USB Host Configuration
Configurations
mcb1700 Configuration Options
^^^^^^^^^^^^^^^^^^^^^^^^^^
CONFIG_ARCH - Identifies the arch/ subdirectory. This should
be set to:
CONFIG_ARCH=arm
CONFIG_ARCH_family - For use in C code:
CONFIG_ARCH_ARM=y
CONFIG_ARCH_architecture - For use in C code:
CONFIG_ARCH_CORTEXM3=y
CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
CONFIG_ARCH_CHIP=lpc17xx
CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
chip:
CONFIG_ARCH_CHIP_LPC1768=y
CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
hence, the board that supports the particular chip or SoC.
CONFIG_ARCH_BOARD=mcb1700 (for the mcb1700.org board)
CONFIG_ARCH_BOARD_name - For use in C code
CONFIG_ARCH_BOARD_MCB1700=y
CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
of delay loops
CONFIG_ENDIAN_BIG - define if big endian (default is little
endian)
CONFIG_RAM_SIZE - Describes the installed DRAM (CPU SRAM in this case):
CONFIG_RAM_SIZE=(32*1024) (32Kb)
There is an additional 32Kb of SRAM in AHB SRAM banks 0 and 1.
CONFIG_RAM_START - The start address of installed DRAM
CONFIG_RAM_START=0x10000000
CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
have LEDs
CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
stack. If defined, this symbol is the size of the interrupt
stack in bytes. If not defined, the user task stacks will be
used during interrupt handling.
CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to board architecture.
CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
cause a 100 second delay during boot-up. This 100 second delay
serves no purpose other than it allows you to calibratre
CONFIG_ARCH_LOOPSPERMSEC. You simply use a stop watch to measure
the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
the delay actually is 100 seconds.
Individual subsystems can be enabled:
CONFIG_LPC17_MAINOSC=y
CONFIG_LPC17_PLL0=y

(the CCLK frequency is divided by this number to get the CAN clock).
Options = {1,2,4,6}. Default: 4.
CONFIG_CAN2_DIVISOR - CAN2 is clocked at CCLK divided by this number.
(the CCLK frequency is divided by this number to get the CAN clock).
Options = {1,2,4,6}. Default: 4.
CONFIG_CAN_TSEG1 - The number of CAN time quanta in segment 1. Default: 6
CONFIG_CAN_TSEG2 = the number of CAN time quanta in segment 2. Default: 7
LPC17xx specific PHY/Ethernet device driver settings. These setting
also require CONFIG_NET and CONFIG_LPC17_ETHERNET.
CONFIG_ETH0_PHY_KS8721 - Selects Micrel KS8721 PHY

Enable reading SOF from interrupt handler vs. simply reading on demand.
Probably a bad idea... Unless there is some issue with sampling the SOF
from hardware asynchronously.
CONFIG_LPC17_USBDEV_EPFAST_INTERRUPT
Enable high priority interrupts. I have no idea why you might want to
do that
CONFIG_LPC17_USBDEV_NDMADESCRIPTORS

CONFIG_USBHOST_TDBUFFERS
Number of transfer descriptor buffers
CONFIG_USBHOST_TDBUFSIZE
Size of one transfer descriptor buffer
CONFIG_USBHOST_IOBUFSIZE
Size of one end-user I/O buffer. This can be zero if the
application can guarantee that all end-user I/O buffers
reside in AHB SRAM.
USB Host Configuration
^^^^^^^^^^^^^^^^^^^^^^
The mcb1700 board can be easily modified to support a USB host interface
(Remember to add 2 resistors of 15K to D+ and D- pins).
The NuttShell (NSH) mcb1700 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:
cd tools
./configure mcb1700/nsh
cd ..
2. Then edit the top-level .config file to enable USB host. Make the
following changes using 'make menuconfig':
System Type -> LPC17xx Peripheral Support
CONFIG_LPC17_USBHOST=y : USB host controller driver support
Device Drivers -> USB Host Driver Support
CONFIG_USBHOST=y : USB host support
CONFIG_USBHOST_ISOC_DISABLE=y : Not needed
CONFIG_USBHOST_MSC=y : Mass storage class support
Library Routines
CONFIG_SCHED_WORKQUEUE=y : Enable worker thread
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
^^^^^^^^^^^^^^
General
-------
Each mcb1700 configuration is maintained in a sub-directory and can be selected
as follow:
cd tools
./configure.sh mcb1700/<subdir>
cd -
Where <subdir> is one of the mcb1700 subdirectories described in the
following paragraph.
NOTES:
1. These configurations use the mconf-based configuration tool. To
change any of these 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.
Configuration Sub-directories
-----------------------------
nsh:
Configures the NuttShell (nsh) located at examples/nsh. The
Configuration enables only the serial NSH interfaces. See notes
above for enabling USB host support in this configuration.

*
* 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
* 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.
