nRF52832 use device of lis2dh, Failed to read chip id

[psencao]

use the example project of lis2dh on ncs,the pin configuration of the i2c is correct,but it's can't to initialize，as follows:

Is there anything else need to configure

[helsing]

Could you please also post the complete log file?

[psencao]

a_beacon.zipthe version of ncs is v2.2.0。only use the lis2dh application,can't Initial start with no log，add the lis2dh device to beacon application,found the i2c error.

the board is dwm1001 dev,The pin has been configured as follows:

prj.conf:

.dts:

main.c:

the rttlog：

does the project have a log saved during debugging?

i use the nRF5_SDK_16.0.0 to control the lis2dh and it's normal

thank you

Thank you for the additional information. If you are able to probe the pins to look for activity it would speed up the search for the error. I will in any case look for other possible ways to find the error.

The pins of both sda and scl have no signal change and are always low，the 

compatible of i2c configure as twi or twim，it's the same error log

Hi, 

I'll be taking over this case as Håkon is out-of-office,

Can you clarify if the standard unmodified LIS2DH sample works on your board? This means without merging it with the beacon sample? 

Have you modified the pins that are used in the sample, if so what pins are you using?

it's also Unable to initialize：

The pins of both sda and scl have no signal change and keep low level

Hi,

Ok, so you're not able to run the unmodified lis2dh sample on your board?

Have you checked the log? What error message do you get?

regards

[psencao]

where is the debug log?this is the error message:

[Jared]

Hi,

Have you modified the pins that the sample is using? Can you share the schematic of the module that you're using?

the i2c pins' schematic as follows
