Hi Eugene

There are various loaders for the K82 at the link below and full code showing how all of these details are done is in the uTasker project on Git Hub - including simulation of the process.
See the appendix in the serial loader document for a check list of things to consider to ensure application's boot loader compatibility.

Regards

Mark
