+# ECPIX-5 85F - LFE5UM5G-85F
+#
+# This boards have two JTAG interfaces:

+#        ADBUS1 TDI

+#        ADBUS3 TMS
+#        BDBUS0 UART_TXD
+#        BDBUS1 UART_RXD
+#   This interface should be used with following config:
+#        interface/ftdi/lambdaconcept_ecpix-5.cfg
+# - CN3, 6 pin connector
+# See schematics for more details:
+# http://docs.lambdaconcept.com/ecpix-5/_static/resources/SCH_ECPIX-5_R02.PDF
+#
+# No reset lines are implemented. So it is not possible to remote reset the FPGA
+# by using any of this interfaces
