PHYTEC offers a JTAG-Emulator adapter (order code JA-002) for connecting the phyCORE-i.MX27
to a standard emulator. The JTAG-Emulator adapter extends the signals of the module's JTAG
connector to a standard ARM connector with 2.54 mm pin pitch. The JA-002 therefor functions as an
adapter for connecting the module's non-ARM-compatible JTAG connector U15 to standard Emulator
connectors.
