I. Keystone

Note: because their prebuilt toolchain is RV64GC, so for the RV32GC or RV32IMAC build we’ll using our local toolchain only.

Git clone:

If build for RV32GC:
$ git clone -b dev-rv32-cmake https://github.com/thuchoang90/keystone.git keystone-rv32gc
$ cd keystone-rv32gc/

If build for RV32IMAC:
$ git clone -b dev-rv32-cmake https://github.com/thuchoang90/keystone.git keystone-rv32imac
$ cd keystone-rv32imac/

Check PATH:

$ echo ${PATH}    #check if our toolchain is on the PATH or not

If not then export it to PATH:
If build for RV32GC:      $ export RISCV=/opt/GCC8/riscv32gc      #point to RV32GC toolchain
If build for RV32IMAC:    $ export RISCV=/opt/GCC8/riscv32imac    #point to RV32IMAC toolchain

Finally:
$ export PATH=$RISCV/bin/:$PATH
$ export KEYSTONE_DIR=`pwd`
$ export KEYSTONE_SDK_DIR=`pwd`/sdk

Update submodule:

$ ./fast-setup.sh   #this time, it won't download the prebuilt toolchain, just update the submodule

$ make -C sdk       #make sdk
$ export EYRIE_DIR=`pwd`/sdk/rts/eyrie
$ ./sdk/scripts/init.sh --runtime eyrie --force

Create build folder:

$ mkdir build
$ cd build/

Make:

$ cmake .. -DRISCV32=y
$ make -j`nproc`

Build the keystone-test:

$ sed -i 's/size_t\sfreemem_size\s=\s48\*1024\*1024/size_t freemem_size = 2*1024*1024/g' ../sdk/examples/tests/test-runner.cpp
  #this line is for FPGA board, because usually there is only 1GB of memory on the board
$ make run-tests    #after this, a bbl.bin file is generated
