# 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. |
