Its a nRF52833, just on a specific board. You can program it freely with any firmware specific to the nRF52833, but you might have to port basic features (pin outs etc).

PS: you're posting in a 4 year old thread. I would recommend that you create a new thread specific to your question.

Cheers,

My target is to build a BLE mesh formed by microbits & nrf52833.

That's why I am asking.

Also I would like to thank you for your previous answer :)

Hi,

The question is that there are not any documents about how to program It.

As you know, nRF52833 & microbit V2 has the same proccesor.

Do you know if the things done in the nRF52833 could be usted on the microbit?

Hi,

According to Segger's forum, this should be available on their website:

https://forum.segger.com/index.php/Thread/7707-SOLVED-j-link-for-BBC-micro-bit-v2/?postID=28740

Firmware and howto is available in the link in the replies in the above thread.

Kind regards,

Håkon

Hello,

I have been trying to use the microbit for a university project. I would like to program It with segger as I have done with the nrf58333.

However I dont have any reference about how yo do It.

Could you provide a basic example. I would aprecciate so much.

Besr regards :)

Fantastic :). After changing the clock source as per your link, and then increasing the SRAM Start address (The soft device raised an error about insufficient RAM) it all burst into life!

Thanks for your help.

Hi,

Getting stuck in softdevice_enable (ie: no error code return) is normally due to incorrect LFCLK source being used. I believe the microbit does not have an external 32k LFCLK, so you'll have to use the internal 32k RC oscillator instead. Here's how you configure that (in main.c::ble_stack_init()) devzone.nordicsemi.com/.../

Note: The microbit is a 256k flash and 16k RAM device, while the pca10028 is 256k/32k RAM, so you might have to adjust the RAM mapping for larger projects.
