools. See the top-level TODO file (under "Binary loaders") for
more information about this problem. If you plan to use NXFLAT, please do not
use the GCC 4.6.3 EABI toochain; instead use the GCC 4.3.3 OABI toolchain.
See instructions below.
NuttX OABI "buildroot" Toolchain
================================
The older, OABI buildroot toolchain is also available. To use the OABI
toolchain:
1. When building the buildroot toolchain, either (1) modify the cortexm3-eabi-defconfig-4.6.3
configuration to use EABI (using 'make menuconfig'), or (2) use an exising OABI
configuration such as cortexm3-defconfig-4.3.3
2. Modify the Make.defs file to use the OABI conventions:
+CROSSDEV = arm-nuttx-elf-
+ARCHCPUFLAGS = -mtune=cortex-m3 -march=armv7-m -mfloat-abi=soft
+NXFLATLDFLAGS2 = $(NXFLATLDFLAGS1) -T$(TOPDIR)/binfmt/libnxflat/gnu-nxflat-gotoff.ld -no-check-sections
-CROSSDEV = arm-nuttx-eabi-
-ARCHCPUFLAGS = -mcpu=cortex-m3 -mthumb -mfloat-abi=soft
-NXFLATLDFLAGS2 = $(NXFLATLDFLAGS1) -T$(TOPDIR)/binfmt/libnxflat/gnu-nxflat-pcrel.ld -no-check-sections
NXFLAT Toolchain
================
If you are *not* using the NuttX buildroot toolchain and you want to use
the NXFLAT tools, then you will still have to build a portion of the buildroot
tools -- just the NXFLAT tools. The buildroot with the NXFLAT tools can
be downloaded from the NuttX Bitbucket download site
(https://bitbucket.org/nuttx/nuttx/downloads/).
This GNU toolchain builds and executes in the Linux or Cygwin environment.
1. You must have already configured Nuttx in <some-dir>/nuttx.
cd tools
./configure.sh lpcxpresso-lpc1768/<sub-dir>
2. Download the latest buildroot package into <some-dir>
3. unpack the buildroot tarball. The resulting directory may
have versioning information on it like buildroot-x.y.z. If so,
rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
4. cd <some-dir>/buildroot
5. cp configs/cortexm3-defconfig-nxflat .config
6. make oldconfig
7. make
8. Edit setenv.h, if necessary, so that the PATH variable includes
the path to the newly builtNXFLAT binaries.
TWR-K64F120M-specific Configuration Options

Configurations
==============
Each TWR-K64F120M configuration is maintained in a sub-directory and
can be selected as follow:
cd tools
./configure.sh twr-k64f120m/<subdir>
cd ..
. ./setenv.sh
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 initializeation 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.

* Name: board_app_initialize
*
* Description:
* Perform application specific initialization. This function is never
* called directly from application code, but only indirectly via the
* (non-standard) boardctl() interface using the command BOARDIOC_INIT.
*
* Input Parameters:
* arg - The boardctl() argument is passed to the board_app_initialize()
* implementation without modification. The argument has no
* meaning to NuttX; the meaning of the argument is a contract
* between the board-specific initalization logic and the the
* matching application logic. The value cold be such things as a
* mode enumeration value, a set of DIP switch switch settings, a
* pointer to configuration data read from a file or serial FLASH,
* or whatever you would like to do with it. Every implementation
* should accept zero/NULL as a default configuration.
*
* Returned Value:
* Zero (OK) is returned on success; a negated errno value is returned on
* any failure to indicate the nature of the failure.
