Hi, I face an issue using Valgrind wherein it complains on out of memory can anyone advise any pointers to the issue. Below are the logs for the issue. free_mem_available.txt (657 Bytes) valgrind_fail_to_run.txt (5.4 KB)

I don’t see problem with WP76 R13 with attached binary: valgrind.rar (3.3 MB) mkdir /tmp/valgrind mkdir /tmp/tmp_lib;mkdir /tmp/tmp_lib_wr; cp -rf /lib /tmp/tmp_lib mount -t overlay overlay /lib -o lowerdir=/lib,upperdir=/tmp/tmp_lib,workdir=/tmp/tmp_lib_wr; Use WINSCP to transfer all the binary …

@jyijyi , The issue is seen in R16 let me check on R16 and come back to you. Thanks & Regards, Pankaj Sant

@jyijyi For the valgrind did you collect it from the /tmp/work directory of the linux source? for R16 I believe I will have to build it with R16 source right?

please see here: [image] How to use Valgrind on WP76 to investigate memory leaks Legato Linux distribution (Yocto project) You can try the procedure below on WP76 R13.3: download the yocto source code open ./meta-swi/meta-swi-mdm9x28/recipes-core/images/mdm9x28-image.in…

@jyijyi , Following the process we are seeing segfault and oom killer. attached are the dmesg logs. dmesg_oom.dat (114.7 KB)

@jyijyi , your binary is with R13 the firmware in the device is R16 so tested with R16. Can you share a binary for R16 and will test it on the device.

It can still be used in r16 as it is compiled by ARM version. Please see below: root@swi-mdm9x28-wp:/tmp/valgrind# ./valgrind --leak-check=full --show-leak-kind s=all --verbose ./vgdb ==2684== Memcheck, a memory error detector ==2684== Copyright (C) 2002-2017, and GNU GPL'd, by Julian Seward et a…
