Date: Wed, 21 Mar 2001 19:29:40 +0800 MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Sender: owner-linuxppc-embedded@lists.linuxppc.org List-Id: Hello,all: Now I can boot linux on my 8260-based custom board. But I have a strange problem: ############################# ..................... VFS: Mounted root (nfs filesystem). Freeing unused kernel memory: 48k init Sash shell (version 1.0) sash# hel^@ ############################### After shell appears, I cannot run any built-in commands such as "ls" , "cp" etc... As you can see above, when I type 2 or 3 characters(for example, "hel"), then it appends "^@" automatically at once(So you see "hel^@" above). Then it stops there. It has no any response when I try to type any more characters. But I can ping it from my host computer. This means the target board is not crashed... Of course I am sure the root NFS is OK. I have tried cross-compile sash statically or dynamically, but both have the same result as above: ########################################### powerpc-linux-gcc -O2 -c -o sash.o sash.c powerpc-linux-gcc -O2 -c -o cmds.o cmds.c ..................... then: powerpc-linux-ld -O2 -static -s -o sash sash.o cmds.o ...... or powerpc-linux-ld -O2 -Wl,--rpath,/lib -o sash sash.o cmds.o ... ################################################ Any ideas? Thank you very much. machael ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
