Cannot Access Memory At Address 0x1
ret what i'm tring to examine is $0x208c. When I type x/xw 0x208c it gives me back error which says Cannot access memory at address 0x208c. When i type Info registers and look at eax it says the value which i provided. So basically this program compares two values and depending on that prints something out.The problem is that this is homework from university and I have not got code. Hope you can help. Thank you. c gdb share|improve this question asked May 9 '15 at 11:28 Ojs 152313 1 [finger in the air] you are passing an illegal parameter? You are sitting there, in front of the debugger. What could we work out that you cannot, especially with no source code? It's a very strange assignment that asks you to fix stuff without source... –Martin James May 9 '15 at 12:30 i finally figured out to use print statement instead of x/xw can you please explain why print worked and x didn't? –Ojs May 9 '15 at 12:32 $0x208c is an absolute value, not a memory address! –Sergio Formiggini May 9 '15 at 12:57 add a comment| 2 Answers 2 active oldest votes up vote 10 down vote accepted When I type x/xw 0x208c it gives me back error which says Cannot access memory at address 0x208c The disassembly for your program sa

Examples Overview This tutorial provides a concise explanation of frequently encountered bugs and how to use gdb to cannot access memory at address 0x4 debug serial programs at SHARCNET. It is not comprehensive and only aims to give users enough knowledge to get started on their own. To debug parallel programs users should consult the http://stackoverflow.com/questions/30139356/gdb-cant-access-memory-address-error SHARCNET Parallel Debugging with DDT tutorial. Note that it can also be used to debug serial programs, should one desire a graphical interface. Identifying bugs and errors Typically one realizes they've encountered a problem with their program when it fails to complete (crashes) or when it doesn't produce the expected output (either corrupted/incorrect output or a failure to progress (hangs)). One https://www.sharcnet.ca/help/index.php/Common_Bugs_and_Debugging_with_gdb can determine that a job exited in an erroneous state by inspecting the job exit code in the web portal (see the jobs table at the bottom of your your activity page) or by looking at the job output file (every job submission with sqsub should use the -o option to specify one). The output from the job can also indicate a problem with the state of the program or a lack of progress. For more information on diagnosing the behavior of jobs see Monitoring Jobs. When a job fails it's output may contain a runtime error message or a signal from the operating system that helps identify the problem. If no error message is generated or if the message is insufficient one can use a debugger to manipulate and inspect the code as it is running to identify the nature and scope of the problem. Common bugs and errors Some frequently encountered OS signals resulting from a program encountering an erroneous state include: Signal NameOS signal #OS signal nameDescription Floating point exception8SIGFPEThe program attempted an arithmetic operation with values that

I'm using a Murata development board with a Dialog Semiconductor Bluetooth Low Energy radio as the processor. The radio uses an ARM Cortex M0 core. I tried following Dialog's instructions for setting up a project in Keil and adapted them for Eclipse. Here's what I've set: Debug Configuration: JLink Device: ARMCM0 CPU freq: 16000000 SWO freq: 2000000 Uncheck pre-run reset and halt Preferences -> String Substitution: jlink_path /usr/local/gcc-arm-none-eabi-4_8-2014q3 I've also set the IRAM and IROM settings for the device in the project -> C/C++ Build -> Settings -> Devices tab (for the ARMCM0 device). The edit button didn't seem to work so I changed the .cproject file directly:
