SNOC BRKWS20 board programmation

[Crazyday]

Does anyone used nRF52 for programming a SNOC BRKWS20 board ? Can you explain me how to proceed ?

Have you asked Sigfox? 

How is this module normally supposed to be programmed/debugged?

Do you have a datasheet for the SNOC BRKWS20?

The product page says "A 10-pin connector has been provided to allow programming of the built-in ARM Cortex M4F processor". If that refers to the nRF52832 and the 10-pin connector is a standard ARM 10-pin debugger connector then you'd only need a 10-pin cable between the nRF52 DK and the Sigfox module.

I want to reprogram the microcontroller on the BRKWS20 board.

According to the documentation, it's a nrf chipset. 

I compile the project segger studio and I connect P19 and the pin on BRKWS20 board, like it's described on documentation.

I don't find how to deploy code on sigfox board. Can you help me please ?

Thank you,

Alexandre

I could not find the documentation for that device, can you provide a link?

The Breakout card is a support card of the Wisol module and does not add any active features.

The Wisol module is the heart of the system and is relatively complex because it includes the processor, memory, radio modules,...

It is programmed thanks to the manufacturer's SDK delivered on the Github, which includes the management of the various modules and the support of firmware integrated in certain chips. It is possible to do without it, but it is much more complex.

Please note that it is not a stand-alone module with an integrated processor.

The development environment implementation guide is here:

"I don't find how to deploy code on sigfox board. Can you help me please ?"

That's Sigfox's product on not ours. I can help you program the nRF52, but not the Sigfox device.
