Development Environment
|
|
=======================
|
|
The NR5M100 RISC-V core was designed as a low gate count / low performance micro controller
|
|
for inclusion in an ASIC. It is based on a Verilog RISC-V called picorv32, but has many
|
|
additions beyond that baseline. The design running on the Digilent Nexys4 FPGA is a
|
|
validation platform for the core and is presented as an open source project.
|
|
|
|
The reason NR5M100 is "low performance" is that it is a state machine based core (like the
|
|
picorv32) and not a multi-stage pipeline core. This means that it requires an average of
|
|
4.5 clock cycles to execute each instruction. On a multi-stage pipeline architecure, this
|
|
average would be closer to 1 clock cycle per instruction (though a bit higher due to
|
|
pipeline branch misses). The tradeoff for lower performance is a simpler design. There
|
|
is a single memory bus interface for both instructions and data. Multi-stage pipeline
|
|
cores require a separate I and D bus with cache SRAM and an external memory cache controller,
|
|
etc. This in addition to the pipeline registers adds additional gate count.
|
|
|
|
The nr5m100-nexys4 core runs at 83.333 Mhz which provides about 18 Mhz effective operating
|
|
speed with the multi-clock per instruction architecture. If you are looking for a higher
|
|
performance platform, you should check out the PULP Platform ( http://www.pulp-platform.org ).
|
|
That is an FPGA design with a 4-stage pipeline RISC-V core, though not currently supported
|
|
by NuttX. The NR5M100 project will likely pull in the RISC-V core from that design next,
|
|
though this will probably not be available soon. With a bit of work, it is possible to
|
|
run the nr5m100-nexys4 core at 170 Mhz with a 6.5 clocks-per-instruction state machine.
|
|
This would give an effective performance of about 26Mhz.
|
|
|
|
Development Environment
|
|
=======================
|
|
|
|
Linux is the best choice for development, though Cygwin on Windows may work.
|
|
The source has been built only using the GNU toolchain (see below) under a Linux
|
|
environment. Other toolchains will likely cause problems or not be available yet.
|
|
|
|
RISC-V GNU Toolchain
|
|
====================
|
|
|
|
To compile the code, you must first build a RISC-V GNU Toolchain from the sources at
|
|
https://github.com/riscv/riscv-gnu-toolchain. I don't know of any sources for pre-compiled
|
|
toolchains (though there may be some out there).
|
|
|
|
To build this toolchain, follow these instructions (tested on Ubuntu 12.04):
|
|
|
|
1. Create a working directory in your home folder:
|
|
|
|
mkdir ~/riscv
|
|
cd ~/riscv
|
|
|
|
2. Clone the GNU source tree:
|
|
|
|
git clone --recursive https://github.com/riscv/riscv-gnu-toolchain
|
|
|
|
3. Ensure the following packages are installed:
|
|
|
|
sudo apt-get install texinfo bison flex autoconf automake libgmp-dev libmpfr-dev libmpc-dev
|
|
|
|
4. Configure and build the toolchain:
|
|
|
|
cd riscv-gnu-toolchain
|
|
./configure --with-xlen=64 --with-arch=I --disable-float --disable-atomic --enable-multilib --prefix=~/riscv
|
|
make -j4 (or -j8 based on how many cores you have)
|
|
|
|
5. Setup your PATH environment variable to include the toolchain (you may want to add this to
|
|
your shell login script, such as .bash_profile, etc.):
|
|
|
|
export PATH=~/riscv/bin:$PATH
|
|
|
|
Windows based toolchain
|
|
-----------------------
|
|
May be possible to compile the GNU toolchain described above using Cygwin, but havne't tried it.
|
|
|
|
Debugger
|
|
========
|
|
The Debug Module within the NR5M100 RISC-V has been designed to work with the RISC-V gdb
|
|
debugger interfaced with the SiFive implementation of OpenOCD. The interface has been tested
|
|
with a J-LINK JTAG probe connected to PMOD header B on the FPGA using an adapter board
|
|
that I designed and fabbed at OSHPark. I will update this README.txt file soon with a link
|
|
to the shared project for anyone who wishes to build one.
