I am using nrf5340 and icm20948 for our development. i had initialized things as shown in code attached.
this work fine for me. but when i am uncommenting rc |= inv_icm20948_enable_sensor(&icm_device, idd_sensortype_conversion(INV_SENSOR_TYPE_MAGNETOMETER), 1); system is giving error * buffer overflow detected * .
i tried to increase HARDWARE_FIFO_SIZE to 4096 from 1024 but still issue is available. then i tried to increase stack size
#define CONFIG_MAIN_STACK_SIZE 1024
#define CONFIG_PRIVILEGED_STACK_SIZE 1024
to 2048 and 4096
with all combination.
but still issue is present kindly help me
