# 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. 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.
