This is a port of the OpenCores adv_jtag_bridge to support the RISC-V adv_dbg_sys port, which can also be found on RoaLogic github.
Building instructions:
./autogen.sh
./configure
./make
To support the ft254 (Altera USB Blaster) make sure to install libusb and libftdi. Currently the core only supports the pre 1.0 releases. So make sure to install the correct version.
