native-emulation variant does not start, SD card size error

[j0bro]

This is my output, apparently the SD card size is wrong:

qemu-system-aarch64: Invalid SD card size: 1.72 GiB
SD card size has to be a power of 2, e.g. 2 GiB.
You can resize disk images with 'qemu-img resize <imagefile> <new-size>'
(note that this will lose data if you make the image smaller than it currently is).

try

IMAGE="/Users/jeroen/qemu_vms_native/2020-02-13-raspbian-buster-lite.img"; qemu-img resize -f raw "$IMAGE" 2G

I ran into the same issue and the suggested command worked for me. I suppose you could include this command on the scripts, or at least mention this issue on the documentation.

For the record, I’m on macOS Big Sur 11.2.3 running QEMU 5.2.0.

Thanks, @leafac . The resize command is now part of the install script:

macos-qemu-rpi/native-emulation/install.sh

Line 55 in eb0b3d4

qemu-img resize -f raw "${IMAGE}.img" 2G

Great 👍

And thank you for this project. It’s really nice.
