mounting would be harmful.
USB Device Controller Support
==============================
USB Device Controller Support
-----------------------------
The USBHS device controller driver is enabled with he following
configurationsettings:
Device Drivers -> USB Device Driver Support
CONFIG_USBDEV=y : Enable USB device support
For full-speed/low-power mode:
CONFIG_USBDEV_DUALSPEED=n : Disable High speed support
For high-speed/normal mode:
CONFIG_USBDEV_DUALSPEED=y : Enable High speed support
CONFIG_USBDEV_DMA=y : Enable DMA methods
CONFIG_USBDEV_MAXPOWER=100 : Maximum power consumption
CONFIG_USBDEV_SELFPOWERED=y : Self-powered device
System Type -> Kinetis Peripheral Selection
CONFIG_KINETIS_USBOTG=y
CDC/ACM Device Class
--------------------
In order to be usable, you must all enabled some class driver(s) for the
USBHS device controller. Here, for example, is how to configure the CDC/ACM
serial device class:
Device Drivers -> USB Device Driver Support
CONFIG_CDCACM=y : USB Modem (CDC ACM) support
CONFIG_CDCACM_EP0MAXPACKET=64 : Enpoint 0 packet size
CONFIG_CDCACM_EPINTIN=1 : Interrupt IN endpoint number
CONFIG_CDCACM_EPINTIN_FSSIZE=64 : Full speed packet size
CONFIG_CDCACM_EPINTIN_HSSIZE=64 : High speed packet size
CONFIG_CDCACM_EPBULKOUT=3 : Bulk OUT endpoint number
CONFIG_CDCACM_EPBULKOUT_FSSIZE=64 : Full speed packet size
CONFIG_CDCACM_EPBULKOUT_HSSIZE=512 : High speed packet size
CONFIG_CDCACM_EPBULKIN=2 : Bulk IN endpoint number
CONFIG_CDCACM_EPBULKIN_FSSIZE=64 : Full speed packet size
CONFIG_CDCACM_EPBULKIN_HSSIZE=512 : High speed packet size
CONFIG_CDCACM_NWRREQS=4 : Number of write requests
CONFIG_CDCACM_NRDREQS=8 : Number of read requests
CONFIG_CDCACM_BULKIN_REQLEN=96 : Size of write request buffer (for full speed)
CONFIG_CDCACM_BULKIN_REQLEN=768 : Size of write request buffer (for high speed)
CONFIG_CDCACM_RXBUFSIZE=257 : Serial read buffer size
CONFIG_CDCACM_TXBUFSIZE=193 : Serial transmit buffer size (for full speed)
CONFIG_CDCACM_TXBUFSIZE=769 : Serial transmit buffer size (for high speed)
CONFIG_CDCACM_VENDORID=0x0525 : Vendor ID
CONFIG_CDCACM_PRODUCTID=0xa4a7 : Product ID
CONFIG_CDCACM_VENDORSTR="NuttX" : Vendor string
CONFIG_CDCACM_PRODUCTSTR="CDC/ACM Serial" : Product string
Device Drivers -> Serial Driver Support
CONFIG_SERIAL_REMOVABLE=y : Support for removable serial device
The CDC/ACM application provides commands to connect and disconnect the
CDC/ACM serial device:
CONFIG_SYSTEM_CDCACM=y : Enable connect/disconnect support
CONFIG_SYSTEM_CDCACM_DEVMINOR=0 : Use device /dev/ttyACM0
CONFIG_CDCACM_RXBUFSIZE=??? : A large RX may be needed
If you include this CDC/ACM application, then you can connect the CDC/ACM
serial device to the host by entering the command 'sercon' and you detach
the serial device with the command 'serdis'. If you do no use this
application, they you will have to write logic in your board initialization
code to initialize and attach the USB device.

NOTES:
1. Most of the notes associated with the nsh configuration apply here
as well (see below).
1. This configuration uses the mconf-based configuration tool. To
change this configuration using that tool, you should:
3. No external pullup is available on MDIO signal when MK64FN1M0VLL12 MCU
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. Default platform/toolchain:
CONFIG_HOST_WINDOWS=y : Cygwin under Windows
CONFIG_WINDOWS_CYGWIN=y
CONFIG_ARMV7M_TOOLCHAIN_GNU_EABIW=y : ARM/mbed toolcahin (arm-none-elf-gcc)
CONFIG_INTELHEX_BINARY=y : Output formats: Intel hex binary
3. The Serial Console is provided on UART3 with the correct pin
configuration for use with an Arduino Serial Shield.
4. SDHC support is not enabled in this configuration. Refer to the
configuration settings listed above under "SD Card Support".
5. No external pullup is available on MDIO signal when MK64FN1M0VLL12 MCU
is requests status of the Ethernet link connection. Internal pullup is
required when port configuration for MDIO signal is enabled:
CONFIG_KINETIS_ENET_MDIOPULLUP=y

4. An SDHC driver is has not yet been tested but can be enabled in the NSH
configuration by setting the following configuration values as follows:
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_LFN=y : FAT long file name support
CONFIG_FAT_MAXFNAME=32 : Maximum lenght of a long file name
CONFIG_GPIO_IRQ=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
4. An SDHC driver is enabled in this configuration but does not yet work.
The basic problem seems to be that it does not sense the presence of
the SD card on PTE6. No interrupts are generated when the SD card is
inserted or removed. You might want to disable SDHC and MMC/SD if
you are using this configuration. Refer to the configuration
settings listed above under "SD Card Support".
