Hi, I created crosstool for arm-9tdmi-linux-gnu. I compiled a simple program using arm-9tdmi-linux-gnu-gcc. (My target board has already Kernel-2.6.10 and a compiler for older versions of gcc & glibc) I mount: mount -o nolock,rsize=1500,wsize=1500 -t nfs 161.85.96.148:/home/pramod/crosstool /mnt/test Ive simply used ./a.out. But its giving " sh:./a.out not found " even when there is compiled a.out in /mnt/test. when i use: crosstool/gcc-3.4.3-glibc-2.3.4/arm-9tdmi-linux-gnu/arm-9tdmi-linux-gnu/lib/ld-linux.so.2 ./a.out its giving " illegal instruction " I can find crosstool/gcc-3.4.3-glibc-2.3.4/arm-9tdmi-linux-gnu/arm-9tdmi-linux-gnu/lib/ld-linux.so.2 Do u doubt crosstol build itself gone wrong? But i tested arm-9tdmi-linux-gnu-objdump; works properly. What all should I take care while compiling a program and running a program in the TARGET? Plz reply with all the possibilities where the thing gone wrong. Thanx n regards, -- ---------------------------------------------------------------- PRAMOD P.
