Also, 'u-boot' is an ELF file. At least in the instructions today[2] we use the flat binary produced from that ELF: qemu-system-arm64 -M raspi3b -kernel u-boot.bin But that doesn't work either. So I'm not sure how to make it work. If you do figure it out, a documentation patch for U-Boot Regards, Simon > > best, > jack [1] https://www.qemu.org/docs/master/system/arm/raspi.html [2] https://docs.u-boot.org/en/latest/board/emulation/qemu-arm.html#running-u-boot
