I've a PPC823 board working with a recent linux kernel based on monta vista. When I try complex operation like compiling a kernel on this board, the kernel crash after a while. An illegal instruction is generated, linux see an opcode: *NIP=0, the illegal instruction occur in a glibc-2.1.3 page. The glibc page is not see properly... This problem seems to occur only on complex operation, and make this system not reliable.
I also have a PPC750 board working with the same kernel with proper configuration, the only differences in code is the MMU part. Linux work properly and reliably on this board with the PPC860 software. if you have see a similar behaviour on you boards, or with differents processor. I know that the PPC823 is not 100% compatible with the PPC860, there is some differences on TLB available etc... And linux seems to be hard coded for 32 TLB... If you know how the MMU is handle on linux 8xx, and if you see a similar behavior let me know... Patrick LERDA ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
