,zba=true,zbb=true ./hello_rv32imac Then you will get the following error message: qemu-riscv32: Zfa extension requires F extension Since Zfa has just been ratified, I suppose disabling it by default makes sense and will not break anything that exists. Best Regards, Jerry ZJ SiFive Inc. Taiwan

=true, Zicsr=true, Zifencei=true, zba=true, zbb=true, the QEMU will have the following error. Zfa extension requires F extension IMHO, we should not enable Zfa extension by default, especially when Zfa requires F to be enabled implicitly. Best Regards, Jerry ZJ SiFive Inc. Taiwan On Nov 6, 2023 at
