Configurations
|

==============
|

|
|

|
Each EK-TM4C1294XL configuration is maintained in a
|
||||||
|
sub-directory and can be selected as follow:
|
||||||
|
|
||||||
|
cd tools
|
||||||
|
./configure.sh tm4c1294-launchpad/<subdir>
|
||||||
|
cd -

|
||||||

||||||
|
Where <subdir> is one of the following:
|
||||||
|
|
||||||
|
nsh:
|
||||||
|
---
|
||||||
|
Configures the NuttShell (nsh) located at apps/examples/nsh. The
|
||||||
|
configuration enables the serial ICDI vitual UART on UART0. Support for
|
||||||
|
builtin applications is enabled, but in the base configuration no
|
||||||
|
builtin applications are selected.
|
||||||
|
|
||||||
|
NOTES:
|
||||||
|
|
||||||
|
1. This configuration uses the mconf-based configuration tool. To
|
||||||
|
change this configuration using that tool, you should:
|
||||||
|
|
||||||
|
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
||||||
|
and misc/tools/
|
||||||
|
|
||||||
|
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
||||||
|
reconfiguration process.
|
||||||
|
|
||||||
|
2. By default, this configuration uses the CodeSourcery toolchain
|
||||||
|
for Windows and builds under Cygwin (or probably MSYS). That
|
||||||
|
can easily be reconfigured, of course.
|
||||||
|
|
||||||
|
CONFIG_HOST_LINUX=y : Linux (Cygwin under Windows okay too).
|
||||||
|
CONFIG_ARMV7M_TOOLCHAIN_BUILDROOT=y : Buildroot (arm-nuttx-elf-gcc)
|
||||||
|
CONFIG_RAW_BINARY=y : Output formats: ELF and raw binary
|
||||||
|
|
||||||
|
3. Default stack sizes are large and should really be tuned to reduce
|
||||||
|
the RAM footprint:
|
||||||
|
|
||||||
|
CONFIG_SCHED_HPWORKSTACKSIZE=2048
|
||||||
|
CONFIG_IDLETHREAD_STACKSIZE=1024
|
||||||
|
CONFIG_USERMAIN_STACKSIZE=2048
|
||||||
|
CONFIG_PTHREAD_STACK_DEFAULT=2048
|
||||||
|
CONFIG_POSIX_SPAWN_PROXY_STACKSIZE=1024
|
||||||
|
CONFIG_TASK_SPAWN_DEFAULT_STACKSIZE=2048
|
||||||
|
CONFIG_BUILTIN_PROXY_STACKSIZE=1024
|
||||||
|
CONFIG_NSH_TELNETD_DAEMONSTACKSIZE=2048
|
||||||
|
CONFIG_NSH_TELNETD_CLIENTSTACKSIZE=2048
|
||||||
|
|
||||||
|
4. This configuration has the network enabled by default. See the
|
||||||
|
paragraph "Using the network with NSH" in the DK-TM4C129X README).
|
||||||
|
|
||||||
|
Networking can easily be disabled or reconfigured (See see the
|
||||||
|
network related configuration settings in the section entitled
|
||||||
|
"Networking" in the DK-TM4C129X README).
|
||||||
|
|
||||||
|
By default, this configuration assumes a 10.0.0.xx network. It
|
||||||
|
uses a fixed IP address of 10.0.0.2 and assumes that the host is
|
||||||
|
at 10.0.0.1 and that the host provides the default router. The
|
||||||
|
network mask is 255.255.255.0. These address can be changed by
|
||||||
|
modifying the settings in the configuration. DHCPC can be enabled
|
||||||
|
be modifying this default configuration (See the "Networking"
|
||||||
|
section in the DK-TM4C129X README).
|
||||||
|
|
||||||
|
The network initialization thread is enabled in this example. NSH
