Hi,
I had designed custom board using icm20948. i tried to get raw values from sensor and succeed then i had ported nucleo code for nrf53 zephyr. when i tried to run below code
inv_icm20948_serif_i2c_init(usr_read, usr_write);
/*
* Create icm20948 Device
* Pass to the driver:
* - reference to serial interface object,
* - reference to listener that will catch sensor events,
* - a static buffer for the driver to use as a temporary buffer
* - various driver option
*/
inv_device_icm20948_init(&device_icm20948, &icm20948_serif,
&sensor_listener, dmp3_image, sizeof(dmp3_image));
/*
* Simply get generic device handle from icm20948 Device
*/
device = inv_device_icm20948_get_base(&device_icm20948);
/*
* Just get the whoami
*/
rc = inv_device_whoami(device, &whoami);
printk("ICM WHOAMI=%02x", whoami);
check_rc(rc);
/*
* Check if WHOAMI value corresponds to any value from EXPECTED_WHOAMI array
*/
for(i = 0; i < sizeof(EXPECTED_WHOAMI)/sizeof(EXPECTED_WHOAMI[0]); ++i) {
if(whoami == EXPECTED_WHOAMI[i])
break;
}
if(i == sizeof(EXPECTED_WHOAMI)/sizeof(EXPECTED_WHOAMI[0])) {
printk("Bad WHOAMI value. Got 0x%02x. Expected @EXPECTED_WHOAMI@.", whoami);
check_rc(-1);
}
/*
* Configure and initialize the icm20948 device
*/
printk( "Setting-up ICM device");
rc = inv_device_setup(device);
check_rc(rc);
/*
* Now that Icm20948 device was inialized, we can proceed with DMP image loading
* This step is mandatory as DMP image are not store in non volatile memory
*/
printk("Load DMP3 image");
rc = inv_device_load(device, NULL, dmp3_image, sizeof(dmp3_image), true /* verify */, NULL);
check_rc(rc);
my device run for first time with correct value of inv_device_whoami (). then i2c stop working.
kindly support get run on my custom board. why this happened. my second board also stop working just as first one.
