Wouldn't it be a little more helpful if you post more details like what you are doing and a screenshot of your screen would be great?

Hi. I'm stepping in a so lib in runtime  with ida pro in arm debug mode. I found interesting strings in data section and I would like to discover what code instructions read these strings, but I cannot set hardware breakpoints there. How can I stop ida when these ascii strings are read? Thanks

I saw somethings, but I'm looking for a way to BP in memory area in android arm debugging, not in windows. I want to set a read/write breakpoint in specific Memory address.... Thanks

Hi to all.

In arm debugging with idapro, i'm looking for a crc checksum routine (and I know how much sum is) inside a so file.

I'm still looking for a way in ida to set breakpoint read/write in code address. It's possibile?

And it's also possible to set a bp in order to check if a register (like r1,r2...) has a specific value without knowing in what address it happens?

Thanks

first in that string section press ALT+X and you will see which subroutines which has refer. to it and put BP on all the subroutines there in text section is .so file and classes.dex has code section

Thanks Jasi. i'll try this technique even if I would like to discover a CRC routine that counts code bytes not text... However i didn't know alt+x command for references. 👍😫
