nRF5 Mesh serial and serial DFU merge

Hi Nordic,

I am trying to merge nrf5 mesh serial and serial DFU, I have added serial DFU to serial mesh example, it is compiled successfully and do not show any errors in debugging. But when I start DFU it gets stuck after port open, echo and flash erase step.

I want to know proper process to merge both firmwares.

I am using :-

nrf5 SDK v16.0.0

mesh SDK v4.2.0

Thanks and regards
