The purpose of the tool is to access/configure a PCI-express cards that has some firmware running on it. I made some slight change to code,nothing significant and suddenly got a "Bus error". I know that is is caused by unaligned memory access, but in the above context is it more likely to be in the firmware memory, i.e a firmware read across the

PCI-express bus. I certainly don't believe that my small software change could have caused the "Bus error". Another surprising fact is that a different version of software is working well with this firmware. Can anyone throw some light on the issue. linux debugging bus share|improve this question edited May 3 '11 at 13:44 skaffman 277k63618656 asked May 3 '11 at 13:40 liv2hak 3,8691659109 closed as off-topic by Ciro Santilli 烏坎事件2016六四事件 法轮功, Yu Hao, Chris Loonam, John Pirie, Rob Aug 7 '15 at 16:35 This question appears to be off-topic.

challenged and removed. (July 2015) (Learn how and when to remove this template message) In computing, a bus error is a fault bus error centos raised by hardware, notifying an operating system (OS) that a ubuntu bus error process is trying to access memory that the CPU cannot physically address: an invalid address for the
Mmap Bus Error
address bus, hence the name. In modern use on most architectures these are much rarer than segmentation faults, which occur primarily due to memory access violations: http://stackoverflow.com/questions/5870353/bus-error-system-error problems in the logical address or permissions. On POSIX-compliant platforms, bus errors usually result in the SIGBUS signal being sent to the process that caused the error. SIGBUS can also be caused by any general device fault that the computer detects, though a bus error rarely means that the computer hardware is physically broken—it https://en.wikipedia.org/wiki/Bus_error is normally caused by a bug in a program's source code.[citation needed] Bus errors may also be raised for certain other paging errors; see below. Contents 1 Causes 1.1 Non-existent address 1.2 Unaligned access 1.3 Paging errors 2 Example 3 References Causes[edit] There are at least three main causes of bus errors: Non-existent address[edit] Software instructs the CPU to read or write a specific physical memory address. Accordingly, the CPU sets this physical address on its address bus and requests all other hardware connected to the CPU to respond with the results, if they answer for this specific address. If no other hardware responds, the CPU raises an exception, stating that the requested physical address is unrecognized by the whole computer system. Note that this only covers physical memory addresses. Trying to access an undefined virtual memory address is generally considered to be a segmentation fault rather than a bus error, though if the MMU is separate, the processor can't

I checked with all other bus error threads but none helped. My skype is not starting. When I run it in terminal I get "Bus error". how to fix I uninstalled and then installed but it did not help. I cleared all cache using "sudo apt-get clean all" and BleachBit but none of them helped. This problem is happening with some other applications also. some are working and some are not. The ones that are not working, are giving bus error. They all were working around week back. I only did automatic update and nothing else around that time. What could be the problem? Can someone please help? I am using Linux Mint 13.

Earlier it was working alright. I don't remember making any custom installation. Automatic software update crashed though and was not updating. It was giving 'error reading database' but got resolved automatically after few days. I guess I am having this problem since then. Any help or guidance is lot appreaciated.

Somewhere I read that it might be because of broken filesystem. So, I am trying fsck.
