Hi Jørgen,

it seems the commands changed a bit, for example now to flash a file I have to type:

 nrfjprog program --device nrf52 -c nrf52832_xxaa.hex

However, this works fine too with the pca10028.

It turned out I had an old version of the SEGGER software. Installing the latest version fixed the problem. I can now erase and flash the board fine using the pca10028, also with rknrfgo.

Hi,

I'm not sure if rknrfgo support nRF52832, but you should be able to erase/flash it using the pca10028 board and nrfjprog, which can be found in the OSX version of nRF5x Command line tools. Here is documentation about how to install it.

Commands to erase:

nrfjprog --family nrf52 --eraseall

and flash the file hex_file.hex:

nrfjprog --family nrf52 --program hex_file.hex –-chiperase

Best regards,

Jørgen

I only tried to erase the chip for now and unfortunately rknrfgo does not give any error, it just doesn't work. In particular I am using the devices Meta Motion R (store.mbientlab.com/.../).

Just for clarity, I don't want to flash nrf51 compiled code (I edited the question) and for now I only tried to erase the chip because I have no compiled code for nrf52, I will try in the following days.

Did you change the flash start and ram address accordingly? Did you change the softdevice accordingly? Not sure why you would want to use the nrf51 compiled code on the nrf52. You would be better taking that source code and compiling towards the nrf52 sdk and predefine options. That way the code to optimized and compiled to run on the nrf52.

Yes it works. Can you post more details about the error? Any screenshots, error codes? Cheers Jan
