Did all B2s use the same processor?

Post by sakaki » 02 Nov 2014, 08:01

Hello -

I've been working on porting Gentoo onto our aged Bubba 2, and was considering making a release image of this at some point...

However, I'm not sure whether the same system-on-chip was used in the B2 over its production run. Our says (via cat /proc/cpuinfo) that it is a MPC8313ERDB (with an e300c3 powerpc CPU) - is that true for all B2s? I'd like to use -mcpu=e300c3 -mtune=e300c3 with gcc (and powerpc-e300c3-linux-gnu with crossdev), but not if that'll result in object files that are incompatible with some earlier or later models...

Any help appreciated! Thx

Hi,

If my memory serves me correct it is the same model CPU on all B2s i.e. MPC8313ERDB. We did however have two silicon revisions of this chip. (Killing of a lot of uggly ethernet bugs :| )

Neither should impact instruction or object formats.
