I tested your code and I was able to use RTT logging without any problems. Could you point to what specifically goes wrong?

Best regards,

Simon

Hi, Simon.

Thank you for answer.

I resolved to combine two example(spi + timer).

It is working well.

But there are strange point.

I have used TIMER 4 now.

If I enabled TIMER4 single, It is not working. But when I enabled two timer, it is working well.

or, when #define TIMER4 4, working well (Not #define TIMER4 1)

I think it is strange.

I m wating for your answer.

This is timer code in sdk_config.h. (example spi base)

--- When working.

// <q> TIMER0_ENABLED - Enable TIMER0 instance

#ifndef TIMER0_ENABLED
#define TIMER0_ENABLED 1
#endif

// <q> TIMER1_ENABLED - Enable TIMER1 instance

#ifndef TIMER1_ENABLED
#define TIMER1_ENABLED 0
#endif

// <q> TIMER2_ENABLED - Enable TIMER2 instance

#ifndef TIMER2_ENABLED
#define TIMER2_ENABLED 0
#endif

// <q> TIMER3_ENABLED - Enable TIMER3 instance

#ifndef TIMER3_ENABLED
#define TIMER3_ENABLED 0
#endif

// <q> TIMER4_ENABLED - Enable TIMER4 instance

#ifndef TIMER4_ENABLED
#define TIMER4_ENABLED 1 (or #define TIMER0_ENABLED 0, #define TIMER4_ENABLED 4)
#endif

// </e>

--- When not working.

// <q> TIMER0_ENABLED - Enable TIMER0 instance

#ifndef TIMER0_ENABLED
#define TIMER0_ENABLED 0
#endif

// <q> TIMER1_ENABLED - Enable TIMER1 instance

#ifndef TIMER1_ENABLED
#define TIMER1_ENABLED 0
#endif

// <q> TIMER2_ENABLED - Enable TIMER2 instance

#ifndef TIMER2_ENABLED
#define TIMER2_ENABLED 0
#endif

// <q> TIMER3_ENABLED - Enable TIMER3 instance

#ifndef TIMER3_ENABLED
#define TIMER3_ENABLED 0
#endif

// <q> TIMER4_ENABLED - Enable TIMER4 instance

#ifndef TIMER4_ENABLED
#define TIMER4_ENABLED 1
#endif

// </e>

Sincerely yours

Eric

Follow these steps:

Put in all the timer related code into your SPI example. Like functions, variable declarations and macros.
Add #include "nrf_drv_timer.h" at the top of your SPI example
If you're going to implement the SoftDevice later on you should use timer1 or timer2, not timer0
Add all the timer related configurations to sdk_config.h
- In the sdk_config.h file of examples\peripheral\timer, copy the defines belonging to "//<e> TIMER_ENABLED - nrf_drv_timer - TIMER periperal driver - legacy layer"
Add <..>\modules\nrfx\drivers\include\nrfx_timer.h to the path
Add the source file of the nrfx driver to project explorer (\modules\nrfx\drivers\src\nrfx_timer.c)

I've provided an example down below.

Best regards,

Simon

What do you mean by that?

What debugging have you done to find the problem?
