New since v2.0.1

ESP32-Specific Changes

elf2image: Pad flash-resident sections to 64KB alignment by using parts of RAM-resident sections, rather than zeroes. This reduces the size of a final IDF binary by almost 128KB in some cases.
elf2image: Append a SHA-256 hash of the binary image to the .bin file by default. This will be checked by the software bootloader in the IDF V3.0 release. Provides a much stronger consistency check than the previous 8-bit checksum. The image_info command will print & verify this hash if it is present.
espefuse.py: timeout now calculated in seconds not number of retries.

Documentation Changes

esptool.py version 2.0.1 is a minor bugfix release from v2.0.

New since v2.0:

(ESP32) Generating bootloader images for ESP32D2WD, or any ESP32 where the SPI pins are remapped via efuse, no longer accidentally enables GPIO0 as an output.
(ESP32) espsecure.py & espefuse.py: Dispay --help argument if run without command line arguments.

v2.0

582a069

Version 2.0

Latest stable release available from PyPi:
https://pypi.python.org/pypi/esptool/

This release:
https://pypi.python.org/pypi/esptool/2.0

esptool.py version 2.0 is a major release compared to v1.x. Most command line options are backwards compatible, but some default settings have changed.

New Features

Support added for ESP32 microcontrollers.
Compressed upload support (enabled by default) to reduce overhead of the serial connection.
Data written to flash is automatically read back and verified after writing.
New boot mode selection options --before and --after, to override the way esptool.py enters and exits bootloader mode, respectively. Details here.
New --flash_mode keep and --flash_freq keep default options mean that write_flash no longer modifies these settings in the image header by default.

ESP32-Only Features

--spi-connection argument allows overriding SPI flash pin configuration. Details here.
New espefuse.py program for working with efuses.
New espsecure.py program for working with chip security features.
esptool.py prints the ESP32 detailed chip model and silicon revision as part of console output.

Thanks to everyone who contributed to this release, and submitted bug reports during the long beta period!

esptool.py is now officially supported by Espressif Systems (software licensing & approach to development have not changed.)
verify_flash command now accepts optional --flash_mode and --flash_speed arguments, allowing verification of a ROM bootable image at offset 0.
Backport functional tests (test_esptool.py) from esptool v2.0
