Heap memory issues

Rakshita

I am facing heap memory issues in my code. I am using dynamic memory allocation for saving microphone data into sd card. Along with this I am using wifi also.

CONFIG_HEAP_MEM_POOL_SIZE=153600 this configuration is already large.
I am attaching my code for reference.

    When I don't place the breakpoint in the faults.c, I get 

    [00:00:37.674,804] <err> os: ***** USAGE FAULT *****
    [00:00:37.674,804] <err> os: Illegal load of EXC_RETURN into PC
    [00:00:37.674,835] <err> os: r0/a1: 0x0cdb1640 r1/a2: 0x0cd4162e r2/a3: 0x0cca162c
    [00:00:37.674,835] <err> os: r3/a4: 0x0cc11630 r12/ip: 0x0cbc162a r14/lr: 0x0cc21630
    [00:00:37.674,865] <err> os: xpsr: 0x0ce01600
    [00:00:37.674,865] <err> os: Faulting instruction address (r15/pc): 0x0ccd1635

    [00:00:38.072,448] <err> os: Halting system

    So I already made a addr2line.sh file in which I am executing arm-none-eabi-addr2line -e build/zephyr/zephyr.elf pc address 

    So I run ./addr2line.sh 0x0ccd1635 but I get ??:0

    It is unclear why this fault happens based on the limited logs that is generated. We can improve the information of the fault logs if you add these below in your prj.conf, recompile, flash and run the new binary.

    CONFIG_REBOOT=y
# CONFIG_RESET_ON_FATAL_ERROR=y
CONFIG_FATAL_ERROR_LOG_LEVEL_DBG=y
CONFIG_BT_HCI_VS_FATAL_ERROR=y


CONFIG_EXTRA_EXCEPTION_INFO=y

CONFIG_THREAD_NAME=y
CONFIG_THREAD_ANALYZER=y
CONFIG_THREAD_STACK_INFO=y
CONFIG_THREAD_MONITOR=y
CONFIG_THREAD_ANALYZER_ISR_STACK_USAGE=y
CONFIG_THREAD_ANALYZER_AUTO_INTERVAL=5
# CONFIG_THREAD_ANALYZER_USE_PRINTK=n
CONFIG_THREAD_ANALYZER_AUTO=y
CONFIG_THREAD_ANALYZER_USE_LOG=y


CONFIG_INIT_STACKS=y
CONFIG_STACK_USAGE=y

#CONFIG_MPU_STACK_GUARD=y
#CONFIG_STACK_SENTINEL=y



CONFIG_IDLE_STACK_SIZE=4096
CONFIG_MAIN_STACK_SIZE=8196
CONFIG_ISR_STACK_SIZE=8196
CONFIG_MPSL_WORK_STACK_SIZE=8196
CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=8196

    With this, we hopefully get more context to see if there is a stack overflow in any thread and which thread executed a instruction that caused a fault.

    After enabling the above configurations you mentioned, I got the below logs
