What would one need to do to get this running on BlackIce II board?

Hi,

You'll need to create a new .mk and .pcf file in the boards directory - it's probably easiest to base these on the existing files.

Based on the information available at https://www.tindie.com/products/Folknology/blackice-ii/, the variables in the .mk file should be set to:

SPEED should be set to hx.
DEVICE should be set to 8k. (Although the BlackIce II has a 4k part, the 4k and 8k parts are the same internally.)
PACKAGE should be set to tq144:4k.
FREQ_OSC should be set to 100.

Based on the schematics and https://github.com/mystorm-org/BlackIce-II/blob/master/examples/common/blackice-ii.pcf, the pin mappings in the .pcf file should be set as follows:

clk should be set to 129.
leds[0], leds[1], leds[2] and leds[3] should be set to 71, 67, 68 and 70. The remaining four led outputs can be set to any unused pin (selecting the pins connected to an unused PMOD connector is probably a good choice).
flash_* are currently unused and can be set to any unused pin (again, using an unused PMOD connector is probably a good choice). I'm not sure if the BlackIce II has an SPI flash chip connected directly to the FPGA, so this might need thinking about when SPI flash support is added.
uart_rx should be set to 88.
uart_tx should be set to 85.

Then follow the instructions in the README, setting BOARD to the name you chose (e.g. BOARD=xyz will use boards/xyz.mk and boards/xyz.pcf).

I don't have a BlackIce II board, so all of the above is completely untested - so please check carefully before trying it in case I've made a mistake that will damage your board!

If you get it working I'd be happy to accept a PR :)

Closing as PR #3 has been merged, thanks :)
