My First test with nRF52840 on MS04SF7_V1.0 (from Minew dongle)

[ramon]

I have follow the nordic documentation but I can not get the blinky example on the dongle nRF52840

Why not?

Hi

I was not able to find a Dongle/module by Minew called MS04SF7. Do you refer to the MS88SF2 module? Could you provide a link to the product page or datasheet?

Best regards,

Simon

So which documentation, exactly, did you follow?

Give a link.

As Torsten Robitzki asked - why not?

What, exactly, did you try? What happened when you did that? Were there any error messages? etc, etc, ... ?

Note that the Dongle is not recommended for doing development - you would be far better to use a Development Kit (the clue is in the name).

Thanks

 

I have the dongle from minew, with nRF52840 chip.

this the error on nRFconnect writing the hex file from SDK

First, it seems like you are trying to flash data, that has overlapping regions. Which means, your hex file(s) describe the content of single flash byte at least two times.

Second, to be able to use nrf connect to flash new firmware onto the dongle, without a SWD adapter, there have to be a suitable bootloader on it. You can either use tag connect cable to connect your dongle to a SWD adapter (your first picture) or you have to lookup the documentation for your dongle, if there is already a bootloader and how to use it.
