+README
+======
+
+ This README provides some information about the port of NuttX to the TI
+ Hercules TMS570LS31x USB Kit featuring the Hercules TMS570LS3137ZWT chip.
+
+Contents
+========
+
+ - Status
+ - Toolchain
+ - LEDs and Buttons
+ - Serial Console
+ - Debugging
+ - Configurations
+
+Status
+======
+
+ 2017-10-18:
+ The basic port to the TMS570 is complete. The NSH with basic commands is
+ up and running. There is support for SCI communication and RTI.
+
+Toolchain
+=========
+
+ Build Platform
+ --------------
+ All of these configurations are set up to build with Ubuntu.
+
+ Endian-ness Issues
+ ------------------
+ I used a version of the NuttX buildroot toolchain that can be built like
+ this:
+
+ cd buildroot/
+ cp configs/cortexr4f-eabi-defconfig-4.8.5 .config
+ make oldconfig
+ make
+
+ Before building the compiler I installed the following packages which
+ are needed for the compiler build.
+
+ # install or update all apt-get dependencies
+ sudo apt-get update
+ sudo apt-get upgrade
+ sudo apt-get install gcc # not cross
+ sudo apt-get install g++
+ sudo apt-get install make
+ sudo apt-get install bison
+ sudo apt-get install flex
+ sudo apt-get install gawk
+ sudo apt-get install libgmp3-dev
+ sudo apt-get install libmpfr-dev libmpfr-doc libmpfr4 libmpfr4-dbg
+ sudo apt-get install mpc
+ sudo apt-get install texinfo # optional
+ sudo apt-get install libcloog-isl-dev # optional
+ sudo apt-get install build-essential
+ sudo apt-get install glibc-devel
+ sudo apt-get -y install gcc-multilib libc6-i386
+
+Serial Console
+==============
+
+ This TMS570ls3137 has a single SCI and one combined SCI/LIN interface.
+ The SCI_RX and TX pins are connected to the FTDI chip which provides a
+ virtual COM port for the usb kit.
+
+Debugging
+=========
+
+ I used the On Board Debugger.
+
+Configurations
+==============
+
+ Information Common to All Configurations
+ ----------------------------------------
+ Each TMS570LS31X Usb Kit configuration is maintained in a sub-directory and
+ can be selected as follow:
+
+ cd tools
+ ./configure.sh tms570ls31x-usb-kit/
+ cd -
+
+ Before building, make sure the PATH environment variable includes the
+ correct path to the directory than holds your toolchain binaries.
+
+ And then build NuttX by simply typing the following. At the conclusion of
+ the make, the nuttx binary will reside in an ELF file called, simply, nuttx.
+
+ make oldconfig
+ make
+
+ The that is provided above as an argument to the tools/configure.sh
+ must be is one of the following.
+
+ NOTES:
+
+ 1. These configurations use the mconf-based configuration tool. To
+ change any of these configurations using that tool, you should:
+
+ a. Build and install the kconfig-mconf tool. See nuttx/README.txt
+ see additional README.txt files in the NuttX tools repository.
+
+ b. Execute 'make menuconfig' in nuttx/ in order to start the
+ reconfiguration process.
+
+Configuration sub-directories
+-----------------------------
+
+ nsh:
+
+ Configures the NuttShell (nsh) located at examples/nsh.

+/* LEDs
+ *
+ * The launchpad has several LEDs:
+ *
+ * - LEd D1 (white) that connects to the USB +5V supply,
+ * - LED D10 (red) that connects to the TMS570's NERROR pin,
+ * - D5 (blue), D6 (blue), and D8 (blue) connect to the XDS100 FT2322,
+ * - D7 (blue) connects to the XSD100 CPLD, and
+ * - Two white, user LEDs labeled D12 that connects to the NHET08
+ * pin and D11 that connects to GIOA2.
+ *
+ * NHET08 is one of 32 N2HET pins than can be available to the user if
+ * not used by N2HET. This implementation, however, uses only the single
+ * LED driven by GIOA2. That LED is tied to ground and illuminated
+ * with a high level output value.
+ *
+ * This LED is not used by the board port unless CONFIG_ARCH_LEDS is
+ * defined. In that case, the usage by the board port is defined in
+ * include/board.h and src/tms570_autoleds.c. The LED is used to encode
+ * OS-related events as follows:
+ *
+ * ------------------- ----------------------- ------
+ * SYMBOL Meaning LED
+ * ------------------- ----------------------- ------
+ * LED_STARTED NuttX has been started OFF
+ * LED_HEAPALLOCATE Heap has been allocated OFF
+ * LED_IRQSENABLED Interrupts enabled OFF
+ * LED_STACKCREATED Idle stack created ON
+ * LED_INIRQ In an interrupt N/C
+ * LED_SIGNAL In a signal handler N/C
+ * LED_ASSERTION An assertion failed N/C
+ * LED_PANIC The system has crashed FLASH
+ *
+ * Thus if the LED is statically on, NuttX has successfully booted and is,
+ * apparently, running normally. If the LED is flashing at approximately
+ * 2Hz, then a fatal error has been detected and the system has halted.

+ * - D5 (blue), D6 (blue), and D8 (blue) connect to the XDS100 FT2322,
+ * - D7 (blue) connects to the XSD100 CPLD, and
+ * - Two white, user LEDs labeled D12 that connects to the NHET08
+ * pin and D11 that connects to GIOA2.
+ *
+ * NHET08 is one of 32 N2HET pins than can be available to the user if not
