hello there,
I use currently 'ble_app_hids_keyboard_s132_spi_pca10040' app of SDK11 for my nrf52832_xxaa device on 'IAR' IDE. It utilizes sofdevise s132. I do not use the evaluation board.
The nrf52 soc does not have an external 32KHz cyrstal for the LFXO oscillator, only an external 32MHz cyrstal for the HFXO oscillator. I try to set the RC oscillator. my purpose right now is only to be able to debug a simple app that flickers a led.
first of all here is what the 'nrfgo studio' shows about the memory occupancy concerning the softdevice and app: nrfgo_details.jpg
it is stated cleary that sofdevice occupies 124kB, and that the starting address of the app is 0x1f000. this is how I wrote these details in the 'Linker Configuration file editor' of the IAR: linker1.jpg
In addition, I use 0 level optimizatoin.
Here is how I wrote my simple app, without the use of ble transmission:
int main(void)
{
bool erase_bonds;
// uint32_t err_code;
NRF_CLOCK->EVENTS_HFCLKSTARTED = 0;
NRF_CLOCK->TASKS_HFCLKSTART = 1;
while(NRF_CLOCK->EVENTS_HFCLKSTARTED == 0) { /* Do nothing */ }
// NRF_CLOCK->LFCLKSRC = (CLOCK_LFCLKSRC_SRC_Synth << CLOCK_LFCLKSRC_SRC_Pos);
// NRF_CLOCK->EVENTS_LFCLKSTARTED = 0;
// NRF_CLOCK->TASKS_LFCLKSTART = 1;
// while(NRF_CLOCK->EVENTS_LFCLKSTARTED == 0) { /* Do nothing */ }
// Initialize.
app_trace_init();
timers_init();
buttons_leds_init(&erase_bonds);
ble_stack_init();
scheduler_init();
// device_manager_init(erase_bonds);
// gap_params_init();
// advertising_init();
// services_init();
// sensor_simulator_init();
// conn_params_init();
// buffer_init();
nrf_gpio_cfg_output(27);
nrf_gpio_pin_set(27);
// Start execution.
// timers_start();
// err_code = ble_advertising_start(BLE_ADV_MODE_FAST);
// APP_ERROR_CHECK(err_code);
// Enter main loop.
for (;;)
{
// app_sched_execute();
// power_manage();
nrf_gpio_pin_clear(27);
nrf_delay_ms(300);
nrf_gpio_pin_set(27);
nrf_delay_ms(300);
}
}
I try to debug but it stuck each time. what couild I amend?? and why does it is written explicaly in the SDK11 original 'ble_app_hids_keyboard_s132_spi_pca10040' app that the ROM of the app(not including softdevice) starts at 0x0??
