ESP-IDF Monitor

ESP-IDF Monitor makes the following changes regarding baud-rate:

  • ESP-IDF monitor now uses the custom console baud-rate (CONFIG_ESP_CONSOLE_UART_BAUDRATE) by default instead of 115200.

  • Setting a custom baud from menuconfig is no longer supported.

  • A custom baud-rate can be specified from command line with the idf.py monitor -b <baud> command or through setting environment variables.

  • Please note that the baud-rate argument has been renamed from -B to -b in order to be consistent with the global baud-rate idf.py -b <baud>. Run idf.py monitor --help for more information.

Deprecated Commands

idf.py sub-commands and cmake target names have been unified to use hyphens (-) instead of underscores (_). Using a deprecated sub-command or target name will produce a warning. Users are advised to migrate to using the new sub-commands and target names. The following changes have been made:

Esptool

The CONFIG_ESPTOOLPY_FLASHSIZE_DETECT option has been renamed to CONFIG_ESPTOOLPY_HEADER_FLASHSIZE_UPDATE and has been disabled by default. New and existing projects migrated to ESP-IDF v5.0 have to set CONFIG_ESPTOOLPY_FLASHSIZE. If this is not possible due to an unknown flash size at build time, then CONFIG_ESPTOOLPY_HEADER_FLASHSIZE_UPDATE can be enabled. However, once enabled, to keep the digest valid, an SHA256 digest is no longer appended to the image when updating the binary header with the flash size during flashing.

Windows Environment

The Msys/Mingw-based Windows environment support got deprecated in ESP-IDF v4.0 and was entirely removed in v5.0. Please use ESP-IDF Tools Installer to set up a compatible environment. The options include Windows Command Line, Power Shell and the graphical user interface based on Eclipse IDE. In addition, a VS Code-based environment can be set up with the supported plugin: https://github.com/espressif/vscode-esp-idf-extension.
