+Creating and Using NORBOOT
+==========================
+
+ In order to have more control of debugging code that runs out of NOR FLASH,
+ I created the sama5d3x-ek/norboot configuration. That configuration is
+ described below under "Configurations."
+
+ Here are some general instructions on how to build an use norboot:
+
+ Building:
+ 1. Remove any old configurations (if applicable).
+
+ cd
+ make distclean
+
+ 2. Install and build the norboot configuration:
+
+ cd tools
+ ./configure.sh sama5d3x-ek/
+ cd -
+ . ./setenv.sh
+
+ Before sourcing the setenv.sh file above, you should examine it and
+ perform edits as necessary so that TOOLCHAIN_BIN is the correct path
+ to the directory than holds your toolchain binaries.
+
+ 3. Rename the binaries. Since you will need two versions of NuttX: this
+ norboot version that runs in internal SRAM and another under test in
+ NOR FLASH, I rename the resulting binary files so that they can be
+ distinguished:
+
+ mv nuttx norboot
+ mv nuttx.hex norboot.hex
+ mv nuttx.bin norboot.bin
+
+ 4. Build your NOR configuration and write this into NOR FLASH. Here, for
+ example, is how you would create the NSH NOR configuration:
+
+ cd
+ make distclean # Remove the norboot configuration
+ cd tools
+ ./configure.sh sama5d3x-ek/nsh # Establish the NSH configuration
+ cd -
+ make # Build the NSH configuration
+
+ Then use SAM-BA to write the nuttx.bin binary into NOR FLASH. This
+ will involve holding the CS_BOOT button and power cycling to start
+ the ROM loader. The SAM-BA serial connection will be on the device
+ USB port, not the debug USB port. Follow the SAM-BA instruction to
+ write the nuttx.bin binary to NOR FLASH.
+
+ 5. Restart the system without holding CS_BOOT to get back to the normal
+ debug setup.
+
+ 6. Then start the J-Link GDB server and GDB. In GDB, I do the following:
+
+ (gdb) mon reset # Reset and halt the CPU
+ (gdb) load norboot # Load norboot into internal SRAM
+ (gdb) mon go # Start norboot
+ (gdb) mon halt # Break in
+ (gdb) mon reg pc = 0x10000040 # Set the PC to NOR flash entry point
+ (gdb) mon go # And jump into NOR flash
+
+ The norboot program can also be configured to jump directly into
+ NOR FLASH with out requiring the the final halt and go, but since I
+ have been debugging the early boot sequence, the above sequence has
+ been most convenient for me.
+
+ STATUS:
+ 2013-7-30: I have been unable to execute this configuration from NOR
+ FLASH by closing the BMS jumper (J9). As far as I can tell, this
+ jumper does nothing on my board??? So I have been using the norboot
+ configuration exclusively to start the program-under-test in NOR FLASH.
