Failure of i2c LIS2DH_GetWHO_AM_I continuously resets the device every time in DA14531

Question

Hi , 
 i am using da14531 its our custom hardware , we have i2c communication using LIS2DH accelerometer , some faults occured in hardware related to i2c communication while reading LIS2DH_GetWHO_AM_I on failure case device continuously resetting the device, but on the same faulty hardware if i do flash the program without i2c communication its working fine, 
 the case i am expecting is on failure i should not reset the device , it should work with the other functionalities. how to resolve this ?

Thanks ,

Hi Sowmiya, Thank you for posting your question online. Please attach the debugger while your application is running on the custom board so we can see where exactly it crashes. If it constantly resets, it means that there is either a Heap Exhaustion issue and the device resets or the WatchDog expired and caused the reset. Please refer here on how to attach the Debugger via Ozone: Tutorial Dialog SDK 6.0.x Debugging &mdash; DA145XX Tutorial SDK Getting started (renesas.com) Please also refer on our Git example we have with the LIS2DH accelerometer: BLE_SDK6_examples/interfaces/SPI_or_I2C_DMA_accelerometer at main &middot; dialog-semiconductor/BLE_SDK6_examples (github.com) Best Regards, OV_Renesas
