Re: [Ltib] gcc + uclibc for e300 core

[Steve Papacharalambous]

Hi Ryan,

No, I'm afraid not.  :-(

We haven't received any other reports of Illegal Instruction crashes
with this toolchain.

The only thing that I can suggest is to track down the instruction is
causing the run time error and then the problem can be fixed,

Best regards,

Steve
