This goes along a small resistor jumper modification and firmware flashing like
it is for the ECP5 board. A warning message is added as the default serial might
be affected (--serial serial by default). The FTDI modification software used
for the ECP5 seems to be requried and matching.
This can be tested this way:
targets/lattice_crosslink_nx_evn.py --csr-csv=csr.csv --toolchain=oxide --programmer=openocd --uart-name crossover+uartbone --build --load
litex_server --uart --uart-port /dev/ttyUSB1
litex_cli --regs
This board is documented as having the LIFCL-40-9BG400C part, but some
versions of the board exist which were fitted with LIFCL-40-8BG400CES,
an engineering sample part. The distinction is important because the
engineering sample requires a different device ID to be embedded in the
bitstream. If you try to build a bitstream for LIFCL-40-9BG400C and load
it onto LIFCL-40-8BG400CES the configuration fails (indicated by the red
"INITN" LED on this board).
Accept --device to allow the user to specify which FPGA part their board
has.
