I just got a Sansa Clip+ and installed the newest version of Rockbox on it. My 32gb card works with both OF and Rockbox, but my "Sandisk Ultra" 64gb card appears only to be detected by the OF... at least that's how it appears.
When I launch rockbox with the (fully loaded) 64gb card inserted, it hangs. Even if I take the card out, the player is unresponsive until I restart it. Will it eventually update itself, or is it incapable of reading that card/that many files?
