-CAN Usage
-=========
-  I planned to verify CAN using the IXXAT USB-to-CAN Compact.  This section
-  provides miscellaneous CAN-related notes, mostly to myself but perhaps of
-  interest to others.
-
-  [Unfortunately, as of this writing, I still do not have a proper CAN test
-   bed to verify the CAN driver.]
-
-  CAN Configuration
-  -----------------
-
-  The following steps illustrate how to enable CAN0 and/or CAN1 in the NuttX
-  configuration:
-
-    System Type -> SAMA5 Peripheral Support
-       CONFIG_SAMA5_CAN0=y            : Select CAN0 and/or CAN1
-       CONFIG_SAMA5_CAN1=y
-
-    Device Drivers -> CAN Driver Support
-       CONFIG_CAN=y                   : (Automatically selected)
-       CONFIG_CAN_EXTID=y             : For extended, 29-bit CAN IDs
-
-    System Type -> CAN Drive Support
-       CONFIG_SAMA5_CAN0_BAUD=250000  : Select some BAUD for CAN0 (if enabled)
-       CONFIG_SAMA5_CAN0_NRECVMB=1    : Select number of receive mailboxes (see below)
-       CONFIG_SAMA5_CAN1_BAUD=250000  : Select some BAUD for CAN1 (if enabled)
-       CONFIG_SAMA5_CAN1_NRECVMB=1    : Select number of receive mailboxes (see below)
-
-  Receive Mailboxes and Address Filtering
-  ---------------------------------------
-
-  The SAMA5 CAN0 peripheral supports 8 mailboxes that can be used for sending
-  and receiving messages.  Note that the number of dedicated receive mailboxes
-  (CONFIG_SAMA5_CANn_NRECVMB) was set to one in the above configuration.  This
-  could be set to any value from 1 to 3 (the upper limit of 3 is purely
-  arbrary and can be increased with some minor code enhancement).  The
-  remainder can be configured dynamically to send CAN messages.
-
-  Why would you want to use more than one receive mailbox?  There are two
-  reasons. Multiple receive mailboxes might needed to either (1) receive
-  bursts of messages, or (2) to support multiple groups of messages filtered
-  on message ID.
-
-  You must also specify the address filtering for each dedicated receive mailbox:
-
-    System Type -> CAN Drive Support
-       CONFIG_SAMA5_CAN0_ADDR0 and CONFIG_SAMA5_CAN0_MASK0 : If CONFIG_SAMA5_CAN0_NRECVMB >= 1
-       CONFIG_SAMA5_CAN0_ADDR1 and CONFIG_SAMA5_CAN0_MASK1 : If CONFIG_SAMA5_CAN0_NRECVMB >= 2
-       CONFIG_SAMA5_CAN0_ADDR2 and CONFIG_SAMA5_CAN0_MASK2 : If CONFIG_SAMA5_CAN0_NRECVMB >= 3
-       CONFIG_SAMA5_CAN1_ADDR0 and CONFIG_SAMA5_CAN1_MASK0 : If CONFIG_SAMA5_CAN1_NRECVMB >= 1
-       CONFIG_SAMA5_CAN1_ADDR1 and CONFIG_SAMA5_CAN1_MASK1 : If CONFIG_SAMA5_CAN1_NRECVMB >= 2
-       CONFIG_SAMA5_CAN1_ADDR2 and CONFIG_SAMA5_CAN1_MASK2 : If CONFIG_SAMA5_CAN1_NRECVMB >= 3
-
-  Only messages that have IDs that match the CONFIG_SAMA5_CANn_ADDRn when both
-  the received and the configured address are masked by CONFIG_SAMA5_CANn_MASKn
-  will be accepted.  For example, if the mask is all ones, then only messasges
-  with exact address matches will be accepted; if the mask is all zeroes than
-  any address will be accepted.
-
-  CAN connectors
-  --------------
-
-  CAN1 and CAN2 are available via RJ-11 connectors on the SAMA4D4-EK.  Each
-  is wired as follows.  Also shown below is the matching pins if you want connect
-  the CAN to a device that uses an DB-9 connector (Such as the IXXAT USB-to-CAN
-  Compact).  Both connector types (as well as RJ-45) are common.

+       for further information.
+
+    3. This configuration executes out of internal SRAM flash and is

+       DataFlash, SD card or from a TFTPC sever via the Boot ROM.
