Note:
The JTAG connector X4 only populates phyFLEX-i.MX 6 modules
with a specific order option. We recommend integration of a standard
(2 mm pitch) pin header connector in the user target circuitry to allow
easy program updates via the JTAG interface.

PHYTEC offers a JTAG-Emulator adapter (order code JA-002) for
connecting the phyFLEX-i.MX 6 to a standard emulator. The JTAG-
Emulator adapter extends the signals of the module’s JTAG connector
to a standard ARM connector with 2 mm pin pitch. The JA-002
therefore functions as an adapter for connecting the module’s non-
ARM-compatible JTAG connector X4 to standard Emulator
connectors.
