Untethered lowRISC release · lowRISC
Over the past several months, we’ve been working to provide a standalone or ‘untethered’ SoC. Cores in the original Rocket chip rely on communicating with a companion processor via the host-target interface (HTIF) to access peripherals and I/O. This release removes this requirement, adding an I/O bus and instantiating FPGA peripherals. The accompanying tutorial, written by Wei Song, describes how to build this code release and explains the underlying structural changes. We support both the Xilinx KC705 and the lower-priced Nexys4 DDR development boards. We would gladly welcome assistance in supporting other boards.
I look forward to hearing further progress!
cheers,
