Please check the commit message of: [18/22] hw/riscv: sifive_u: Add QSPI2 controller and connect an SD card The command should be: $ qemu-system-riscv64 -nographic -M sifive_u,msel=11 -smp 5 -m 8G \ -bios u-boot-spl.bin -drive file=sdcard.img,if=sd Note the memory should be 8G and the SD card is already connected by the sifive_u machine codes.
