support for FPU on PowerPC 440EP

Post by Peter Wächtler » Fri Mar 23, 2007 5:07 pm

Hi all,

does anyone know if the procnto-booke and BSP for AMCC supports the FPU on
the AMCC PowerPC 440EP ? 440EP and 440EPx are the only variations that
supply a FPU.

If the FPU gets anabled in the startup, a message is displayed on the
console and the system is locked:

Crash(0,0) in config_cpu line 91

I suppose this message is from procnto-booke because there's no function
config_cpu defined in the startup code. Is that right?

regards
Peter

It appears to have been added after the 632 Core OS release.
