+After a successful build, two files namely **RISCV_VIRT_CODE.fd** and **RISCV_VIRT_VARS.fd** are created.

## Test
Below example shows how to boot openSUSE Tumbleweed E20.
1) RISC-V QEMU pflash devices should be of of size 32MiB.
- `truncate -s 32M Build/RiscVVirtQemu/RELEASE_GCC5/FV/RISCV_VIRT_CODE.fd`
+ `truncate -s 32M RISCV_VIRT_CODE.fd`
- `truncate -s 32M Build/RiscVVirtQemu/RELEASE_GCC5/FV/RISCV_VIRT_VARS.fd`
+ `truncate -s 32M RISCV_VIRT_VARS.fd`
2) Running QEMU