|
|
|
|
To build OpenOCD, perform the following:
|
|
|
|
1. Ensure the proper packages are installed:
|
|
|
|
sudo apt-get install autoconf automake libtool libusb-1.0-0-dev
|
|
|
|
2. Download the latest OpenOCD sources from the SiFive github repo:
|
|
|
|
cd ~/riscv
|
|
git clone --recursive https://github.com/sifive/openocd.git
|
|
|
|
3. Configure and build OpenOCD. The x86_64 GCC compilers will give errors because of
|
|
shadowed variable warnings, so diable the -Werror flag also:
|
|
|
|
cd openocd
|
|
sed -i 's/ -Werror//g' configure.ac
|
|
./bootstrap
|
|
./configure --enable-jlink --enable-maintainer-mode --enable-ftdi --prefix=~/riscv CFLAGS=-g
|
|
|
|
The configuration scripts for openocd and nr5m100-nexys4 have been provided in the
|
|
nuttx/boards/nr5m100-nexys4/scripts directory. They are configured to use a J-LINK JTAG
|
|
probe and to search for the IQ-Analog (the company I work for) IDCODE and part number for
|
|
the FPGA board (7a10 for Artix xc7a100 part on the Digilent Nexys4 board). With FPGA
|
|
source directly from the nr5m100 github site (to be provided), this ID will match the
|
|
hardware. If changes are made to the JEDEC ID and/or part number, then the nr5m100.cfg
|
|
file will need to be modified with the proper CPUID value.
|
|
|
|
IDEs
|
|
====
|
|
|
|
NuttX is built using command-line make. It can be used with an IDE, but some
|
|
effort will be required to create the project. While I haven't tried it as
|
|
I am not an IDE guy, the team at SiFive have reported that they now have
|
|
Eclipse working with the RISC-V gdb debugger.
|
|
|
|
NOTE: The notes below are taken from an ARM build of NuttX, not RISC-V, so
|
|
they may or may not work. Try it and see I suppose.
|
|
|
|
Makefile Build
|
|
--------------
|
|
Under Eclipse, it is pretty easy to set up an "empty makefile project" and
|
|
simply use the NuttX makefile to build the system. That is almost for free
|
|
under Linux. Under Windows, you will need to set up the "Cygwin GCC" empty
|
|
makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
|
|
there is a lot of help on the internet).
|
|
|
|
Native Build
|
|
------------
|
|
Here are a few tips before you start that effort:
|
|
|
|
1) Select the toolchain that you will be using in your .config file
|
|
2) Start the NuttX build at least one time from the Cygwin command line
|
|
before trying to create your project. This is necessary to create
|
|
certain auto-generated files and directories that will be needed.
|
|
3) Set up include pathes: You will need include/, arch/risc-v/src/rv32im,
|
|
arch/risc-v/src/common, arch/risc-v/src/nr5m100, and sched/.
|
|
4) All assembly files need to have the definition option -D __ASSEMBLY__
|
|
on the command line.
|
|
|
|
Startup files will probably cause you some headaches. The NuttX startup file
|
|
is arch/risc-v/src/nr5m100/nr5_vectors.S. With RIDE, I build NuttX
|
|
one time from the Cygwin command line in order to obtain the pre-built
|
|
startup object needed by RIDE.
|
|
|
|
LEDs
|
|
====
|
|
|
|
The Nexys4 board has 16 single-color LEDs onboard, as well as 2 tri-color LEDs.
|
|
These are supported using GPIO Ports A (16-single color) and B (tri-color).
|
|
Additionally the tri-color LEDs can be driven from the Timer 1 or 2 PWM output
|
|
signals.
|
|
|
|
PWM
|
|
===
|
|
|
|
The nr5m100-nexys4 design has PWM capabilities within the Timer 1 and Timer 2
|
|
modules. These PWM signals can be muxed to the tri-color LEDs or to I/O
|
|
pins on one of the PMOD expansion headers.
|
|
|
|
UARTs
|
|
=====
|
|
|
|
The nr5m100-nexys4 design has an onboard USB-UART providing an RS-232 interface
|
|
via the same USB cable that is used to program the FPGA. The core proivdes a
|
|
fixed 8-Data bit, 1 stop bit, no parity UART connected to this intrface.

Default USART/UART Configuration
|
|
--------------------------------
|
|
|
|
UART1 is enabled in all configurations (see */defconfig).
|
|
|
|
Configurations
|
|
==============
|
|
|
|
Each nr5m100-nexys4 configuration is maintained in a sub-directory and
|
|
can be selected as follow:
|
|
|
|
tools/configure.sh nr5m100-nexys4:<subdir>
|
|
|
|
Where <subdir> is one of the following:
|
|
|
|
nsh
|
|
---
|
|
This is an NSH example that uses UART1 as the console. UART1 is connected
|
|
to the USB UART bridge on the FPGA board.
