SDK version 12, yes.

I am simply trying to follow the steps listed in this post, except using SDK 12 example files: blog.motsai.com/.../

I did generate my own private/public key pair, but perhaps it was not included correctly in the file...

Hi,

Which SDK version are you using, and which example are you trying to compile? From the error message you get, I would guess you are trying to compile a DFU exampl from SDK 12.x.0.

pk is a variable defined in dfu_public_key.c in secure bootloader. You need to generate your own private/public key pair and include it in this file, or you can use the debug projects if you just want to test the DFU with the presigned zip files in the SDK.

Best regards,

Jørgen
