[Error] bbc_microbit_v2 building error for lis2dh

[Liviu112]

lis2dh_output.txt

Describe the bug
Error while building the example lis2dh, it works for bbc_microbit but not for bbc_microbit_v2.
I have tried to find the issue, but I have no luck, one thing which might cause some problems is that the sm303agr-magn@1e and lsm303agr-accel@19 from the bbc_microbit_v2.dts file are on the same GPIO pin.

To Reproduce
Steps to reproduce the behavior:

1. zephyr 2.4
2. cd zephyr/samples
3. west build -b bbc_microbit_v2 samples/sensor/lis2dh
4. See the error

Expected behavior
Bbc_microbit (v1.5 and v2) share the same accelerometer lsm303agr it is expected for the same code to work, or a solution to access the accelerometer for v2.

Impact
Not able to progress on my FYP (Final year project) because I can not access the accelerometer information.

There are 300 lines, I have attached the file lis2dh_output.txt for the full output.

Environment (please complete the following information):

• OS: Linux 20.04
• Toolchain: Zephyr version: 2.4.0, west 0.9

Additional context
The bbc_microbit (v1.5) has the Cortex-M0 processor while v2 has the Cortex-M4 processor, I am not sure if that should make any difference in the ability to use the example lis2dh.

On the micro:bit v2, the accel/magn sensors share the same interrupt line. P0.25 is the COMBINED_SENSOR_INT, see https://tech.microbit.org/hardware/schematic/

I have a micro:bit v2 and will try out the sample.

Thanks, I really appreciate it, also, the same error will occur on Zephyr v2.5. I have brunch the bbc_microbit_v2 to Zephyr 2.4.

Sorry about the delay.

It looks like it's a bug on the microbit v2. I got the same error. The sample code works fine with the same sensors on the nRF52840 & STM32 devices.
