- # 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.
