The Stratix device’s JTAG pins can also be accessed via the Mictor
connector (J25). The pins of J24 are connected directly to pins on J25, and
care must be taken so that signal contention does not occur between the
two connectors.
JTAG Connector to EPM7128AE Device (J5)
J5 connects to the JTAG pins (TCK, TDI, TDO, TMS, TRST) of the
EPM7128AE device (U3). Altera Quartus II software can perform in-
system programming (ISP) to reprogram the EPM7128AE device (U3)
with a new hardware image via an Altera download cable.
1 Note that the orientation of J5 is rotated 180
°
compared to J24.
