Yes, that way works:
$ qemu-system-arm -drive if=mtd,file=tmp.qcow2,readonly
qemu-system-arm: -drive if=mtd,file=tmp.qcow2,readonly: readonly not
supported by this bus type
But try this way:
$ qemu-system-arm -drive if=none,file=tmp.qcow2,readonly,id=foo -device
nand,drive=foo
Kernel image must be specified
Grr, force it:
$ qemu-system-arm -drive if=none,file=tmp.qcow2,readonly,id=foo -device
nand,drive=foo -kernel /dev/null
qemu: hardware error: nand_device_init: Unsupported NAND block size.
[...]
Note that I didn't bother supplying a drive with sensible size. If I
did, I guess I'd get nand coupled to a read-only drive. Easy enough for
you to try :)
