Data corruption in Qsys (Beta) might occur when an Avalon Memory-Mapped (MM) master writes to an Avalon-MM slave

Description

If an Avalon Memory-Mapped (MM) master writes to an Avalon-MM slave that does not have a byte enable input signal and has a wider data width than the master, data corruption might occur on the slave words.

Resolution

Add a byte enable signal to any slave that has a wider data width than its master.
