Change from ESB to Gazell

[panduro]

HI 

We have a running product that we want to improve by moving from ESB to Gazell. 

it should be an easy task, because it is only a simple main file that needs to be replaced, so I have taken as my starting point a Gazell example.

But I've run into a little problem that I hope you can help with.

I get this error:
. \ _ build \ nrf52840_xxaa.axf: Error: L6200E: Symbol TIMER0_IRQHandler multiply defined (by nrf_flywheel.o and nrfx_timer.o).

I understand what the error means and what to do normally, but I'm a little skeptical here, because I do not use nrf_flywheel. *.

so I hope you have a suggestion ..

best regards...

Hi,

  

I get this error:
. \ _ build \ nrf52840_xxaa.axf: Error: L6200E: Symbol TIMER0_IRQHandler multiply defined (by nrf_flywheel.o and nrfx_timer.o).

The gazell library has two options for which resources it uses, which is listed here:

https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/gzll_02_user_guide.html#gzll_resources

 

In your case, both gazell and nrfx_timer tries to use the same timer, NRF_TIMER0. You can fix this by changing the timer used by nrfx_timer (ie: NRF_DRV_TIMER_INSTANCE(1)).

Be sure to enable the instance in your local sdk_config.h as well (define NRFX_TIMERx_ENABLED).

 

Kind regards,

Håkon

Thanks, the problem was in the sdk_config.h..
