RE: nRF52810 bootloader SDK 16/17

Hello,

The oberon library has a larger memory footprint compared to uECC. which means you will have to allocated more flash the bootloader compared to the standard configuration. Assume you may have done that already. there was a bug in flash_placement.xml for the SDK 16 bootloader that made it possible to build the bootloader even if you had overlapping flash sections.

Please try to do a complete re-build of the bootloader with the flash placement file copied from SDK 17.0.2 below. I expect you will get a linker error if your bootloader is too big.

[quote user=""]I am also willing to change to SDK17, but I found no entry for the --sd-req in the nrfutil when preparing the zip file, is it still unsupported?[/quote]

The list is not always up to date, but that doesn't mean it's not supported. You can find the FWID listed in the SD release notes.
