Can't use flash on Mac (dd: invalid number: ‘1m’) #131

Closed ghost closed 5 years ago

ghost commented 6 years ago

When using flash on my Mac I just get a dd error message.

Is this a bug in the script or am I doing something wrong?

flash --bootconf config.txt --userdata cloud-init.yml hypriotos-rpi-v1.9.0.img.zip
Using cached image /tmp/hypriotos-rpi-v1.9.0.img

Is /dev/disk2 correct? y
Unmounting /dev/disk2 ...
Unmount of all volumes on disk2 was successful

@ofcourseican Which version of macOS are you running? What version of dd are you running? Do you have the stock dd? What says which dd?

For me flash works with 10.13.5 and the stock dd (from /bin/dd)

/usr/local/opt/coreutils/libexec/gnubin/dd

So my guess is that brew installed this.

Yes, look like the coreutils formula installs another dd. I tried it in a fresh macOS environment, but I still get the official /bin/dd as result from a which dd. Deep in the cellar I can find /usr/local/Cellar/coreutils/8.30/libexec/gnubin/dd. But it is not in PATH.

You probably should clean up your brew installation.

StefanScherer commented 5 years ago

Only idea that could make it into the flash script is using /bin/dd with absolute path to stick to the official Mac binary.
