# Currently there are following board variants:
|
||
|
|
# CS-ULX3S-01 - LFE5U 12F
|
||
|
|
# CS-ULX3S-02 - LFE5U 45F
|
||
|
|
# CS-ULX3S-03 - LFE5U 85F
|
||
|
|
#
|
||
|
|
# two JTAG interfaces:
|
||
|
|
# - US1, micro USB port connected to FT231XQ
|
||
|
|
# This interface should be used with following config:
|
||
|
|
# interface/ft232r/radiona_ulx3s.cfg
|
||
|
|
# - J4, 6 pin connector
|
||
|
|
#
|
||
|
|
# Both of this interfaces share the JTAG lines (TDI, TMS, TCK, TDO) between
|
||
|
|
# Lattice ECP5 FPGA chip and ESP32 WiFi controller.
|
||
|
|
# Note: TRST_N of the ESP32 is pulled up by default and can be pulled down over
|
||
|
|
# J3 interface.
