The reason why I can't insert breakpoint is that my Keil5's version is 5.14, it' too much lower than the latest version, I change to v5.23, ererything works well.

Yes, I did call EccDemo().

Could you try to upgrade to the latest Segger J-link drivers (V6.16e) and nRF5x-Command-Line-Tools(9.6.0), and see if that solves the issue.

I use 10040, my Keil version is 5.14. Please make sure if you call the function "EccDemo()", because ecc_init doesn't call any functions in the lib file.

	uart_init();
	
	ecc_init(true);

buttons_leds_init(&erase_bonds);
ble_stack_init();
gap_params_init();
services_init();
advertising_init();
conn_params_init();

NRF_LOG_INFO("\r\nUART Start!\r\n");
	NRF_LOG_FLUSH();
err_code = ble_advertising_start(BLE_ADV_MODE_FAST);
APP_ERROR_CHECK(err_code);

	EccDemo();
	
// Enter main loop.
for (;;)
{
    power_manage();
}

static void EccDemo(void) is just above th function main()

I just tested the project you uploaded, and setting the breakpoints worked fine here:

Are you using a nRF52-DK ? What programmer/debugger are you using?

Here is my project which based on SDK12.2 ble_app_uart.rar

Of course, you should set the path of uEcc.h yourself.

The first includes lib file, the other doesn't.
