52840 LE CODED App_UART with GPIOTE - crash

[Avi]

The code is running on 52832 (BLE) and transmit msg over BLE (NUS) each time GPIO is active (GPIOTE).

But same code (after adding LE CODED Phy) is crashing once it reached the GPIOTE initialization 

What can be the problem?

here is my main code:

int main(void)
{
bool erase_bonds;
uint32_t err_code;
// Initialize.
//uart_init();
log_init();
NRF_LOG_INFO("Start");
timers_init();
buttons_leds_init(&erase_bonds);
power_management_init();
ble_stack_init();
gap_params_init();
app_timer_start(bas_timer, APP_TIMER_TICKS(20* 1000), NULL);
gatt_init();

services_init();
advertising_init();
conn_params_init();
err_code = sd_ble_gap_tx_power_set(BLE_GAP_TX_POWER_ROLE_ADV, m_advertising.adv_handle, TX_POWER);
APP_ERROR_CHECK(err_code);
if (!nrf_drv_gpiote_is_init())
{
err_code = nrf_drv_gpiote_init();
VERIFY_SUCCESS(err_code);
}
nrf_drv_gpiote_in_config_t in_config = GPIOTE_CONFIG_IN_SENSE_HITOLO(true);
in_config.pull = NRF_GPIO_PIN_PULLUP;
err_code = nrf_drv_gpiote_in_init(PIN_IN1, &in_config, in_pin_handler1);
APP_ERROR_CHECK(err_code);
err_code = nrf_drv_gpiote_in_init(PIN_IN2, &in_config, in_pin_handler2);
APP_ERROR_CHECK(err_code);
err_code = nrf_drv_gpiote_in_init(PIN_IN3, &in_config, in_pin_handler3);
APP_ERROR_CHECK(err_code);
err_code = nrf_drv_gpiote_in_init(PIN_IN4, &in_config, in_pin_handler4);
APP_ERROR_CHECK(err_code);
err_code = nrf_drv_gpiote_in_init(PIN_IN5, &in_config, in_pin_handler5);
APP_ERROR_CHECK(err_code);

nrf_drv_gpiote_in_event_enable(PIN_IN1, true);
nrf_drv_gpiote_in_event_enable(PIN_IN2, true);
nrf_drv_gpiote_in_event_enable(PIN_IN3, true);
nrf_drv_gpiote_in_event_enable(PIN_IN4, true);
nrf_drv_gpiote_in_event_enable(PIN_IN5, true);

// Start execution.
//printf("\r\nUART started.\r\n");
NRF_LOG_INFO("Debug logging for UART over RTT started.");
advertising_start();

After debug, I can see that I reach a warning of RAM size and then next line it crashes.

If it is RAM issue, how do I know which values should I use:

// Start of RAM, obtained from linker symbol.
uint32_t const app_ram_start_link = *p_app_ram_start;

ret_code_t ret_code = sd_ble_enable(p_app_ram_start);
if (*p_app_ram_start > app_ram_start_link)
{
NRF_LOG_WARNING("Insufficient RAM allocated for the SoftDevice.");

NRF_LOG_WARNING("Change the RAM start location from 0x%x to 0x%x.",
app_ram_start_link, *p_app_ram_start);
NRF_LOG_WARNING("Maximum RAM size for application is 0x%x.",
ram_end_address_get() - (*p_app_ram_start));
}

This warning means you have to adjust the RAM settings in your linker settings. The debug log should tell you what settings to use.

What IDE/toolchain are you using?

I am using Keil

In segger I get this: 

00> <info> app_timer: RTC: initialized.
00>
00> <error> app: Fatal error
00>

Thanks for confirming. You can adjust the IRAM settings in "options for target", but I'm not sure why the RAM settings are not displayed in your log output.

Please try to add the "DEBUG" flag to your pre-processor list to see if you can get a more verbose error message.

Memory layout settings

Adding DEBUG flag

I assume Segger will be easier for debugging and adjusting RAM size.

How to do it since I am not able to reach the lines that suggest RAM size in softdevice

There is no option for breakpoints there

[Vidar Berg]

You should get the same output with Keil. Did you try to build the application with the DEBUG flag? This should replace the "Fatal error" message with a more detailed crashlog.
