[yocto] tiny-linux distribution with raspberrypi error

[Sherif Omran]

i tried the following
bitbake -c clean rpi-basic-image (to clean the build)

added the following to the local


IMAGE_FSTYPES_append = " rpi-sdimg" => when i copied the text from the
email, it gave class unavailable and then i found that there is a hidden
character before the end quotes from another language. By writing it, it
worked.

thank you
