As far as I understand it you can use a programming cable to run ET bitstream already and there is even a chance our front end might just work anyway. Urjtag has support for a FT2232 a very close relative of the FT4232 we use on Cairnsmore1.
Which cable do I need? Your prog3 cable? Is it supported by urjtag?
We have not proven either hardware with urjtag. Our Prog3 is a Xilinx cable clone and in theory would work urjtag as Xilinx cable is on the support list. That said there are a range of Xilinx cables and it is possible our clone is one not supported. We know Prog3 works fully with Xilinx tools and that has always been our benchmark.
The in-built FT4232 on Cairnsmore1 is a big brother version of the FT2232 that is on the urjtag support list. It has the same JTAG processing features so that is why it might work.
speaking of ROI, DHL just called me and they said customs wants 400$ some dollars before they can release the shipment. Maybe I should have looked this up but I guess import tax is applied to more expensive shipments in the US?
This one is always difficult to give a number on because every country is different and the tariff code that things ship under changes it as well even for a single country. There are tools on the courier websites but even then those are difficult to use and predict charges. As we ship to over 30 countries, and 30 different taxation and customs regulations, on a regular basis we gave up years ago trying to work out these potential taxes and duties and we always quote as local taxes and duties may apply.
Local/federal sales tax is often collected in many countries so you don't avoid that by importing. I know about the states side fiddle of buying in another state and then not doing a proper declaration of what you owe in sales tax and people do do that. However some states are now very hot on that now and they are coming down hard on tax avoiders. On low value items most countries just wave the sales tax bit as processing is more expensive than the tax. I think here it is about £20 for that threshold.
The one that varies is most is duties and that very much depends on what the item is. Trying to allocate a harmonised code that this all hangs on is incredibly hard. The lists tend to be 5 years behind real items never mind niche items like Cairnsmore1. The US did have a different tax called MFP but it was very low percentage and we never have seen it appied.
