In Linux SDK, where can I check or change the stack size and heap size of the ARM program and DSP program ?
For the stack size of a DSP program, perhaps look a the linker command file for the DSP program.
On the arm to get the current Stack size,
root@am180x-evm:~# ulimit -atime(seconds) unlimitedfile(blocks) unlimiteddata(kb) unlimitedstack(kb) 8192coredump(blocks) 0memory(kb) unlimitedlocked memory(kb) 64process 989nofiles 1024vmemory(kb) unlimitedlocks unlimited
<< setting the stack size on the ARM to 32K >>
root@am180x-evm:~# ulimit -s 32768
root@am180x-evm:~# ulimit -atime(seconds) unlimitedfile(blocks) unlimiteddata(kb) unlimitedstack(kb) 32768coredump(blocks) 0memory(kb) unlimitedlocked memory(kb) 64process 989nofiles 1024vmemory(kb) unlimitedlocks unlimited
In reply to Schuyler Patton:
Hi Schuyler,
Your method is not a permanent change because I need to change it every time when I run the program.
How can I change stack size permanently so that when I compile and run the ARM program, the change is permanent ?
Similarly, how to permanently change the heap size size of the ARM program ?
Thanks,
Mr Tan
In reply to std:
There are no limits stored in the program file.
Heap and stack sizes are user resource limits, which can be set for all programs run from a shell with the ulimit command, or from the program itself with the setrlimit system call (if the user has sufficient privileges; see the man page).
