Microbit programs are typically in Intel HEX (.hex) format. The generic loader supports .hex files but it doesn't work as expected: $ qemu-system-arm -M microbit -device loader,file=microbit.hex Guest image must be specified (using -kernel) This error comes from armv7m_load_kernel(). Don't try to use it. Note that we need to register the reset handler that armv7m_load_kernel() used to register for us.