|
||||||
|
will create a separate thread when it starts to initialize the
|
||||||
|
network. This eliminates start-up delays to bring the network. This
|
||||||
|
feature may be disabled by reverting the configuration as described
|
||||||
|
under "Network Initialization Thread" in the DK-TM4C129X README.
|
||||||
|
|
||||||
|
The persistent network monitor thread is also available in this
|
||||||
|
configuration. The network monitor will monitor changes in the
|
||||||
|
link status and gracefully take the network down when the link is
|
||||||
|
lost (for example, if the cable is disconnected) and bring the
|
||||||
|
network back up when the link becomes available again (for example,
|
||||||
|
if the cable is reconnected). See the paragraph "Network Monitor"
|
||||||
|
in the DK-TM4C129X README for additional information.
|
||||||
|
|
||||||
|
ipv6:
|
||||||
|
----
|
||||||
|
This is another version of the NuttShell configuration. It is very
|
||||||
|
similar to the nsh configuration except that it has IPv6 enabled and
|
||||||
|
IPv4 disabled. Several network utilities that are not yet available
|
||||||
|
under IPv6 are disabled.
|
||||||
|
|
||||||
|
NOTES:
|
||||||
|
|
||||||
|
1. As of 2015-02-12, this configuration was identical to the nsh
|
||||||
|
configuration other than using IPv6. So all of the notes above
|
||||||
|
regarding the nsh configuration apply.
|
||||||
|
|
||||||
|
Telnet does not work with IPv6.
|
||||||
|
|
||||||
|
2. This configuration can be modified to that both IPv4 and IPv6
|
||||||
|
are support. Here is a summary of the additional configuration
|
||||||
|
settings requird to support both IPv4 and IPv6:
|
||||||
|
|
||||||
|
CONFIG_NET_IPv4=y
|
||||||
|
CONFIG_NET_ARP=y
|
||||||
|
CONFIG_NET_ARP_SEND=y (optional)
|
||||||
|
CONFIG_NET_ICMP=y
|
||||||
|
CONFIG_NET_ICMP_PING=y
|
||||||
|
|
||||||
|
CONFIG_NETUTILS_DNSCLIENT=y
|
||||||
|
CONFIG_NETUTILS_DNSCLIENT_IPv4=y
|
||||||
|
CONFIG_NETUTILS_TELNETD=y
|
||||||
|
|
||||||
|
CONFIG_NSH_IPADDR=0x0a000002
|
||||||
|
CONFIG_NSH_DRIPADDR=0x0a000001
|
||||||
|
CONFIG_NSH_NETMASK=0xffffff00
|
||||||
|
CONFIG_NSH_TELNET=y
|
||||||
|
|
||||||
|
Then from NSH, you have both ping and ping6 commands:
|
||||||
|
|
||||||
|
nsh> ping 10.0.0.1
|
||||||
|
nsh> ping6 fc00::1
|
||||||
|
|
||||||
|
And from the host you can do similar:
|
||||||
|
|
||||||
|
ping 10.0.0.2
|
||||||
|
ping6 fc00::2 (Linux)
|
||||||
|
ping -6 fc00::2 (Windows cmd)
|
||||||
|
|
||||||
|
and Telnet again works from the host:
|
||||||
|
|
||||||
|
telnet 10.0.0.2
|
||||||
|
|
||||||
|
3. You can enable IPv6 autonomous address configuration with the
|
||||||
|
following changes to the configuration:
|
||||||
|
|
||||||
|
+ CONFIG_NET_ICMPv6_AUTOCONF=y
|
||||||
|
+ CONFIG_ICMPv6_AUTOCONF_DELAYMSEC=100
|
||||||
|
+ CONFIG_ICMPv6_AUTOCONF_MAXTRIES=5
|
||||||
|
|
||||||
|

|
||||||
|
- CONFIG_NSH_DRIPv6ADDR_2=0x0000
|
||||||
|

|

|
||||||
|

|
||||||
|
|
||||||
|
- CONFIG_NSH_IPv6ADDR_1=0xfc00
|
