Just run the installer. Power the board on/off, and open e.g. nRFGo Studio, you should get an automatic pop-up like this:

Thanks for all great help.

Is there any tutorial about how to update the version of on-board segger jlink on nRF52840-PDK by using Command Line Tools on windows?

Support for nRF52840/PCA10056 was first added in J-Link V6.12c. Download link here.

Download the J-Link Software and Documentation Pack

You should also use the the latest nRF5x-Command-Line-Tools. Download link here.

It seems that the code does not reach that line and stick somewhere before.

I think I found the problem. I am using on-board J-Link which its software does not support NRF52840_XXAA and it selected ARM7 by mistake. Not sure if I select NRF52832_XXAA would work efficiently or I should update the version of the J-Link software. It is V5.12f on my nRF52840-PDK. Could you let me know which one would be helpful?

Thank you.

Why are you getting "APP:INFO:Blinky example started." from the terminal, when you are printing "SAADC HAL simple example" ? Looks like you have not flashed the SAADC code, and that the Blinky example code on the chip.

Could you open nRFGo studio or use nrfjprog, and do an "erase all" , and then flash the code to the chip ?

trying Step Into, IAR ignores it and the code sticks. So I can not follow code. It seems that the example does not go to the end.

I have chosen nRF52840 as my device but in debug log is showing ARM7.

It seems I missed something in IAR settings. Could you please help me?

Sorry for not using the forum efficiently. It seems I am not posting in a right way.

I am using the exact sample code of SDK13-> peripheral -> saadc. Some part of it:

enter code here

int main(void) { uint32_t err_code = NRF_LOG_INIT(NULL); APP_ERROR_CHECK(err_code);

err_code = nrf_drv_power_init(NULL);
APP_ERROR_CHECK(err_code);

ret_code_t ret_code = nrf_pwr_mgmt_init();
APP_ERROR_CHECK(ret_code);

NRF_LOG_INFO("SAADC HAL simple example.\r\n");
saadc_init();
saadc_sampling_event_init();
saadc_sampling_event_enable();

while (1)
{
    nrf_pwr_mgmt_run();
    NRF_LOG_FLUSH();
}

}

Could you post the code you use?

I just get this outputs: "APP:INFO:Blinky example started." and ":ERROR:Fatal"

Ok, are you getting any output from the terminal? Normally you should get something like this:

APP:INFO:ADC event number: 12
APP:INFO:21
APP:INFO:20
APP:INFO:22
APP:INFO:22
APP:INFO:24

Hi,

Make sure that you generating debug information. See this post. Then in the "Optimizations" tab, set the optimization to None. In the Preprocessor tab, add the symbol DEBUG under "Defined symbols".
