Some parts of the project use little-endian byte order while others use big-endian byte order.
However, the processor is intended to be little-endian.

Parts that need fixing:

  • neorv32_exe.bin executables are big-endian
  • bootloader uses big-endian memory layout
  • mstatush CSR states the CPU is big-endian (but it is not!)
  • external memory interface states it used big-endian access by defualt (but it it not!)
