"Base address not aligned on size of device" Error
Nios II Flash Programmer User Guide © March 2014 Altera Corporation
Probable Cause
The flash device base address being passed to the Flash Programmer is not a multiple
of the flash device's size.
Suggested Actions
■ Ensure that the flash device is mapped to a base address in Qsys that is a multiple
of the flash size listed in its CFI table.
■ If in command line mode, ensure that the --base parameter you are passing to
nios2-flash-programmer
is the correct base address of the flash device in your
Qsys system.
