I want to add the LSM6DS3 sensor driver in my AOSP source code. I am using SC600T device.
I have already add
lsm6ds3to the location/SC600T/SC60_SC600_Android9.0.0_kernel4.9_r029/kernel/msm-4.9/drivers/iio/imu/st_lsm6ds3, withMakefileandKconfigfiles.Added below line to
/../../iio/imu/Kconfigfile:source "drivers/iio/imu/st_lsm6ds3/Kconfig"Added below line to
/../../iio/imu/Makefile.
obj-y += st_lsm6ds3/
- Content of
/SC600T/../../iio/imu/st_lsm6ds3/Makefile:
# SPDX-License-Identifier: GPL-2.0-only
st_lsm6dsx-y := st_lsm6dsx_core.o st_lsm6dsx_buffer.o \
st_lsm6dsx_shub.o
obj-$(CONFIG_IIO_ST_LSM6DSX) += st_lsm6dsx.o
obj-$(CONFIG_IIO_ST_LSM6DSX_I2C) += st_lsm6dsx_i2c.o
obj-$(CONFIG_IIO_ST_LSM6DSX_SPI) += st_lsm6dsx_spi.o
obj-$(CONFIG_IIO_ST_LSM6DSX_I3C) += st_lsm6dsx_i3c.o
- I have also added
lsm6ds3node in the device tree file:
&i2c_2 {
status = "ok";
#address-cells = <0x1>;
#size-cells = <0x0>;
lsm6ds3@6b {
compatible = "st,lsm6ds3";
reg = <0x6b>;
interrupt-parent = <&tlmm>;
interrupt-gpios = <&tlmm 45 0x2008>;
interrupts = <45 0x02>;
};
I have connected LSM6DS3 accelerometer Sensor on SENSOR_I2C_SCL (Pin number 131) and SENSOR_I2C_SDA (Pin number 132).
After that I have compiled the source code and flash boot and dtbo on target device(SC600T) successfully.
When I am trying to check sensor data using adb shell >> /sys/bus/devices/i2C/devices node is available and
lsm6ds3 address node which is 6b is also available.
But lsm6ds3 sensor is not probed.
enter image description here
Then after I will add below lines in msm8953_defconfig file.
- Added below lines in msm8953_defconfig fie:
CONFIG_IIO_ST_LSM6DSX=y
CONFIG_IIO_ST_LSM6DSX_I2C=y
CONFIG_IIO_ST_LSM6DSX_SPI=y
CONFIG_IIO_ST_LSM6DSX_I3C=y
after adding this file when i compiling the source code getting below errors:

Adding any custom sensor in the AOSP, are this all steps mandatory or not? Why lsm6ds3 sensor is not probed? Do I need to check anything from the hardware side?
