I am trying to build a drone using a RPi B + and Navio+…all of this is very new but exciting !
I have downloaded the RT kernel for RPi2 on my Mac but I can’t seem to extract the image-tried everything, even “xz -d .img.xz” or unxz .img.xz, it keeps saying “No such file or directory”.
Any suggestion … ?
Hello and welcome, Maysun!
Could you please show us the commands you’d typed step by step?
It’s usually as easy as it gets:
dd bs=1M if=rasbpian.img of=/dev/<sd_device>
After these have finished, you can stick your SD card into Raspberry Pi and see it boot.
Just a quick note.
If you’d used the link in out docs, you would’ve downloaded a complete distribution image rather than a Linux kernel. These are separate notions.
Just in case, we have a detailed explanation on writing the image to SD card here in the docs.
