Remote Gdb Cannot Find Bounds Of Current Function


Many years. We recommend upgrading to the latest Safari, Google Chrome, or Firefox. But the instruction pointer is on the stack, it's not covered by any debug info. Spritetm commented Nov 30, 2015 Also, I see you use xt-gdb, which is probably the Tensilica-built GDB. check my blog

I'm pulling my hair out on this one... Can I use that to take out what he owes me? Also, are you sure you have the softdevice on the chip? But you probably have another problem in addition to that. –Steve Jessop Jan 5 '12 at 11:30 How could i add debug info for the nop instruction, which is http://stackoverflow.com/questions/8741493/why-i-do-get-cannot-find-bound-of-current-function-when-i-overwrite-the-ret-ad

Cannot Find Bounds Of Current Function In Gdb

If yes, can I set a breakpoint somewhere inside of it after the first execution? It overwrites the current stack frame of your function with irrelevant data, and destroys the return address in the process, which is normally stored there among other things. I thought you were asking why you need to compile with no-stack-protector, and answered. –ugoren Jan 5 '12 at 17:39 There is no other way as far as i I can load and stepi instructions just fine, but when I try to step a source line, gdb reports an error, "Cannot find bounds of current function".

When does TNG take place in relation to DS9? Using "until" it breaks into library code somewhere without any reference how to get back to my code. Almost as if it's using two different numbers for the PC (one in the correct endian sense, the other not).

The same program steps fine on the simulator, and I've verified that there are no differences between the sp, lr, pc, or other register values between the two environments. And the code you jump to can vary a lot. Accordingly, I've tried to do that but always getting the following error ("Cannot find bounds of current function") on startup. $ arm-none-eabi-gdb.exe tmp_gcc_s110_xxaa.out GNU gdb (GNU Tools for ARM Embedded Processors) http://stackoverflow.com/questions/22838955/cannot-find-bounds-of-current-function Logged Fedora package maintainer for Code::BlocksJens' Debian - nightlies (and release)Fedora [23 - 25]- and CentOS/RedHat 7 - nightlies ollydbg Developer Lives here!

If a function, that was located in FLASH, is executed then is its code moved to RAM after its first execution? Also please confirm that you are not optimizing the code when you compile it.

This makes it much harder for the attacker to guess what will be the value he wants to store (through a buffer overflow) over the "return address" slot. Hence it is no wonder that gdb cannot find where the "function" he jumped in is supposed to begin or end. up vote 3 down vote favorite 1 I want to exploit a stack based buffer overflow for education purposes.There is a typical function called with a parameter from main which is http://rss4medics.com/cannot-find/qemu-cannot-find-bounds-of-current-function.php Adv Reply April 26th, 2011 #3 BkkBonanza View Profile View Forum Posts Private Message Staff Emeritus Join Date Apr 2008 Location Far, far away Beans 2,148 DistroUbuntu 11.04 Natty Narwhal

And I have some difficulties debugging step by step. I run the loop over and over, entering keystrokes, with a breakpoint in the middle and it never breaks. It would be great if someone can tell me what am I doing wrong.
