Bad emulation

subratasaharia · #1 (**permalink**) 10-15-2009

I am using mpc8xx processor with linux-2.4.20 kernel. These prints are getting flooded to my console almost consistenly.

Code:

I am concerned over the "Bad Emulation" print. Does it appear if we use floatng points in our application softwares as mpc8xx is not equipped to handle floating points?
Is there a fix for this ? Will compiling the application s/w with some appropriate flags solve this issue??

Thanks in advance.!

I would have been more concerned by the I/O error you have...
