In this tutorial, we start a new STM32 Modbus TCP series and configure the Ethernet peripheral, LWIP stack, and MPU using STM32CubeMX. We use the Nucleo H755 board with a static IP address and create a basic TCP server listening on the standard Modbus TCP port 502.

In this tutorial, we configure the STM32 USB peripheral in CDC (Communication Device Class) mode using STM32CubeMX and STM32CubeIDE. We transmit data from the STM32 to the PC, receive commands through the Virtual COM Port, and use those commands to control an LED. We also redirect printf over USB CDC so that the STM32 can use USB as a debug console. Along the way, we look at USB clock configuration, CDC receive handling, buffer management, and an important difference in USB reconnect behavior between the STM32F446 and Blue Pill boards.

In this tutorial, we continue the STM32 OTA bootloader series and implement a WiFi-based firmware update system. The ESP8266 connects to a WiFi network, establishes a TCP connection to the OTA server, downloads the firmware in chunks, and transfers the data to the STM32 over UART. The firmware is stored in W25Q external Flash before the update begins. After the firmware download is complete, the application sets the OTA flag and resets the MCU. The bootloader reads the OTA image from external Flash, validates the firmware, programs it into the internal application region, and finally jumps to the updated application. This approach is especially useful for STM32 devices with limited internal Flash memory.

In this tutorial, we continue the STM32 OTA bootloader series and implement a TCP-based firmware update using the W5500 Ethernet module. The STM32 works as a TCP client, connects to a server, requests the OTA firmware, receives it in chunks, and stores the complete OTA image in a dedicated Flash region. The application then sets the OTA flag and resets the MCU. After reset, the bootloader reads the OTA image from Flash, validates the firmware, programs it into the application region, and jumps to the updated application. We also configure the Flash layout, implement the TCP client and OTA stream, create a Python TCP server, and test the complete Ethernet OTA update process.

In this tutorial, we continue the STM32 custom bootloader series and extend the application validation with size and CRC32 checks. We add the application size and CRC to the application header, generate a CRC-ready binary without the header, and use a Python script to calculate the application size and CRC value. The bootloader checks the magic number, reset handler, application size, and calculated CRC before allowing the jump to the application. We also test both valid and corrupted firmware images, showing how the bootloader detects a CRC mismatch, reports the error through UART, and blocks the application from running.

In this tutorial, we continue the STM32 custom bootloader series and implement an OTA FLAG mechanism using the application header. The application sets the OTA flag in Flash and resets the MCU, allowing the bootloader to detect the request after reset and decide whether to start the OTA process or continue with normal application validation. The bootloader reads the OTA flag, clears it after detection to prevent repeated OTA requests, and then enters the OTA update flow. Since the actual firmware flashing is implemented in the next part, we use an external button to simulate the OTA request and a blinking LED to represent the OTA flashing state.
