Problems with programming a third-party nRF51822 board

Yes, we have many non-SD examples in our SDK, mostly peripheral driver and library examples, see <SDK folder>\examples\peripheral

Regarding SoftDevices, can you run programs without any SoftDevice at all?

OK, sorry - that wasn't clear.

That's why the forum has the 'Quote' feature.

Dear awneil, I tried to be nice by answering your question "Any particular reason for starting with nRF51?".

I haven't created a new question because I found the solution, If anyone is interested, check this: https://devzone.nordicsemi.com/f/nordic-q-a/10151/gcc-blinky-project-generated-hex-file-not-working/37652#37652

Thank you for your help.

Regards

Which part of "create a new question" did you not understand?

Thank you for your support, I need integrate installed beacon's network based on nRF51822, with new custom beacons based on nRF52832.

I tested development on nRF52832 without issues (SDK v15.3 + GCC) it's perfect, but I need make some developments on nRF51822, I want to use most recent compatible SDK v12.3.

This the reason because I need learn how to program over nRF51822, it's mandatory for me.

That seems to be the only thing that your post has in common with the rest of this 5-month-old thread?

Best to start your own thread rather than hijack an unrelated one.

Any particular reason for starting with nRF51 ?

Especially as nRF51 is not recommended for new BLE projects:

https://devzone.nordicsemi.com/f/nordic-q-a/42960/status-of-nrf51-products/169728#169728

You'd make your life easier using a Nordic Dev Kit - See:

https://devzone.nordicsemi.com/f/nordic-q-a/49079/nrn51822-not-reconized/195385#195385

How to properly post source code:

(also for stuff like makefiles, logs, etc)

Hi, I new in Nordic products too, my board is BLE400 (nRF51822 based) from www.waveshare.com/.../BLE400.
I testing Blinky example in SDK 12.3.0 via GCC, compilation it's correct, load via bnRFGo v1.21.2.10 it's correct too, but nothing happend.
Could you please help me?

Thanks in advance.

RE: Problems with programming a third-party nRF51822 board

bjorn-spockeli — Thu, 17 Jan 2019 08:26:42 GMT

Yes, the nRF51422 and nRF51822 are identical in terms of hardware. The only difference is that you will only be able to run the ANT protocol on the nRF51422, not the nRF51822. If you plan on using Bluetooth only then you can use both.

RE: Problems with programming a third-party nRF51822 board

ImanH — Thu, 17 Jan 2019 05:55:13 GMT

The examples in SDK 12.3 are for nRF51422. Can I use them for nRF51822?

RE: Problems with programming a third-party nRF51822 board

bjorn-spockeli — Wed, 16 Jan 2019 14:51:55 GMT

I recommend using an example from the nRF5 SDK v12.3.0 ( the latest version that supports the nRF51 series), e.g. the Blinky Example.

RE: Problems with programming a third-party nRF51822 board

ImanH — Wed, 16 Jan 2019 13:51:04 GMT

Thanks Bjørn,

I created a new project in Keil:

the main.c code:

#include <stdlib.h>
#include "nrf_delay.h"
#include "nrf_gpio.h"


	const uint32_t led_pin1 = 0;

 int x = 0;
int main(void)
{
	
	nrf_gpio_cfg_output(led_pin1);
	nrf_gpio_pins_clear(led_pin1);
	
	
	while (true)
	{
		
		x++;
	nrf_gpio_pins_toggle(led_pin1);
	nrf_delay_ms(500);
	}
	
	
	
}

The project is compiled and flashed successfully but nothing happens. Neither LED blinks nor x variable increments in debug mode.

What should I do?

RE: Problems with programming a third-party nRF51822 board

bjorn-spockeli — Wed, 16 Jan 2019 12:53:35 GMT

Hi Iman,

You cannot use ST-Link programmers with nRFGo Studio or our command line tool nrfjprog as they only work with Segger J-Link programmers. You can use Keil to flash firmware with ST-Link programmers, see this blog post. Another approach is to use OpenOCD, see this post. Lastly, you could also take a look at this post.

PS: You need to use the S130 SoftDevice for the nRF51, not the S112 which is for the nRF52832 and nRF52810.

Best regards
Bjørn
