Be aware that there is some timing problems on the SDRAM interface on the 826x CPUs (Look at motorolas site) This sound very much like the problems I had before I fixed the hardware on an inhouse board.

(use uboot as bootloader.) I use some debug tools and find when paging_init( ) function finished (start_kernel --setup_arch--paging_init), some codes were destroyed such as sort_exception_table( ) (the next line in setup_arch( ), so the kernel hang) , some codes were protected well such as memset( ). (using LED in parallel port(adding some codes in kernel), I got the same results,the kernel hang after paging_init( )) what's the reason? Any advise will be appreciated. best regards. liu ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
