Release notes at: https://github.com/riscv-software-src/opensbi/releases/tag/v1.6 From release notes: "Overall, this release adds more ISA extensions, drivers, and other improvements." This OpenSBI version 1.6 can be tested in qemu with the commands: cat <<EOF >.config BR2_riscv=y BR2_LINUX_KERNEL=y BR2_LINUX_KERNEL_USE_ARCH_DEFAULT_CONFIG=y BR2_TARGET_ROOTFS_EXT2=y BR2_TARGET_OPENSBI=y BR2_TARGET_OPENSBI_PLAT="generic" BR2_TOOLCHAIN_EXTERNAL=y EOF make olddefconfig make Then: qemu-system-riscv64 \ -M virt \ -bios output/images/fw_jump.bin \ -kernel output/images/Image \ -append "rootwait root=/dev/vda ro" \ -drive file=output/images/rootfs.ext2,format=raw \ -nographic Note that in the previous qemu command line, the OpenSBI ".bin" image is passed rather than the ".elf" image. Loading the ".elf" image in qemu can now lead to the following qemu error: qemu-system-riscv64: Some ROM regions are overlapping These ROM regions might have been loaded by direct user request or by default. They could be BIOS/firmware images, a guest kernel, initrd or some other file loaded into guest memory. Check whether you intended to load all this guest code, and whether it has been built to load to the correct addresses. The following two regions overlap (in the memory address space): fw_jump.elf ELF program header segment 1 (addresses 0x0000000000000000 - 0x00000000000271e0) mrom.reset (addresses 0x0000000000001000 - 0x0000000000001028) See: https://github.com/riscv-software-src/opensbi/issues/372 Signed-off-by: Kilian Zinnecker <kilian.zinnecker@mail.de> Tested-by: Julien Olivain <ju.o@free.fr> [Julien: reworded the commit log about testing] Signed-off-by: Julien Olivain <ju.o@free.fr>

OpenSBI aims to provide an open-source and extensible

|
implementation of the RISC-V SBI specification for a platform
|
|
specific firmware (M-mode) and a general purpose OS,
|
|
hypervisor or bootloader (S-mode or HS-mode). OpenSBI
|
|
implementation can be easily extended by RISC-V platform or
|
|
System-on-Chip vendors to fit a particular hadware

configuration.
