I am trying to debug bootloader with gdb in QEMU. I run QEMU command like
this

./qemu-system-mips64 -s -S -m 1024 -M  octeon  -bios
u-boot-octeon_ebh5610.bin  -kernel vmlinux.64 -append 'coremask=001 mem=0
root=/dev/sda2'

and then connect gdb using

mips64-octeon-linux-gnu-gdb u-boot-octeon_ebh5610
target remote localhost:1234

when i try to step into bootloader code, it continues execution without
breaking. This totally skip the bootloader code which i want to examine
step by step as it execute.
Can anyone suggest, what do i need to do to resolve this issue.
Thank You
