CONFIG_NSH_NETINIT_SIGNO=18
USBHS Device Controller Driver
==============================
The USBHS device controller driver is enabled with he following configuration
settings:
Device Drivers -> USB Device Driver Support
CONFIG_USBDEV=y : Enable USB device support
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 -> SAMV7 Peripheral Selection
CONFIG_SAMV7_USBDEVHS=y
System Type -> SAMV7 USB High Sppeed Device Controller (DCD options
CONFIG_SAMV7_USBHS_NDTDS=8 : Number of DMA transfer descriptors
CONFIG_SAMV7_USBHS_PREALLOCATE=y : Pre-allocate descriptors
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_NRDREQS=4 : Number of read requests
CONFIG_CDCACM_NWRREQS=4 : Number of write requests
CONFIG_CDCACM_BULKIN_REQLEN=768 : Size of write request buffer
CONFIG_CDCACM_RXBUFSIZE=256 : Serial read buffer size
CONFIG_CDCACM_TXBUFSIZE=256 : Serial transmit buffer size
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
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.

This port uses a primitive, emulated Z80 and the SDCC toolchain.
This port uses an instructino set simulator called z80sim.
This port uses an instruction set simulator called z80sim.
The SDCC toolchain is available from http://sdcc.sourceforge.net/. All
testing has been performed using version 2.6.0 of the SDCC toolchain.
