So, once the node is located in the field, the firmware update is a challenging problem because of the distance. Since power consumption is fairly low of this node, the battery life is up to 10 years. For example, there is a LoRaWAN end node in the field, and the distance from the Gateway to the end node can reach up to 15 km outdoor. We can change this scenario for WiFi… If the product has a feature to connect a wireless network, the firmware update process can be launched automatically in case there is an updated firmware on the server. Now the user can upload this file to the product via Bluetooth by using a GUI on a Desktop or a mobile application. bin format and forward the output file to the user. The second way is, again we can develop the firmware at the office and extract the code file into a predefined output file such as. Once the firmware has been upload to the product and delivered to the user in the field, it might be needed to update the current firmware because of some bugs or maybe there is a new feature, so what do we need to do? One way is we can develop the firmware at the office, and travel to the field with the updating tools (Laptop, programmer, etc.), and connect the USB cable to the product for updating. For example, in a project, a Bluetooth module might be used to transfer data and this current connection can be used to firmware update wirelessly at the same time. These are a type of gate where the MCU can talk to the external world. Finally, jumping to the application code from the bootloader is the last step.Īlright, let’s focus on the communication busses.

This received firmware is written into an allocated area of the Flash Memory. As the bootloader is triggered, a byte stream from the external world via communication busses such as UART, CAN, SPI, etc. Basically, it works when the MCU is powered up or restart state, or in some cases, it can be triggered by the software. Actually, a bootloader is a piece of code that manages the flow of the program inside the memory.

Let’s first figure out what is the purpose of a bootloader, and why it is so interesting. Therefore, I decided to find out how can I develop a bootloader where all system requirements can be defined according to my project’s demands. That bootloader was pretty advantageous and comfortable for updating firmware over the air, however, I felt a little bit restricted since I was dependent on the FlashLoaderDemonstrator and its configuration parameters. I previously mentioned the internal bootloader of STM32F407VGt6 in this link.
