+# Analog Devices ADSP-SC584-EZBRD evaluation board
+#
+# Evaluation boards by Analog Devices (and designs derived from them) use a
+# non-standard 10-pin 0.05" ARM Cortex Debug Connector.  In this bastardized
+# implementation, pin 9 (GND or GNDDetect) has been usurped with JTAG /TRST.
+#
+# As a result, a standards-compliant debug pod will force /TRST active,
+# putting the processor's debug interface into reset and preventing usage.
+#
+# A connector adapter must be employed on these boards to isolate or remap
+# /TRST so that it is only asserted when intended.
+
+# Analog expects users to use their proprietary ICE-1000 / ICE-2000 with all
+# ADSP-SC58x designs, but this is an ARM target (and subject to the
+# qualifications above) many ARM debug pods should be compatible.

+
+# Analog's silicon supports SWD and JTAG, but their proprietary ICE is limited
+# to JTAG.  (This is presumably why their connector pinout was modified.)
+# SWD is chosen here, as it is more efficient and doesn't require /TRST.
+
+transport select swd
+
+# chosen speed is 'safe' choice, but your adapter may be capable of more
