+README
+======
+
+ This directory holds NuttX board support for the Maxim Integrated
+ MAX32660-EVSYS board. That board features:
+
+ o MAX32660 Microcontroller
+ - Arm Cortex-M4F, 96MHz
+ - 256KB Flash Memory
+ - 96KB SRAM
+ - 16KB Instruction Cache
+ - Two SPIs
+ - Two I2Cs
+ - Two UARTs
+ - 14 GPIOs
+ o DIP Breakout Board
+ - 100mil Pitch Dual Inline Pin Headers
+ - Breadboard Compatible
+ o Integrated Peripherals
+ - Red Indicator LED
+ - User Pushbutton
+ o MAX32625PICO-Based Debug Adapter
+ - CMSIS-DAP SWD Debugger
+ - Virtual UART Console
+
+Contents
+========
+
+ o Serial Console
+ o LEDs and Buttons
+
+Serial Console
+==============
+
+ A VCOM serial console is available. This is provided by UART1 via pins
+ P0.10 and P0.11.
+
+LEDs and Buttons
+================
+
+LEDs
+----
+
+ A single red LED is available driven by GPIO P0.13.
+
+ 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/sam_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.
+
+Buttons
+-------
+
+ An single button is available on GPIO P0.12 for use by software.
