# The Calypso target is connected to an unbuffered FT2232D adapter
# acting as the JTAG interface following Mother Mychaela's method,
# ADBUS7 is wired to the reset pin on TI's 14-pin connector.
# The present OpenOCD config sets things up to allow scan chain autoprobing
# and manual nSRST manipulation, and nothing more.
