Integration Tests

Tests for peripherals and other utilities of the riscv-vp.

Dependencies

• riscv-vp binaries must be in $PATH
• GCC cross toolchain (see below)
• GDB with RISC-V support
• CMake

Notes on toolchain

The tests are supposed to work with both RV32 and RV64. As such, testing requires a toolchain for both targets for the riscv-unknown-elf triple with newlib support. The easiest way to build these two toolchains is using the RISC-V riscv-gnu-toolchain repository. Currently, it seems to be necessary to compile desperate compilers for RV32 and RV64. This can be achieved by building a cross toolchain twice.

For RV32:

./configure --prefix=/opt/rv32 --disable-gdb \
	--disable-linux --with-arch=rv32imafdc --with-abi=ilp32

For RV64:

./configure --prefix=/opt/rv64 --disable-gdb \
	--disable-linux --with-arch=rv64imafdc --with-abi=lp64

Afterwards both toolchains have to be added to $PATH, e.g. using:

export PATH="$PATH:/opt/rv32/bin:/opt/rv64/bin"
