hi

How to see waveforms in questasim while running the given testcases. I tried to add the signals to waveform window, but I am not able to do it. Is there any command available?.

Hello,

I'm trying to install PULP-SDK following the instructions provided in GitHub, but I get an error I can't understand and for which I haven't found any solution.

I'm starting from a clean Ubuntu 16.04 install, and the sequence of steps I follow (first I install the riscv gnu toolchain and then the PULP SDK) is:

1 - sudo -s

2 - apt install git python3-pip python-pip gawk texinfo libgmp-dev libmpfr-dev libmpc-dev swig3.0 libjpeg-dev lsb-core doxygen python-sphinx sox graphicsmagick-libmagick-dev-compat libsdl2-dev libswitch-perl libftdi1-dev cmake scons libsndfile1-dev

3 - pip3 install artifactory twisted prettytable sqlalchemy pyelftools openpyxl xlsxwriter pyyaml numpy configparser pyvcd

4 - sudo pip2 install configparser

5 - cd /opt

6 - mkdir riscv

7 - cd riscv

8 - git clone https://github.com/pulp-platform/pulp-ri...-toolchain

9 - cd pulp-riscv-gnu-toolchain

10 - git submodule update --init --recursive

11 - apt-get install autoconf automake autotools-dev curl libmpc-dev libmpfr-dev libgmp-dev gawk build-essential bison flex texinfo gperf libtool patchutils bc zlib1g-dev

12 - export PATH=$PATH:/opt/riscv/bin

13 - ./configure --prefix=/opt/riscv --with-arch=rv32imc --with-cmodel=medlow --enable-multilib

14 - make

15 - export PULP_RISCV_GCC_TOOLCHAIN=/opt/riscv

16 - export VSIM_PATH=/opt/riscv/pulpissimo/sim

17 - cd ..

18 - git clone https://github.com/pulp-platform/pulp-sdk.git -b master

19 - cd pulp-sdk

20 - source configs/pulpissimo.sh

21 - make all

After this last command I get the following error:

Configuring Pulp project at /opt/riscv/pulp-sdk

Following the instructions provided in GitHub I check the versions of both python and pip. What I get is:

root@VBox:/opt/riscv/pulp-sdk# pip --version
pip 19.3.1 from /usr/local/lib/python2.7/dist-packages/pip (python 2.7)
root@VBox:/opt/riscv/pulp-sdk# python3 --version
Python 3.5.2

Then I execute the commands suggested in GitHub:

python3 -m pip install --upgrade pip
python3 -m pip install artifactory twisted prettytable sqlalchemy pyelftools openpyxl xlsxwriter pyyaml numpy configparser pyvcd

However, when I run again 'make all' I get the same error. Since after looking for a solution I haven't found any clue how to fix it, could you provide me any hint to overcome this problem? Thank you very much in advance for your help.

Best regards,

Manuel

Hi,

I have problems using the JTAG debugging connection with GDB for the Ariane Softcore. The Genesys 2 Board is connected to my PC via JTAG. I have OpenOCD with RISC-V support  installed on my machine and it seems to connect just fine:

Hi,

In PULPino environment there are some HEX Files getting generated while i tried to run testcase. So my query is where the conversion from C to HEX file is taking place (code & path). 

thanks in advance.

hi,
 while simulating GPIO in questasim I am getting following error.
please tell me why this occurs and how to resolve it.


thankyou

Hi all, 

First of all, thanks a lot for your help and support.

I was wondering if there is a synthesis - clean version of PULPissimo that's already released to the public. If not, is there any document / way to understand how the clock the distribution is going ? 

What I understand, correct me if I am wrong, that in the case of: 

1- FPGA, u r using a reference clock of 200 MHz to generate two internal clocks by divisions: A- Soc_clk = 20Mhz , B- periph_clk = 10Mhz.

2- In case of the RTL simulation, you r feeding from the TB a reference clock of ~ 32KHz and somehow, using DCO, FLL generating two clocks soc_clk = periph_clk = 17.5 MHz. 

If I am correct, are this on-chip clock generation modules synthesizable? Or they should be mapped to IPs in the PDK ? 

--------- 

Assuming that I want to drive the whole chip using the external clock, is it save to just remove all the " fll, DCO.. etc" modules and pass the signal through the modules to all the system components ? I mean the PAD_xtal_clk, pass it for the fc_subsystem, l2_memory .. etc and the system can work on that clock ? I already did simulation and it worked, but I am making sue that I didn't miss anything as I didn't test the system exhaustively. 

Thanks in advance.

Hi,

I tried to include a new peripheral (PWM) into the PULPino environment, where can I get the library files for that peripheral or it will be auto generated.

Hello! I do the flow according to the Pulpissimo's README.md. But I meet a make error when I execute  the flow at the step "Downloading and running tests ".I change directory to  pulp-rt-examples/hello, and execute make clean all run ，then a "No Such File or Directory" error appears. I cat the Makefile,maybe the PULP_SDK_HOME is undefined. Do I need to set the PULP_SDK_HOME in my .bashrc  manually?

Hi,
I got some errors when build Linux cross-compiler with the following command:
