Yes, it should be nrf52, although it works when this option is chosen. Looks like a typo or copy-paste error.

The Keil example provided in the link for nRF52810 in SDK v15 works fine, thank-you. (probably an SES s112 version in the next sdk release).

To your questions, ....1) the bootloader was built using what was in 14.2 zip file, SD v5.1, .....2) I gave SD v6 a try in sdk 14.2 since I used SD v6 for my app, and it did not work.

I noticed that for nrfutil pkg generate I used --sd-req 0xA7 for SD s112, but the entry in the Github entry had

s112_nrf51_6.0.0 0xA7

Should it not be nfr52?

-thank-you

In addition, my coworker Vidar has uploaded an example for bootloader for nRF52810 in SDK v15 here. Please try.

Hi Simon,

Could you send us your .zip file also the scrip you used to generate the .zip file ? I suspect the SD version was not correct ?

I suspect you can't debug and got issue with failed to halt process , could be because of the configuration of the start address of the bootloader. Could you double check if it's configured correctly ?

Which softdevice and which SDK you used to build your bootloader ?

What do you mean by "SD v6.0 in the 14.2" ? We only have v5.0 in SDK v14.2
