J-Trace ARM

J-Trace is a JTAG emulator designed for ARM cores which
includes trace (ETM) support. It connects via USB to a PC run-
ning Microsoft Windows 2000 or later. For a complete list of all
operating systems which are supported, please refer to Sup-
ported OS on page 19. J-Trace has a built-in 20-pin JTAG con-
nector and a built in 38-pin JTAG+Trace connector, which are
compatible to the standard 20-pin connector and 38-pin con-
nector defined by ARM.
