sp-rich-core
Description
sp-rich-core is a package that installs an init script that pipes core dumps through a script. This script collects lots of information from the system and then saves that and the core dump data compressed into a file (by default onto an MMC card). The collected information includes process SMAPS data, most of /proc data, last lines from syslog, df and ifconfig output etc.
Compressing the core dumps (with lzo) actually speeds up saving them.
Use rich-core-extract (from sp-rich-core-postproc package) to extract the information from a rich core dump.
Packages
source: sp-rich-core
binary: sp-rich-core, sp-rich-core-postproc
Usage Examples
In order to get core dumps, one of these directories needs to exist: /media/mmc1/core-dumps or /media/mmc2/core-dumps.
Create a small program that's sure to crash:
- - - snip crasher.c - - -
int main()
{
char *p = 0;
memcpy(p, 0x00, sizeof(p));
}
- - - snap crasher.c - - -
# gcc -g -o crasher crasher.c
After copying the crasher program to your device and having installed the sp-rich-core package, you can now run the program.

The directory will contain lots of potentially useful information in addition to the core dump file.
