[yocto] tiny-linux distribution with raspberrypi error

[Khem Raj]

I think you can generate a SD card image which can be dd’ed into a sd card
​poky tiny by default generates an initramfs image only. ​
​
​you can add

IMAGE_FSTYPES_append = " rpi-sdimg​"

​in local.conf and see if you get a rpi-sdimag​
