The device worked fine in Ubuntu 18.04 and earlier versions but not in Ubuntu 18.10 Status in QEMU: Confirmed Bug description: ARM PL181 MMC card no longer working in qemu-system-arm in Ubuntu 18.10 The MMC driver code worked fine in Ubuntu 15.10 to 18.04. The command to run qemu-system-arm is qemu-system-arm -M versatilepb -m 256M -sd sdimage -kernel t.bin -serial mon:stdio During SDC initialization, SDC commands 2, 3, 9, 13, 7, 16 all timeout, = which cause subsequent read/write commands 17/24 to fail also. Tried both ARM versatilepb and realview-pb-a8, realview-pbx-a9 boards: all the same. To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1809291/+subscriptions
