Hello,
I'm working on an application running on the nRF9160. The application is build on the Fanstel BLG840X and the code is shared between both the 52840 and 9160 on the BLG840X, but the errors are coming from the 9160. I am getting stack overflow hardfault errors when using snprintk and mallc_k. The error I get is below:
I assumed this meant that variables I had created were exceeding the allocated stack memory, so I looked into my config file below:
CONFIG_AWS_IOT=y CONFIG_AWS_IOT_APP_SUBSCRIPTION_LIST_COUNT=2 CONFIG_AWS_IOT_BROKER_HOST_NAME="..." CONFIG_AWS_IOT_CLIENT_ID_STATIC="..." CONFIG_AWS_IOT_LAST_WILL=y CONFIG_AWS_IOT_SEC_TAG=702 CONFIG_AWS_IOT_TOPIC_GET_ACCEPTED_SUBSCRIBE=y CONFIG_AWS_IOT_TOPIC_UPDATE_DELTA_SUBSCRIBE=y CONFIG_HEAP_MEM_POOL_SIZE=8192 CONFIG_LTE_AUTO_INIT_AND_CONNECT=n CONFIG_LTE_LINK_CONTROL=y CONFIG_LTE_NETWORK_MODE_LTE_M=y CONFIG_MAIN_STACK_SIZE=4096 CONFIG_MQTT_KEEPALIVE=180 CONFIG_NCS_SAMPLES_DEFAULTS=y CONFIG_NETWORKING=y CONFIG_NET_NATIVE=n CONFIG_NEWLIB_LIBC=y CONFIG_NEWLIB_LIBC_FLOAT_PRINTF=y CONFIG_NRF_MODEM_LIB=y CONFIG_REBOOT=y CONFIG_RTT_CONSOLE=y CONFIG_SERIAL=y CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=2048 CONFIG_UART_0_ASYNC=y CONFIG_UART_ASYNC_API=y CONFIG_UART_CONSOLE=n #was n CONFIG_USE_SEGGER_RTT=y CONFIG_FLASH=y CONFIG_FLASH_PAGE_LAYOUT=y CONFIG_NVS=y CONFIG_LOG=y CONFIG_NVS_LOG_LEVEL_DBG=y CONFIG_REBOOT=y CONFIG_MPU_ALLOW_FLASH_WRITE=y CONFIG_LOG_PRINTK=y CONFIG_LOG_PROCESS_THREAD_STACK_SIZE=2048 CONFIG_LOG_BUFFER_SIZE=32768 CONFIG_LOG_STRDUP_BUF_COUNT=256 #date time library CONFIG_DATE_TIME=y
I tried doubling the values of:
CONFIG_HEAP_MEM_POOL_SIZE=8192
CONFIG_MAIN_STACK_SIZE=4096
CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=2048
CONFIG_LOG_PROCESS_THREAD_STACK_SIZE=2048
CONFIG_LOG_BUFFER_SIZE=32768
but still got the error. I wasn't sure what else might be causing this or what else I could try to do to fix it, since it seems like the stack overflow isn't due to running out of memory, unless there are other config options I need to change that I am unaware of.
Please let me know if you have an idea of what's going on or how to remedy this.
Thanks!
