I have had great success developing a project based on the peripheral_uart sample. Now I am trying to add DFU over UART to that project. Specifically, I would like to add DFU over UART such that the application core image and network core image can both be updated by non-simultaneous updates (so that external flash memory is not needed). I have read all the documentation I can find, but I am still unsure how to get this to work. I would appreciate some guidance from the Nordic experts.
I am working in VSCode on Windows 10 with the nRF Connect SDK version 2.6.0. My build target is the nRF5340DK version 2.0.2.
