I2C interface with nrf52 sdk v9.2 hardfault error

[babatola]

I am designing an device and i need to communicate with the device using the I2C of my nrf52.

when ever i try to initiate the transfer process using the driver function -nrf_drv_twi_tx i get a hardfault error. the exact code is below

nrf_drv_twi_tx(&i2c1_master_instance, I2C_ADDRESS, TransmitBuffer, data_size, true) != NRF_SUCCESS)

i get a hardfault error and the event handler does not get called

I am using a pca10040 development board.

I have checked on my codes and i cannot find any fault in it.

Thanks
