nuttx/include/errno.h define ENODEV to 19:
#define ENODEV 19
and nuttx/drivers/sensors/adxl372.c return ENODEV if id mismatch:
static int adxl372_dvr_open(FAR void *instance_handle, int32_t arg)
{
/* Read the ID registers */
pnpid = adxl372_read_id(priv);
priv->readonly = false;
sninfo("ADXL372_ID = 0x%08x\n", pnpid);
if ((pnpid & 0xffffff00) != (ADXL372_DEVID_AD_VALUE << 24 |
ADXL372_DEVID_MST_VALUE << 16 |
ADXL372_PARTID_VALUE << 8))
{
snwarn("ERROR: Invalid ADXL372_ID = 0x%08x\n", pnpid);
priv->readonly = true;
set_errno(ENODEV);
}
You have to check what's the value in pnpid.
