Linux/AM5728: After unlimited ulimit, core file not dumped.

Part Number:AM5728

Tool/software: Linux

Hi ,

    I noticed the ulimit conf is 0 by default when I want a core in gdb mode.

Then I shell" >> ulimit -c unlimited "to open it.

Then gdb a elf.

After I shell" >> kill pid " to kill that process, it shows "Abort (core dumped)".

But, I can't find in the same folder.

My question is , how can I get a dumpcore on am5728?
