    Which 32GB SanDisk card did you use that worked?

    I've tried Sandisk Ultra UHS-1 32GB MicroSD (with adapter) and the linux kernel hung during boot - before even trying to mount the rootfs.

    My Sandisk Ultra UHS-1 16GB MicroSD card fails the same way.

    My Sandisk Ultra UHS-1 8GB MicroSD card works fine.

    Why does the 8GB work?  Did I just get lucky?
    Why does 32GB fail (same brand, type, etc) ?

    I tried a 16GB Samsung EVO UHS-1 and that worked.  I will try a Samsung 32GB EVO soon.

    However, I don't feel confident with all this.  Is it just pot luck?  Surely there must be some spec that says these types of cards should or shouldn't work.

    Any help greatly appreciated.
