IDF Monitor

IDF Monitor makes the following changes regarding baud-rate:

  • IDF monitor now uses the custom console baud-rate (:ref:`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:

Deprecated Sub-command and Target Names
Old Name New Name
efuse_common_table efuse-common-table
efuse_custom_table efuse-custom-table
erase_flash erase-flash
partition_table partition-table
partition_table-flash partition-table-flash
post_debug post-debug
show_efuse_table show-efuse-table
erase_otadata erase-otadata
read_otadata read-otadata

Esptool

The CONFIG_ESPTOOLPY_FLASHSIZE_DETECT option has been renamed to :ref:`CONFIG_ESPTOOLPY_HEADER_FLASHSIZE_UPDATE` and has been disabled by default. New and existing projects migrated to ESP-IDF v5.0 will have to set :ref:`CONFIG_ESPTOOLPY_FLASHSIZE`. If this is not possible due to an unknown flash size at build time, then :ref:`CONFIG_ESPTOOLPY_HEADER_FLASHSIZE_UPDATE` can be enabled. However, once enabled, to keep the digest valid, a SHA256 digest will no longer be 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 :ref:`get-started-windows-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.
