Simulating with QEMU¶
Freedom E SDK comes with a number of targets for simulating SiFive RISC-V cores with QEMU, including:
qemu-sifive-e31
qemu-sifive-s51
qemu-sifive-u54
qemu-sifive-u54mc
Building for a QEMU Target¶
Compiling a bare-metal RISC-V program for QEMU targets is much the same as for any other target in Freedom E SDK
make PROGRAM=hello TARGET=qemu-sifive-e31 CONFIGURATION=debug software
One can choose to replace the hello PROGRAM with any other examples,
the debug build CONFIGRATION with the release, and the qemu-sifive-e31`
target with others QEMU like ``qemu-sifive-u54. For example, if you wished to
build the timer-interrupt example for the qemu-sifive-u54mc target using
the release build configuration, you would instead run the command
make PROGRAM=timer-interrupt TARGET=qemu-sifive-u54mc CONFIGURATION=release software
Running in QEMU Simulation¶
Running a program in qemu simulation is as easy as invoking the simulate
make target:
make PROGRAM=hello TARGET=qemu-sifive-e31 CONFIGURATION=debug simulate
Cleaning a Target Program Build Directory¶
The clean target can be used to restore a target program’s directory to a clean state.
make PROGRAM=hello TARGET=qemu-sifive-e31 CONFIGURATION=debug clean
