The NOEL-V is a synthesizable VHDL model of a processor that +implements the RISC-V architecture. It is part of the open source +`GRLIB <https://gaisler.com/grlib>`_ IP Library. The following BSP +variants correspond to common NOEL-V configurations: + +* noel32im + +* noel32imafd + +* noel64imac + +* noel64imafd + +* noel64imafdc + +The start of the memory is set to 0x0 to match a standard NOEL-V system, +but can be changed using the ``RISCV_RAM_REGION_BEGIN`` configuration +option. The size of the memory is taken from the information available +in the device tree. + +Reference Designs +----------------- + +The BSP has been tested with NOEL-V reference designs for +`Digilent Arty A7 <https://gaisler.com/noel-artya7>`_, +`Microchip PolarFire Splash Kit <https://gaisler.com/noel-pf>`_, +and `Xilinx KCU105 <https://gaisler.com/noel-xcku>`_. +See the accompanying quickstart guide for each reference design +to determine which BSP configuration to use. + +Build Configuration Options +--------------------------- + +The following options can be used in the BSP section of the ``waf`` +configuration INI file. The ``waf`` defaults can be used to inspect the values. + +``BSP_CONSOLE_USE_INTERRUPTS`` + Use the Termios interrupt mode in the console driver (true by default). + +``BSP_FDT_BLOB_SIZE_MAX`` + The maximum size of the device tree blob in bytes (262144 by default). + +``RISCV_CONSOLE_MAX_APBUART_DEVICES`` + The maximum number of APBUART devices supported by the console driver + (2 by default). + +``RISCV_RAM_REGION_BEGIN`` + The begin of the RAM region for linker command file (0x0 by default). + +``RISCV_MAXIMUM_EXTERNAL_INTERRUPTS`` + The maximum number of external interrupts supported by the BSP (64 by + default). + griscv ====== |
