-  Enabling Support for the DFU Bootloader
+  The Nucleo-F401RE includes boot loader from mbed:
-  --------------------------------------
-  The linker files in these projects can be configured to indicate that you
-  will be loading code using STMicro built-in USB Device Firmware Upgrade (DFU)
-  loader or via some JTAG emulator.  You can specify the DFU bootloader by
-  adding the following line:
 
-    CONFIG_STM32_DFU=y
+    https://mbed.org/platforms/ST-Nucleo-F401RE/
+    https://mbed.org/handbook/Homepage
 
-  to your .config file. Most of the configurations in this directory are set
+  Using the mbed loader:
-  up to use the DFU loader.
 
-  If CONFIG_STM32_DFU is defined, the code will not be positioned at the beginning
+  1. Connect the Nucleo-F401RE to the host PC using the USB connector.
-  of FLASH (0x08000000) but will be offset to 0x08005000.  This offset is needed
+  2. A new file system will appear called NUCLEO; open it with Windows
-  to make space for the DFU loader and 0x08005000 is where the DFU loader expects
+     Explorer (assuming that you are using Windows).
-  to find new applications at boot time.  If you need to change that origin for some
+  3. Drag and drop nuttx.bin into the MBED window.  This will load the
-  other bootloader, you will need to edit the file(s) ld.script.dfu for the
+     nuttx.bin binary into the Nucleo-F401RE.  The NUCLEO window will
-  configuration.
+     close then re-open and the Nucleo-F401RE will be running the new code.
-
-  For Linux or Mac:
-  ----------------
-
-  While on Linux or Mac,
-
-  $ lsusb
-  Bus 003 Device 061: ID 0483:374b STMicroelectronics
-
-  $ st-flash write nuttx.bin 0x08000000
-
-  Enabling JTAG
-  -------------
-  If you are not using the DFU, then you will probably also need to enable
-  JTAG support.  By default, all JTAG support is disabled but there NuttX
-  configuration options to enable JTAG in various different ways.
-
-  These configurations effect the setting of the SWJ_CFG[2:0] bits in the AFIO
-  MAPR register.  These bits are used to configure the SWJ and trace alternate function I/Os.
-  The SWJ (SerialWire JTAG) supports JTAG or SWD access to the Cortex debug port.
-  The default state in this port is for all JTAG support to be disable.
-
-  CONFIG_STM32_JTAG_FULL_ENABLE - sets SWJ_CFG[2:0] to 000 which enables full
-    SWJ (JTAG-DP + SW-DP)
-
-  CONFIG_STM32_JTAG_NOJNTRST_ENABLE - sets SWJ_CFG[2:0] to 001 which enable
-    full SWJ (JTAG-DP + SW-DP) but without JNTRST.
-
-  CONFIG_STM32_JTAG_SW_ENABLE - sets SWJ_CFG[2:0] to 010 which would set JTAG-DP
-    disabled and SW-DP enabled
-
-  The default setting (none of the above defined) is SWJ_CFG[2:0] set to 100
-  which disable JTAG-DP and SW-DP.
