Please double check on /proc/interrupts for existing id asm330lhh,
something like:
cat /proc/interrupts | grep asm330
if it exists then try with timeout set to 0:
iio_readdev -T 0 -b 1 asm330lhh_accel -s 100
Be sure to use the correct driver (the lsm6dsx is mainline driver, the asm330lhh is the repo driver, that are using the same compatible string "st,asm330lhh")
An alternative to libiio is generic_buffer
from stmems_linux_iio_drivers.

Dear Mariotesi,
Thanks for your reply!!
I changed to use repo driver at here: https://github.com/STMicroelectronics/st-mems-android-linux-drivers-iio
Now I am able to find "asm330lhh" in /proc/interrupts.
However, there is still no interrupt received. I tried both generic_buffer and libiio.
- Device Tree:
&hsi2c_10 {
status = "okay";
asm330lhhx-imu@0x6a {
compatible = "st,asm330lhh";
reg = <0x6a>;
interrupt-parent = <&gpp5>;
interrupts = <5 IRQ_TYPE_LEVEL_HIGH>;
st,int-pin = <1>;
st,mlc-int-pin = <2>;
mount-matrix = "1", "0", "0",
"0", "1", "0",
"0", "0", "1";
};
};- Could you help check following logs again? Thank you very much!!

I presume it depends on irq configuration, please check interrupt pin is connected to your target board application processor, furthermore consider the interrupt configuration of device tree is related to your hardware platform, for instance on Raspberry pi 4 I use the following two overlays for SPI-0 and I2C respectively:
// i2c
fragment@0 {
target = <&spi0>;
__dormant__ {
asm330lhhx: asm330lhhx@0 {
compatible = "st,asm330lhhx";
spi-cpol;
spi-cpha;
reg = <0>;
spi-max-frequency = <10000000>;
interrupt-parent = <&gpio>;
interrupts = <13 IRQ_TYPE_LEVEL_HIGH>;
st,int-pin = <1>;
status = "okay";
};
};
};
__overrides__ {
addr = <&asm330lhhx>,"reg:0";
intpin = <&asm330lhhx>,"st,int-pin:0";
interrupt = <&asm330lhhx>,"interrupts:0";
asm330lhhx = <0>, "+0";
}
// spi
fragment@0 {
target = <&i2c_arm>;
__dormant__ {
#address-cells = <1>;
#size-cells = <0>;
status = "okay";
asm330lhhx: asm330lhhx@6b {
compatible = "st,asm330lhhx";
reg = <0x6b>;
interrupt-parent = <&gpio>;
interrupts = <26 IRQ_TYPE_LEVEL_HIGH>;
st,int-pin = <1>;
drive-pullup-shub;
status = "okay";
};
};
};
__overrides__ {
addr = <&asm330lhhx>,"reg:0";
intpin = <&asm330lhhx>,"st,int-pin:0";
interrupt = <&asm330lhhx>,"interrupts:0";
asm330lhhx = <0>, "+0";
}
Another check that you could do once the sensor is activated with iio_readdev / generic_buffer is to verify that the interrupt pin of the sensor is set (int pin number of sensor depends on "st,int-pin" property value set in device tree, default is int 1), in this case if the handler doesn't trigger it is a matter of the miss configuration of GPIO interrupt pin on the target board BSP.

I think you are right, this very much relates to configuration with board BSP. It is just I have no knowledge about it and there is no specific clue.
Anyway, I will check further. Thank you so much!!!
Besides, there is one info. for your reference.
One wierd thing is, when I execute following two i2cset commands, the data-ready interrupt will be reported endlessly and interrupt handler is called repeatedly.
/usr/sbin/i2cset -f -y -a 10 0x6a 0x12 0x44;
/usr/sbin/i2cset -f -y -a 10 0x6a 0x12 0x64;And when I again change 0x12 reg to value 0x44, the interrupt storm will be disabled.

Moreover, if "drive-open-drain" is added as following, after device probe is done, the data-ready interrupt will also be reported endlessly and interrupt handler is called repeatedly.
This time, no need to execute i2cset commands at all.

Finnally, H/W part said there is H/W issue on interrupt pins.
So I should close this issue.
Thank you!
