I guess someone modified misc.c? I don't know what they indicate, either. > Total Memoty = 16MB;unsing 64kb for hash table (at c00d0000). > Linux version 2.2.11....... > Boot arguments: > Calibrating delay loop...14.44 BogoMIPS > remove_mem_piece: bad overlap [c8000,f4000) with [c8000, d0000) [e0000, 1000000) Don't messages like this get your attention? Something is wrong with the memory map, board information structure, or where you loaded the software kernel and ram disk. > > Memory: 15408k available (552k kernel code, 396k data, 28k init) [c0000000,c1000 > 000] > DENTRY hash table entries: 262144 (order: 9, 2097152 bytes) > Buffer-cache hash table entries: 32768 (order: 5, 131072 bytes) > Page-cache hash table entries: 4096 (order: 2, 16384 bytes) > POSIX conformance testing by UNIFIX > Linux NET4.0 for Linux 2.2 > Based upon Sw<6>NET4: Unix domain sockets 1.0 for Linux NET4.0. > NET4: Linux TCP/IP 1.0 for NET4.0 > IP Protocols: ICMP, UDP, TCP > TCP: Hash tables configured (ehash 16384 bhash 16384) > Starting kswapd v 1.5 > CPM UART driver version 0.02 > ttyS00 at 0x0100 is a SCC //i use scc2 as ttyS0 Really? So, you modified arch/ppc/mbxboot/m8260_tty.c to use an SCC? You have to make lots of changes to use SCC as a console. I don't have any board that uses the SCC for a serial port (easily, without some hardware hacking), so I haven't tried this. > Warning: unable to open an initial console. > /*open("/dev/console",...);*/ Not surprised if this is an SCC. You have some work to contribute :-). -- Dan ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
