nrf_drv_twi_enable(&m_twi) error

[arshdeep]

Hi,

I am getting this error when enabling the twim instance. It initializes successefully but throws error when enabling it. 

How can I troubleshoot it further to know the exact issue? What does this error code mean?

<error> app: ERROR 3735928559 [Unknown error code] at C:\nRF5_SDK_15.0.0_a53641a\examples\ble_peripheral\nRF5_SDK_15.3.0_59ac345\modules\nrfx\drivers\src\nrfx_twim.c:273
PC at: 0x000331AF
<error> app: End of error report

Using nrf2840 with SDK 15.3.0 

Thanks,

Hi,

On line 273 of nrf_twim.c, you can find a line checking if the driver is initialized:

NRFX_ASSERT(p_cb->state == NRFX_DRV_STATE_INITIALIZED);

Error 3735928559 translates to 0xDEADBEEF in hex, which indicates an assert happened. 

Looks like you have not initialized the driver before calling the enable function. Please have a look at the function nrfx_twim_init().

Best regards,
Jørgen
