I am running Kepler on my Mac OSX latest OS version. I have installed the CDT package as well as many ARM toolchains but currently using the gcc-arm-non-eabi- one. The problem is that while the code compiles a debug session, when I try to debug the following message is produced: "Error in final launch sequence Failed to execute MI command: tbreak main Error message from debugger back end: Cannot access memory at address 0x800030a
Error In Final Launch Sequence Failed To Execute Mi Command Maintenance Set Python Print-stack Off
Cannot access memory at address 0x800030a" I am using the Segger J-link applications as well as a Segger JTAG debugger, the target is the NXP LPC 1768. I suspect the problem here is in the debugger end of my setup but when running the jlink utilities by themselves, they seem to work properly. Can someone help me decode what the MI command is? I suspect that whatever it is it is not compatible with my setup. I apologize in advance for the newbie question. regards, Jim Report message to a moderator Re: ARM Debugging in Eclipse OSX [message #1402078 is a reply to message #1402071] Wed, 16 July 2014 13:33 Marc KhouzamMessages: 357Registered: July 2009 Senior Member When CDT launches, it tries to set a breakpoint at main, so it will interrupt execution when your program starts. However, your target is already running so the breakpoint cannot be set and the whole things fails. You could simply tell your launch not to set that breakpoint and let it connect to your target. Go to: Run->Debug Configurations... and find your launch configuration. Then select the Startup subtab, scroll down and uncheck "Set breakpoint at" in the "Runtime options" subsection.

(gdb) p/x *($esi) Cannot access memory at address 0xe6d3a030 I mention that the address pointed by %esi (0xe6d3a030) should point to some http://stackoverflow.com/questions/14896534/why-do-i-get-in-gdb-cannot-access-memory-at-address-0x-while-inspecting-a-c valid allocated data. ( when I run this program myself and break on the same instruction this print has some meaningful information ) What are the possible causes for this? Am I missing some info from the core dump? If yes what information am I missing? Shouldn't the core dump contain a snapshot of all the allocated memory? edit: when I use in gdb "maintenance info sections" command while the coredump is loaded I get the info presented bellow. I can see that the address 0xe6d3a030 is in the range 0xe6d00000->0xe6dfb000 at 0x0f5aa000: load93 ALLOC LOAD HAS_CONTENTS Doesn't this mean it was loaded?

Pathscale Compilers 4.2 Intel Compilers 5 Using gdb 5.1 first bug: an FPE 5.2 second bug: a segmentation fault 5.3 using core files 5.4 debugging interactively 5.5 Hungup Processors 5.6 documentation 6 Other useful debuggers 7 Examples Overview This tutorial provides a concise explanation of frequently encountered bugs and how to use gdb to 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 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 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 do not make sense (eg. divide by zero) Segmentation fault11SIGSEGVThe program accessed memory incorrectly (eg. access
