Building FPGALink & some VHDL examples for Canton Electronics LX9 board on Linux:

# Now from $HOME/20140524/makestuff you now have some useful files:
libs/libfpgalink/firmware/avr/firmware.hex - AVR firmware (assumes at90usb162 with 16MHz crystal)
apps/flcli/lin.x64/rel/flcli - "flcli" binary
apps/gordon/lin.x64/rel/gordon - "gordon" flash tool binary
hdlmake/apps/makestuff/blinky/vhdl/fpga.xsvf - "blinky LEDs" example
hdlmake/apps/makestuff/swled/cksum/vhdl/fpga.xsvf - "cksum example"
hdlmake/apps/makestuff/spi-talk/vhdl/fpga.xsvf - "spi-talk" example


# First load firmware into AVR:
cd libs/libfpgalink/firmware/avr
make dfu

# Next connect TDO->PB3, TDI->PB2, TMS->PB0 and TCK->PB1 and load "blinky" to make two LEDs flash:
flcli -v 1d50:602b:0001 -p J:B3B2B0B1:hdlmake/apps/makestuff/blinky/vhdl/fpga.xsvf

# Next connect EXIO1->PD5, EXIO2->PD3 & EXIO3->PD2 and try "cksum" example:
flcli -v 1d50:602b:0001 -p J:B3B2B0B1:hdlmake/apps/makestuff/swled/cksum/vhdl/fpga.xsvf -c 2 -a 'w0 CAFEBABE;r1;r2' -b

# Finally try reading a few bytes of the onboard flash:
flcli -v 1d50:602b:0001 -p J:B3B2B0B1:hdlmake/apps/makestuff/spi-talk/vhdl/fpga.xsvf
