DFU over UART #nrf52832
I'm trying to build an app that can be upgraded over UART. I see the smp_svr sample has an example of doing this over BT, and I could get that to work.
I've tweaked the prj.conf to add the line
I've also disabled CONFIG_MCUMGR_SMP_BT just to prevent things from getting confusing.
My nrf52 has an mcuboot which was obtained from https://github.com/runtimeco/mcuboot
I then sign and build my modified smp_svr image and then flash it to the device.
I see the following on console
the console, however is read only - I cant access the shell. This is all on the nRF52 dev board.
I'm using Ubuntu 18.04 as my host environment.
1. Is there some step I'm missing to allow device upgrades over UART?
2. Do I need to do anything in particular for 2-way access to the shell
For reference, my prj.conf is:
Thanks in advance..
