Hello Simon,

The qemu-riscv32_spl_defconfig image built inside Docker with

wget -O -
https://github.com/riscv/opensbi/releases/download/v0.9/opensbi-0.9-rv-bin.tar.xz
export
OPENSBI=/tmp/opensbi-0.9-rv-bin/share/opensbi/ilp32/generic/firmware/fw_dynamic.bin
tools/buildman/buildman -o build -w -E -W -e --board qemu-riscv32_spl

runs flawlessly on Ubuntu Jammy with:

qemu-system-riscv32 -nographic -machine virt -bios spl/u-boot-spl \
     -device loader,file=u-boot.itb,addr=0x80200000 -smp cpus=4

This is a QEMU 6.0

Please, provide a reproducible instruction for your problem.

Best regards

Heinrich
