The latest reference board I got also has an 8MB SIMM flash module shipped in the box. > > I'm posting this as reference in case the 8 MB should turn out to be > correct. -- wd Although 8MB seems to be the common size used. It can be very easy changed as a pluggable module. It might be better to make the code working for any reasonable flash sizes. - Leo _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
