QEMU SiFive Unleashed Machine
|
|
=============================
|
|
|
|
The **QEMU SiFive Unleashed Machine** is an emulation of
|
|
SiFive Unleashed platform.
|
|
|
|
To build platform specific library and firmwares, provide
|
|
`PLATFORM=qemu/sifive_u` parameter to top-level make.
|
|
|
|
Platform Options
|
|
----------------
|
|
|
|
We don't have any platform specific options for this platform.
|
|
|
|
Try on QEMU RISC-V 64bit
|
|
------------------------
|
|
|
|
**No Payload**
|
|
|
|
*Build*:
|
|
```
|
|
make PLATFORM=qemu/virt
|
|
```
|
|
*Run*:
|
|
```
|
|
qemu-system-riscv64 -M sifive_u -m 256M -display none -serial stdio -kernel build/platform/qemu/sifive_u/firmware/fw_payload.elf
|
|
```
|
|
|
|
**U-Boot Payload**
|
|
|
|
*Note*: We assume that U-Boot is compiled using `qemu-riscv64_smode_defconfig`.
|
|
|
|
*Build*:
|
|
```
|
|
make PLATFORM=qemu/virt FW_PAYLOAD_PATH=<uboot_build_directory>/u-boot.bin
|
|
```
|
|
*Run*:
|
|
```
|
|
qemu-system-riscv64 -M sifive_u -m 256M -display none -serial stdio -kernel build/platform/qemu/sifive_u/firmware/fw_payload.elf
|
|
or
|
|
qemu-system-riscv64 -M sifive_u -m 256M -display none -serial stdio -kernel build/platform/qemu/sifive_u/firmware/fw_jump.elf -device loader,file=<uboot_build_directory>/u-boot.bin,addr=0x80200000
