CTS Failed for Accelerometer Sensor

Babu — Fri, 19 May 2017 12:15:42 GMT

Hi,

I am trying to run CTS for Hardware, on imx6 based custom board. Accelerometer used as suggested by nxp "lsm9ds1_acc".

while running CTS, we are seeing 37 failures in hardware package as mentioned below.


-- testAccelerometer_50hz_flush	fail	junit.framework.AssertionFailedError: VerifySensorOperation \| sensor='STM 3-axis Accelerometer', samplingPeriod=20000us, maxReportLatency=10000000us \| Magnitude mean out of range: mean=48469.617 (expected 9.80665+/-1.5) at junit.framework.Assert.fail(Assert.java:50)

We tried to debug further in HAL layer of the sensors, HAL is implemented on top of the deprecated version

Platform:

Processor: IMX6dq

Android : android-6.0.1_r3

Ref: https://source.android.com/devices/sensors/versioning

Please suggest, If you have updated stack for above mentioned sensor.

Thank You

Babu A

Hello Babu A,

I’m just curious, where did you find the suggestion for the lsm9ds1_acc?

I looked for information regarding this but I’m afraid I couldn’t find much, especially on what it’s related to CTS.

I would recommend looking on the manufacturer’s documentation and forums and even on android developer forums as they may have more information on this part number.

Regards,

Hi gusarambula

Thanks for your reply.

Sorry for the inconvenience. Sensor in not suggested by NXP. But the HAL implemented code signature mentioned as developed by freescale.
