nrf_drv_clock_init()

[daman_kaur86]

.\_build\nrf52840_xxaa.axf: Error: L6218E: Undefined symbol nrf_drv_clock_init (referred from main.o).
.\_build\nrf52840_xxaa.axf: Error: L6218E: Undefined symbol nrf_drv_clock_lfclk_request (referred from main.o).
Not enough information to list image symbols.
Not enough information to list load addresses in the image map.

i am getting this error. Got to know that this can be due to the incorrect paths, but paths provided are correct.

how to debug this? as i am working on nrf52840 DK

Hi,

Have you added the nrf_drv_clock.c file to your project? And set NRF_CLOCK_ENABLED to 1 in the projects sdk_config.h?

i have added the nrf_drv_clock.c but unable to find NRF_CLOCK in sdk_config.  its not there in the sdk_config.h

Was a small typo in my last response. If you can't find it, add these clock settings to the sdk_config.h:

// <e> NRF_CLOCK_ENABLED - nrf_drv_clock - CLOCK peripheral driver - legacy layer
//==========================================================
#ifndef NRF_CLOCK_ENABLED
#define NRF_CLOCK_ENABLED 1
#endif
// <o> CLOCK_CONFIG_LF_SRC  - LF Clock Source
 
// <0=> RC 
// <1=> XTAL 
// <2=> Synth 
// <131073=> External Low Swing 
// <196609=> External Full Swing 

#ifndef CLOCK_CONFIG_LF_SRC
#define CLOCK_CONFIG_LF_SRC 1
#endif

// <o> CLOCK_CONFIG_IRQ_PRIORITY  - Interrupt priority
 

// <i> Priorities 0,2 (nRF51) and 0,1,4,5 (nRF52) are reserved for SoftDevice
// <0=> 0 (highest) 
// <1=> 1 
// <2=> 2 
// <3=> 3 
// <4=> 4 
// <5=> 5 
// <6=> 6 
// <7=> 7 

#ifndef CLOCK_CONFIG_IRQ_PRIORITY
#define CLOCK_CONFIG_IRQ_PRIORITY 6
#endif

// </e>

after including this piece of code, i got more errors

Can you try setting this NRFX_CLOCK_ENABLED to 1 if it aren't set to 1 already?

Got to know that this can be due to the incorrect paths, but paths provided are correct.

How did you include the paths and what is your path?
