2 # Analog Devices ADSP-SC58x (ARM Cortex-A5 plus one or two SHARC+ DSPs)
5 # Evaluation boards by Analog Devices (and designs derived from them) use a
6 # non-standard 10-pin 0.05" ARM Cortex Debug Connector. In this bastardized
7 # implementation, pin 9 (GND or GNDDetect) has been usurped with JTAG /TRST.
9 # As a result, a standards-compliant debug pod will force /TRST active,
10 # putting the processor's debug interface into reset and preventing usage.
12 # A connector adapter must be employed on these boards to isolate or remap
13 # /TRST so that it is only asserted when intended.
