create timer hardfault

[frogofmagic]

Hi, I'm porting my project from SDK8.1 to SDK10 and got a problem in app_timer.c

Main chip :nRF51822 QFACA1

Crystal:32Mhz, no 32.768

1. Initial is fine. APP_TIMER_INIT(APP_TIMER_PRESCALER, APP_TIMER_OP_QUEUE_SIZE, NULL);

   APP_TIMER_PRESCALER = 0; APP_TIMER_OP_QUEUE_SIZE = 19;

2. When enter to err_code = app_timer_create(&a4wp_sm_ptu_start_timer_id, APP_TIMER_MODE_SINGLE_SHOT, m_a4wp_ptu_start_timer_handler);

   I step run into app_timer_create , when i run "p_node->is_running = false;" It jump to "void HardFault_Handler()"

3. app_timer_id_t a4wp_sm_ptu_start_timer_id; will this be a problem?

Is there anything I should modify in my code?

Hi,

you need to replace

app_timer_id_t a4wp_sm_ptu_start_timer_id; 

with

APP_TIMER_DEF(a4wp_sm_ptu_start_timer_id);

Macro additionally allocates memory for timer instance. For details check out app_timer documentation: http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk51.v10.0.0/lib_timer.html?cp=4_1_0_3_25
