Thanks a lot for your input. This is o/p for my busybox.I am booting with INITRAMFS. and kernel version is 2.6.30.9. I also try latest codesourcery mips toolchain and result is same. I could not get any hint to debug this issue. #mips-linux-gnu-readelf -l busybox Elf file type is EXEC (Executable file) Entry point 0x400180 There are 5 program headers, starting at offset 52 Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz Flg Align REGINFO 0x0000f4 0x004000f4 0x004000f4 0x00018 0x00018 R 0x4 LOAD 0x000000 0x00400000 0x00400000 0x1a8c6f 0x1a8c6f R E 0x10000 LOAD 0x1a9000 0x005b9000 0x005b9000 0x03170 0x084ac RW 0x10000 NOTE 0x0000d4 0x004000d4 0x004000d4 0x00020 0x00020 R 0x4 TLS 0x1ab464 0x005bb464 0x005bb464 0x00018 0x0004c R 0x4 Section to Segment mapping: Segment Sections... 00 .reginfo 01 .note.ABI-tag .reginfo .rel.dyn .init .text __libc_freeres_fn __libc_thread_freeres_fn .fini .rodata __libc_subfreeres __libc_atexit __libc_thread_subfreeres .gcc_except_table 02 .eh_frame .tdata .ctors .dtors .jcr .data.rel.ro .data .got .sdata .sbss .bss __libc_freeres_ptrs 03 .note.ABI-tag 04 .tdata .tbss On Fri, Feb 4, 2011 at 11:09 PM, David Daney <ddaney@xxxxxxxxxxxxxxxxxx> wrote: > On 02/04/2011 08:26 AM, Ian Lance Taylor wrote: >> >> keshav yadav<keshav.yadav2005@xxxxxxxxx> writes: >> >>> I observe one different behavior when we have page size set to 4KB or >>> 16KB in kernel busybox receive argc[0] argument correct, but >>> when page size set to 64KB I am getting argv[0] as empty.
