 GoodFET Firmware

+and some damned good neighbors.
 
-Requires MSPGCC and msp430-bsl.
+Set $GOODFET to be the port of your GoodFET, such as
+export GOODFET=/dev/cu.usbserial-*      #Darwin
+export GOODFET=/dev/ttyUSB*             #Linux (Default)
 
-Assumes MSP430F161x by default.  Call for others by
-mcu=msp430x2618 make -e
+The target board must be specified.  For example,
+board=goodfet31 make clean install
+board=goodfet41 make clean install
+board=telosb make clean install
 
+We require at least msp430-gcc-4.4.5, but older versions might work if
+you're lucky.
+
+For faster startup times, it helps to write a static clock
+configuration into the firmware.  In the following example, the proper
+DCO happens to be 0x8F8A.
+
+pro% goodfet.monitor info
+GoodFET with f26f MCU
+Clocked at 0x8f8a
+pro% board=goodfet41 CFLAGS='-DSTATICDCO=0x8f8a' make clean install
