Add a `flushall` in crt after main returns - When executing via Cantrip on FPGA, was observing that the `return_code` field would contain the sentinel value set before the call to main. Add a flush before we either ebreak or mpause, so that other cores will never have a reason to see stale data. Change-Id: I57b37fc9b8691d16c340c02bdc39aec1cfdac081
This project contains the BSP to build the SW artifact that can run on the Kelvin core, and integrated as part of the Shodan repository.
The project supports two build systems -- Bazel and CMake -- for OSS integration reasons. Bazel is used by TFLM flow, while CMake is the build system for IREE.
If you get this project from Project Shodan manifest, you are all set. If not, you need to have following projects as well to build the project successfully.
<dir>/cache/toolchain_kelvin
This project needs to be at <dir>/sw/kelvin
.
The project uses Bazel 5.1.1, to align with OpenTitan build system requirements.
bazel build //...
To run the unit tests (with the kelvin_sim ISS) Make sure the Environment variable $ROOTDIR
is set to the root directory of the local repo (or run source build/setup.sh
)
bazel test //...
TODO: Add CMake flow
The binaries can be simulated with the kelvin simulator, located at <dir>/sim/kelvin
.
sim_kelvin <elf location>
Load the generated .bin
binaries to the FPGA emulator/Renode simulator.
