To give more details this is /usr/lib/u-boot/qemu-riscv64/u-boot.bin. > sha256 of working version of u-boot.bin: > 70f2d929cc60fb9449290a650f62a5ec7d9fdb43db4251a85b294b08d0d7c3d2 > > To get the working version (source code): > https://ftp.denx.de/pub/u-boot/u-boot-2024.01.tar.bz2 > > To get the working version (FreeBSD package): > https://pkg0.tuk.freebsd.org/FreeBSD:14:aarch64/latest/All/u-boot-qemu-riscv64-2024.01.pkg > > I extracted the actual u-boot.bin from FreeBSD for you to try out: > https://www.cons.org/riscv/u-boot.bin > > > Example qemu line showing the problem and solution.

It means that you need to use /usr/lib/u-boot/qemu-riscv64_smode/u-boot.bin instead. The FreeBSD version is also u-boot for running in supervisor mode, that's why it works here. /usr/lib/u-boot/qemu-riscv64/u-boot.bin is for running in machine mode, so using directly -bios /usr/lib/u-boot/qemu-riscv64/u-boot.bin.
