NRF52832 Firmware Upgrade using Esp8266

[Vaibhav_Bansal]

Hi Team

I am trying to implement the firmware upgrade for master controller nrf52832 on chip using esp8266 over uart and I am very new with this boot-loader part.

I had gone through many examples and trying to understand the flow from where to start. Code had already implementation of DFU using nrf connect application and working, but now I need to do this using esp8266.

My flow is I will download the hex file from the server and then upgrade the hex file form esp8266 over uart.

I had seen the examples - secure_bootloader_dfu and iot example but still not able to understand the example.

Any help or suggestion in this.

I have the list of steps, please let me know if you have performed all the steps. 

We can't review the code just based on "it doesn't work". 

You need to debug the bootloader to find the reason. 

What was the issue with the UART DFU master example ? Which error do you have ?

I downloaded the example DFUMaster_Uart example

1. Open the project file and try to build the code.

2. I get nrf_log_backend_serial.c - no such file or directory.

Have you put the project into SDK v14.2 \example\peripheral folder ? 

nrf_log_backend_serial.c is located at \components\libraries\experimental_log\src

I have only modified the KEIL project, not the SES or IAR or GCC.

Hi

It is in \example\ble_peripherals.

I am using SES for testing purpose first, then I will move to GCC for my project.

Still getting the error.

I am able to resolve that now I am issue with slip.h, no such file or directory
