-    4. Kernel Modules
+Configuration sub-directories
+-----------------------------
+
+The <subdir> that is provided above as an argument to the tools/configure.sh
+must be is one of the following.
+
+  knsh:
+
+    This is identical to the nsh configuration below except that NuttX
+    is built as a PROTECTED mode, monolithic module and the user applications
+    are built separately.
+
+    It is recommends to use a special make command; not just 'make' but make
+    with the following two arguments:
+
+        make pass1 pass2
+
+    In the normal case (just 'make'), make will attempt to build both user-
+    and kernel-mode blobs more or less interleaved.  That actual works!
+    However, for me it is very confusing so I prefer the above make command:
+    Make the user-space binaries first (pass1), then make the kernel-space
+    binaries (pass2)
+
+    NOTES:
+
+    1. At the end of the build, there will be several files in the top-level
+       NuttX build directory:
+
+       PASS1:
+         nuttx_user.elf    - The pass1 user-space ELF file
+         nuttx_user.hex    - The pass1 Intel HEX format file (selected in defconfig)
+         User.map          - Symbols in the user-space ELF file
+
+       PASS2:
+         nuttx             - The pass2 kernel-space ELF file
+         nuttx.hex         - The pass2 Intel HEX file (selected in defconfig)
+         System.map        - Symbols in the kernel-space ELF file
+
+       The J-Link programmer will except files in .hex, .mot, .srec, and .bin
+       formats.
+
+    2. Combining .hex files.  If you plan to use the .hex files with your
+       debugger or FLASH utility, then you may need to combine the two hex
+       files into a single .hex file.  Here is how you can do that.
+
+       a. The 'tail' of the nuttx.hex file should look something like this
+          (with my comments added):
+
+            $ tail nuttx.hex
+            # 00, data records
+            ...
+            :10 9DC0 00 01000000000800006400020100001F0004
+            :10 9DD0 00 3B005A0078009700B500D400F300110151
+            :08 9DE0 00 30014E016D0100008D
+            # 05, Start Linear Address Record
+            :04 0000 05 0800 0419 D2
+            # 01, End Of File record
+            :00 0000 01 FF
+
+          Use an editor such as vi to remove the 05 and 01 records.
+
+       b. The 'head' of the nuttx_user.hex file should look something like
+          this (again with my comments added):
+
+            $ head nuttx_user.hex
+            # 04, Extended Linear Address Record
+            :02 0000 04 0801 F1
+            # 00, data records
+            :10 8000 00 BD89 01084C800108C8110208D01102087E
+            :10 8010 00 0010 00201C1000201C1000203C16002026
+            :10 8020 00 4D80 01085D80010869800108ED83010829
+            ...
+
+          Nothing needs to be done here.  The nuttx_user.hex file should
+          be fine.
+
+       c. Combine the edited nuttx.hex and un-edited nuttx_user.hex
+          file to produce a single combined hex file:
+
+          $ cat nuttx.hex nuttx_user.hex >combined.hex
+
+       Then use the combined.hex file with the to write the FLASH image.
+       If you do this a lot, you will probably want to invest a little time
+       to develop a tool to automate these steps.

+/* The STM32F407VG has 1024Kb of FLASH beginning at address 0x0800:0000 and
+ * 192Kb of SRAM. SRAM is split up into three blocks:
+ *
+ * 1) 112KB of SRAM beginning at address 0x2000:0000
+ * 2)  16KB of SRAM beginning at address 0x2001:c000
+ * 3)  64KB of CCM SRAM beginning at address 0x1000:0000
+ *
+ * When booting from FLASH, FLASH memory is aliased to address 0x0000:0000
+ * where the code expects to begin execution by jumping to the entry point in
+ * the 0x0800:0000 address range.
+ *
+ * For MPU support, the kernel-mode NuttX section is assumed to be 128Kb of
+ * FLASH and 4Kb of SRAM.  That is an excessive amount for the kernel which
+ * should fit into 64KB and, of course, can be optimized as needed (See
+ * also configs/stm32f4discovery/scripts/kernel-space.ld).  Allowing the
+ * additional does permit addition debug instrumentation to be added to the
+ * kernel space without overflowing the partition.
+ *
+ * Alignment of the user space FLASH partition is also a critical factor:
+ * The user space FLASH partition will be spanned with a single region of
+ * size 2**n bytes.  The alignment of the user-space region must be the same.
+ * As a consequence, as the user-space increases in size, the alignmment
+ * requirement also increases.
+ *
+ * This alignment requirement means that the largest user space FLASH region
+ * you can have will be 512KB at it would have to be positioned at
+ * 0x08800000.  If you change this address, don't forget to change the
+ * CONFIG_NUTTX_USERSPACE configuration setting to match and to modify
+ * the check in kernel/userspace.c.
+ *
+ * For the same reasons, the maximum size of the SRAM mapping is limited to
+ * 4KB.  Both of these alignment limitations could be reduced by using
+ * multiple regions to map the FLASH/SDRAM range or perhaps with some
+ * clever use of subregions.
+ *
+ * A detailed memory map for the 112KB SRAM region is as follows:
+ *
+ *   0x20000 0000:  Kernel .data region.  Typical size: 0.1KB
+ *   ------- ----   Kernel .bss  region.  Typical size: 1.8KB
+ *   0x20000 0800:  Kernel IDLE thread stack (approximate).  Size is
+ *                  determined by CONFIG_IDLETHREAD_STACKSIZE and
+ *                  adjustments for alignment.  Typical is 1KB.
+ *   ------- ----   Padded to 4KB
+ *   0x20000 1000:  User .data region.  Size is variable.
+ *   ------- ----   User .bss region  Size is variable.
+ *   0x20000 2000:  Beginning of kernel heap.  Size determined by
+ *                  CONFIG_MM_KERNEL_HEAPSIZE.
+ *   ------- ----   Beginning of user heap.  Can vary with other settings.
+ *   0x20001 c000:  End+1 of CPU RAM
