I am using the following command to boot a Linux v5.11 kernel, but it hangs at: $ qemu-system-riscv64 -M sifive_u -smp 5 -m 8G -display none -serial stdio -kernel arch/riscv/boot/Image -dtb arch/riscv/boot/dts/sifive/hifive-unleashed-a00.dtb -append "earlycon=sbi console=ttySIF0" [ 0.000000] smp: Bringing up secondary CPUs ... Removing -dtb makes the kernel continue booting. I am not sure what's missing ofusing "-dtb"? Regards, Bin
