We plan to use nRF52840 in our new project. But the application is likely to be larger than 500 Kbytes
So we are going to use the only one Bank flash for DFU as in following screen shot .
This means that we need to do UART DFU in mcuboot bootloader. We need to fetch new image from a Modem module by UART and write the new image into application flash area.
Most of examples in NCS SDK are using two bank DFU solution.
Would you please share us some examples and documents about UART DFU in mcuboot bootloader to give us some guidance?
By the way we are using nRF52840dk_52840 board , NCS 1.7.1 and Visual Studio code to evaluate our solution.
