https://devzone.nordicsemi.com/f/nordic-q-a/50895/firmware-update-using-another-mcuHello, I have a nordic nrf52840 on board, with another MCU (Cortex-M4) on board. Both chips are connected over UART. I want to use the Cortex chip to perform firmware update of the Nordic chip over UART. What is the best approach to do this?
