Mounting an sdcard on x86?

[Norbert Lange]

Hello,

I am trying to bot a kernel/initramfs combo, the kernel is customized
for Intels Apollo Lake, and does not contain the normal sata/ide
kernel modules, as it boots from eMMC.

I cant manage to tell Qemu to hook an SD device to the Emulation,
closest I got is with
"-device sd-card -drive file=/tmp/image.bin,format=raw,if=sd"

but that fails: "qemu-system-x86_64: -device sd-card: No 'sd-bus' bus
found for device 'sd-card'"

Version is:
QEMU emulator version 4.2.0 (Debian 1:4.2-1)
