|
USB Host Configuration
|
|
^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
The Lincoln 60 board supports a USB host interface. The hidkbd
|
|
example can be used to test this interface.
|
|
|
|
The NuttShell (NSH) lincoln60 can also be modified in order to support USB
|
|
host operations. To make these modifications, do the following:
|
|
|
|
1. First configure to build the NSH configuration from the top-level
|
|
NuttX directory:
|
|
|
|
./configure lincoln60/nsh
|
|
|
|
2. Then edit the top-level .config file to enable USB host. Make the
|
|
following changes:
|
|
|
|
CONFIG_LPC17_40_USBHOST=y
|
|
CONFIG_USBHOST=y
|
|
CONFIG_SCHED_WORKQUEUE=y
|
|
|
|
When this change is made, NSH should be extended to support USB flash
|
|
devices. When a FLASH device is inserted, you should see a device
|
|
appear in the /dev (pseudo) directory. The device name should be
|
|
like /dev/sda, /dev/sdb, etc. The USB mass storage device, is present
|
|
it can be mounted from the NSH command line like:
|
|
|
|
ls /dev
|
|
mount -t vfat /dev/sda /mnt/flash
|
|
|
|
Files on the connect USB flash device should then be accessible under
|
|
the mountpoint /mnt/flash.
|
|
|
|
Configurations
|
|
^^^^^^^^^^^^^^
|
|
|
|
Each Lincoln 60 configuration is maintained in a sub-directory and can be selected
|
|
as follow:
|
|
|
|
tools/configure.sh lincoln60:<subdir>
|
|
|
|
Where <subdir> is one of the following:
|
|
|
|
netnsh:
|
|
Configures the NuttShell (nsh) located at apps/examples/nsh. This
|
|
configuration is similar to the nsh configuration except that network
|
|
upport is enabled.
|
|
|
|
NOTES:
|
|
|
|
1. This configuration uses the mconf-based configuration tool. To
|
|
change this configurations using that tool, you should:
|
|
|
|
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
|
see additional README.txt files in the NuttX tools repository.
|
|
|
|
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
|
reconfiguration process.
|
|
|
|
2. This configuration is setup to build under Windows with Cygwin using
|
|
the CodeSourcery toolchain. That is, however, easily reconfigured.
|
|
|
|
3. This configuration uses a serial console on UART0 at 115200 8N1.
|
|
This is the serial port at the connector labelled COM1 on the
|
|
Lincoln 60.
|
|
|
|
3. This example does initializes the network, then NSH sequentially. It
|
|
does not use the NSH network monitor thread. There are two
|
|
consequences to this: 1) There will be a delay booting to the NSH
|
|
prompt while the network is brought up. This delay will normally be
|
|
small but it the network cable is unconnected, it can be very long
|
|
(you may thing that the firmware is hung). and 2) if the network is
|
|
unplugged, then re-connected. The network will not automatically be
|
|
brought back up. But you should be able to do that manually with
|
|
the NSH ifup command.
|
|
|
|
If you want better, more responsive network management, look into
|
|
the NSH network monitor thread.
|
|
|
|
nsh:
|
|
Configures the NuttShell (nsh) located at apps/examples/nsh.
|
|
|
|
NOTES:
|
|
|
|
1. This configuration uses the mconf-based configuration tool. To
|
|

|

|
|
|
|
b. Execute 'make menuconfig' in nuttx/ in order to start the
|

reconfiguration process.
|
|
|
|
2. This configuration is setup to build under Linux with the Nutt
|
|
buildroot toolchain. That is, however, easily reconfigured.
|
|
|
|
3. This configuration uses a serial console on UART0 at 115200 8N1.
|
|
This is the serial port at the connector labelled COM1 on the
|
|
Lincoln 60.
|
|
|
|
3. This configuration enables only the serial NSH interface. See
|
|
notes above for enabling USB host support in this configuration.
|
|
|
|
thttpd-binfs:
|
|
This builds the THTTPD web server example using the THTTPD and
|
|
the apps/examples/thttpd application. This version uses the built-in
|
|
binary format with the BINFS file system and the Union File System.
|
|
|
|
NOTES:
|
|
|
|
1. Uses the CodeSourcery EABI toolchain under Windows. But that is
|
|
easily reconfigured:
|
|
|
|
CONFIG_HOST_WINDOWS=y : Windows
|
|
CONFIG_HOST_WINDOWS_CYGWIN=y : under Cygwin
|
|
CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery toolchain
|
|
|
|
STATUS:
|
|
2015-06-06: The BINFS CGI files are seems to be running, but the
|
|
output that they generate does not appear in the browser window.
|
|
I am suspecting that the redirected output is not working correctly
|
|
with the BINFS applications.
