Actually I try to emulate a real eMMC. I thought an sdcard would be sufficient, but I'm not sure.
eMMC (Embedded Multi Media Card) has a feature called RPMB (Replay Protected Memory Block). Now if I think more about it I should rephrase the question. How to configure qemu to emulate an eMMC drive? The setup is running on a real hardware, but we want to use qemu for development. The device are expensive and if we can get the setup running on qemu we would be independent to the hardware for development and beside we would safe money.

But if you can I would really recommend not trying to use SD card. Use some other kind of block device -- surely OPTEE has support for other kinds of disk ? thanks -- PMM
