ID:210094 The HEX file <name1> located in the Main Block is not aligned on a 16-bit boundary

CAUSE: The Quartus Prime software places the last byte of data in the last location in flash memory. The Hexadecimal (Intel-Format) Files (.hex) file has a odd number of bytes or has holes that are shifting the data off a 16-bit boundary.

ACTION: If your application can tolerate misaligned data, then no change is needed, otherwise rebuild your hex image and eliminate any holes or misalignments in the image.
