I'm sorry but it's still not very clear for me.

Are you saying you only want to update part of the firmware code, leaving other part un-touched. Say first 1kB of the code, and keep the rest 30kB for example un-modified ?

It's not possible to do that with our current DFU bootloader. But it should be straight forward to modify the bootloader to do that. There is a small tricky part that for a page that only partly updated you would need to backup the part that should be kept, erase the page, write the new data in and then write the backup data back.

If you don't want to modify the bootloader, I would suggest to simply update the whole thing, meaning you only modify the first 1kB but in the new image you update the whole 31kB.

Hi, Could you explain a little bit more on what you want to update and what you don't want to ? You can have a look at this layout, you can put the data you don't want to update in Application Data area.
