Hi, I'm using BMA456 accelerometer with I2C interface, with the following initialization code: uint16_t bma456_device_init() { uint16_t rslt = BMA4_OK; /* Modify the parameters */ s_dev.dev_addr = BMA4_I2C_ADDR_PRIMARY << 1; s_dev.interface = BMA4_I2C_INTERFACE; s_dev.bus_read = bma456_access_read; s_dev.bus_write = bma456_access_write; s_dev.delay = OS_PL_Delay; s_dev.read_write_len = READ_WRITE_LEN_16; s_dev.resolution = RESOLUTION_12_BIT; s_dev.feature_len = BMA456_FEATURE_SIZE; /* a. Reading the chip id. */ rslt |= bma456_init(&s_dev); if(rslt != BMA4_OK) { //ASSERT } /* b. Performing initialization sequence. c. Checking the correct status of the initialization sequence. */ rslt |= bma456_write_config_file(&s_dev); if(rslt != BMA4_OK) { //ASSERT } /* Declare an accelerometer configuration structure */ struct bma4_accel_config accel_conf; /* Assign the desired settings */ accel_conf.odr = BMA4_OUTPUT_DATA_RATE_100HZ; accel_conf.range = BMA4_ACCEL_RANGE_16G; accel_conf.bandwidth = BMA4_ACCEL_NORMAL_AVG4; /* Set the configuration */ rslt |= bma4_set_accel_config(&accel_conf, &s_dev); if(rslt != BMA4_OK) { //ASSERT } /* Enable the accelerometer */ rslt |= bma4_set_accel_enable(1, &s_dev); return rslt; The code get into assert after "rslt |= bma456_write_config_file(&s_dev);". When I debug it I saw that the problem occure after reading the config_stream_status i.e the ASIC not initialized. When I'm running the code in Debug-Mode I don't see this problem. 1. Can you help me understand why the ASIC not initialized? 2. Do I have to run bma456_write_config_file? when I removing this line the code work without problems... Thanks Nitzan
