Hello,
As a summary (described fully below) I have loaded the ble_app_hrs example onto my device and its not working right as LEDs that should light up don't and the program is getting stuck in a HardFault_Handler.
%%%%%%% BACKGROUND %%%%%%%
So I'm using:
- nRF6310 with a PCA10006 and J-Link Lite CortexM (nRFgo Starter Kit)
- nRFgo Studio v 1.21.2.10 and programming a S110v7.0.0 SoftDevice onto the board via nRFgo Studio
- ARM Keil v5 with legacy fix.
I am working from the nRF51822 Development Kit User Guide v1.3 and have reached the heart rate monitor example ble_app_hrs which I've accessed from the directory "Nordic\nrf51822\Board\nrf6310\ble_s110_serialization\ble_app_hrs\arm\ble_app_hrs.uvproj"
I have managed to successfully program the S110 soft Device as shown in the picture below.
In Keil I can then successfully Flash the device with the compiled ble_app_hrs. I am targeting a nRF51822_xxaa board. The Build Output is given as;
Load "C:\\Keil_v5\\ARM\\Device\\Nordic\\nRF51822\\Board\\nrf6310\\ble_s110_serialization\\ble_app_hrs\\arm\\_build\\ble_app_hrs.axf"
Set JLink Project File to "C:\Keil_v5\ARM\Device\Nordic\nRF51822\Board\nrf6310\ble_s110_serialization\ble_app_hrs\arm\JLinkSettings.ini"

%%%%%%% PROBLEM %%%%%%%
Once I have flashed the device I immediately recognise my first problem - the nRFgo Motherboard does not light up LED0 to show advertising which should happen as described in the ble_app_hrs main.c
int main(void)
{
APP_GPIOTE_INIT(1);
connectivity_chip_reset();
leds_init();
buttons_init();
timers_init();
ble_stack_init();
bond_manager_init();
scheduler_init();
gap_params_init();
advertising_init();
services_init();
sensor_sim_init();
conn_params_init();
sec_params_init();
// Start execution
application_timers_start();
advertising_start();
// Enter main loop
for (;;)
{
app_sched_execute();
power_manage();
}
}
static void leds_init(void)
{
nrf_gpio_cfg_output(ADVERTISING_LED_PIN_NO);
nrf_gpio_cfg_output(CONNECTED_LED_PIN_NO);
nrf_gpio_cfg_output(ASSERT_LED_PIN_NO);
}
static void advertising_start(void)
{
uint32_t err_code;
err_code = sd_ble_gap_adv_start(&m_adv_params);
APP_ERROR_CHECK(err_code);
nrf_gpio_pin_set(ADVERTISING_LED_PIN_NO);
}
Shown is my nRFgo motherboard while it's meant to be running the program.
So I decided to go ahead and debug the code. What I've found is that whenever I debug the program and run it then stop it's always getting caught in a HardFault Hander in arm_startup_nrf.s.
HardFault_Handler\
PROC
EXPORT HardFault_Handler [WEAK]
B . //GETS CAUGHT HERE
ENDP
So I'm not sure what is going wrong. I've been struggling to use this nRF6310 to get this basic example working for 3 days now and I encounter problem after problem if someone could help I would be immensely grateful.
Thank you for your time.
