# Analog Devices ADSP-SC58x (ARM Cortex-A5 plus one or two SHARC+ DSPs)
# evaluation boards by Analog Devices (and designs derived from them) use a non-standard 10-pin 0.05" ARM Cortex Debug Connector
# pin 9 (GND or GNDDetect) has been usurped with JTAG /TRST
# as a result, a standards-compliant debug pod will only force the processor's debug interface into reset, preventing usage
# so, a connector adapter must be employed on these boards to isolate or otherwise prevent /TRST from being asserted
