I am trying to develop custom firmware for the Texas Instruments TSW14J56 Data Capture Board, which utilizes an Altera Arria V GZ FPGA. TI provides the firmware on their website (http://www.ti.com/tool/tsw14j56evm) in the form of a quartus project. Attempting to open this project in Quartus Prime 17.1 results in a ton of errors of the form "Can't create file (...) because path exceeds 260 character limit." Most of the path length comes from the path internal to the project, that I cannot modify, and the project (with this long path), must have been created in Quartus. I have ensured that my windows registry has long paths enabled, but the issue persists.
260 character limit is a windows limit, not a quartus one. It was probably created on the linux version of quartus.If you cannot install linux, try running on a virtual PC.
