* Description:
|
||||
* This function is called by the OS when one or more
|
||||
* signal handling actions have been queued for execution.
|
||||
* The architecture specific code must configure things so
|
||||
* that the 'sigdeliver' callback is executed on the thread
|
||||
* specified by 'tcb' as soon as possible.
|
||||
*
|
||||
* This function may be called from interrupt handling logic.
|
||||
*
|
||||
* This operation should not cause the task to be unblocked
|
||||
* nor should it cause any immediate execution of sigdeliver.
|
||||
* Typically, a few cases need to be considered:
|
||||
*
|
||||
* (1) This function may be called from an interrupt handler
|
||||
* During interrupt processing, all xcptcontext structures
|
||||
* should be valid for all tasks. That structure should
|
||||
* be modified to invoke sigdeliver() either on return
|
||||
* from (this) interrupt or on some subsequent context
|
||||
* switch to the recipient task.
|
||||
* (2) If not in an interrupt handler and the tcb is NOT
|
||||
* the currently executing task, then again just modify
|
||||
* the saved xcptcontext structure for the recipient
|
||||
* task so it will invoke sigdeliver when that task is
|
||||
* later resumed.
|
||||
* (3) If not in an interrupt handler and the tcb IS the
|
||||
* currently executing task -- just call the signal
|
||||
* handler now.
|
||||
*
|
||||
* Assumptions:

||||
* Called from critical section

|
||||
- 5 Joystick style pushbuttons
|
||||
- 16 GPIO pins on 2 of the PMOD expansion connectors
|
||||
|
||||
Not supported:
|
||||
- VGA display port
|
||||
- 8 digit 7-segement display
|
||||
- SD card slot
|
||||
- SPI FLASH memory (shared with FPGA configuration data).
|
||||
- USB HID (single device) connector serviced by external PIC uC
|
||||
- Non-DDR (older version): 16 MB Cellular SRAM
|
||||
- DDR (newer version): 128 MB DDR2 SDRAM
|
||||
- Microphone
|
||||
- 10/100 Ethernet PHY
|
||||
- 3-Axis accelerometer
|
||||
- Temperature sensor

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 architecture, 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 disable the -Werror flag also:
|
||||
|
||||
cd openocd
|
||||
sed -i.bak '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/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 paths: 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.

||||

||||

||||

||||

||||

|
||||
RX FPGA C4 (USB UART device)
|
||||
TX FPGA D4 (USB UART device)
|
||||
|
||||
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.

|

* sections are inserted in increasing address order according to the
|
||||
* location counter. The following statement will take all of the .bar
|
||||
* input sections and reloate them into the .foo output section which
|
||||
* starts at address 0x1000.
|

*

|

*
|

* If we wrap an input specification with a KEEP command then it
|
||||
* prevents it from being eliminted during "link-time garbage
|
||||
* collection". I'm not sure what this is, so I just followed what was
|
||||
* done in idt32.ld.
|
||||
*
|
||||
* We can also set a global external symbol to a specific address in the
|
||||
* output binary with this syntax:
|
||||
*
|
||||
* _etext = .;
|
||||
* PROVIDE( etext = . );
|
||||
*
|
||||
* This will set the global symbol _ftext to the current location. If we
|
||||
* wrap this in a PROVIDE command, the symbol will only be set if it is
|
||||
* not defined. We do this with symbols which don't begin with an
|
||||
* underscore since technically in ansi C someone might have a function
|
||||
* with the same name (eg. etext).
|
||||
*
|
||||
* If we need to label the beginning of a section we need to make sure
|
||||
* that the linker doesn't insert an orphan section between where we
|
||||
* set the symbol and the actual beginning of the section. We can do that
|
||||
* by assigning the location dot to itself.
