Pulpissimo-VP

This repo is meant to provide a VP solution for the Pulpissimo chip to quickly develop & test SW. Initially this is forked from TGC-VP project in VP-Vibes.

Quick start

  • you need to have a C++14 capable compiler, make, python, and cmake installed

  • install conan.io (see also http://docs.conan.io/en/latest/installation.html):

    
pip3 install --user conan==1.59.0

    It is advised to use conan version 1.5x or newer. In case of an older version please run

    pip3 install --user --upgrade conan

    Installing conan for the first time you need to create a profile:

    
conan profile create default --detect

  • checkout source from git

    git clone --recursive https://github.com/VP-Vibes/Pulpissimo-VP

  • start an out-of-source build:

    
cd Pulpissimo-VP/

# for Pulpissimo-VP simulation specific changes to `dbt-rise-tgc` submodule, we have to apply a patch
cd tgc-iss/dbt-rise-tgc/src/sysc/
patch < /Pulpissimo-VP/core_complex.patch
cd ../../../../

# now we can build VP
cmake -B build/ -S . -DCMAKE_BUILD_TYPE=Release
cmake --build build/ --target tgc-vp -- -j4

  • run the VP with pre-built firmware [TODO]

To rebuild the firmware you need to install a RISC-V toolchain like https://github.com/riscv/riscv-tools.

Windows/Visual Studio build

TODO

TODO

  • uDMA configuration regs

  • clean up TGC-VP stuff (models, target-SW)

  • SPI-M model in UDMA subsystem

  • I2S model in UDMA subsystem

  • report issue with standalone RDL generator that includes duplicated headers (i2c_channel.h for UDMA) default values? read/write masks? trailing #endif?

  • modification in generated source -> RDL files

  • merge to main/master

  • core-complex patch (i. break in wfi_evt ii. redirect udma::interrupt peripheral mapped calls)

  • use VPVibes::vpvper as submodule

  • rest of SoC peripherals and support

  • testing via FreeRTOS apps

  • is there something useful to merge from Trax-VP (private minres space)?
