Hey,
I just built the code from source and flashed it. Next I got a 16GB and 64GB sdcards, formatted them to FAT32 and added epub files. When I booted the device, I get the constant Core 1 panic'ed (LoadProhibited). Exception was unhandled. errors.

ELF file SHA256: 2b0bbcd6a1a0f501

Seems like it is an issue with one of the epub files I have added. When only adding one, it works.
