RBC mesh timer 0 usage

[victor]

Hi I am using the RBC mesh "github.com/.../nRF51-ble-bcast-mesh", sd_110_7.1 and sdk_6.2

The rbc mesh is using timer0 as well as the softdevice. I removed the app timers from my project so it compiles and works but there is a problem.

It craches after some time due to timer0 beeing protected by the MPU and write reqests beeing sent from the rbc mesh to timer0 peripheral which results in hardfaults.

What can I do to fix this? Also problem occures when writing to PPI but this can be fixed by running ppi accesses through the sd_ppi api.

For example my code halts here (timer_control.c):

void timer_abort(uint8_t timer_index){
if (timer_index < 4)
{
    [HERE] NRF_TIMER0->INTENCLR = (1 << (TIMER_INTENCLR_COMPARE0_Pos + timer_index));
    active_callbacks &= ~(1 << timer_index);   
    NRF_PPI->CHENCLR = (1 << (TIMER_PPI_CH_START + timer_index));
    never_used_bitmap |= (1 << timer_index);
}}

And NRF_MPU->PERR0= 0xc300f903

that's interesting, thanks trond-snekvik!
