[dependabot]

Bumps esptool from 2.8 to 4.5.

Release notes

Sourced from esptool's releases.

Version 4.5

This release aims to fix most of the major issues with resetting into the download mode, flashing in the USB-Serial/JTAG mode, and working with large-capacity flash memory chips.

New Features

• Configuration file: Added the option to configure internal variables (such as timeouts and delays) and to implement a custom reset sequence (see the related documentation).
• Bootloader reset: Added a new reset strategy to make resetting into the download mode more reliable on MacOS and Linux systems (espressif/esptool#712).
• ESP32-S3: Added support for >32MB octal flash chips (espressif/esptool#795, espressif/esptool#745).
• ESP32-H2: Added full esptool and flasher stub support.
• ESP32-C6: Added full flasher stub support.
• flash_id: Print the flash memory chip type (quad vs. octal) if available (espressif/esptool#730).
• elf2image: Added --pad-to-size <size> option to specify a size to which the generated binary image must be aligned.
• write_flash: Added a security check to prevent bricking the device when flash encryption is active.
• Optimized to reduce the number of steps when a chip is being interrogated.

espsecure.py

• Added an external HSM signing interface.
• Added support for pre-calculated signatures.
• Added PKCS#8 identifier support (espressif/esptool#819).

Bug Fixes

• USB-Serial/JTAG: Fixed randomly failing transfers when writing/reading large binaries.
• ESP32-S3: Fixed crashing stub flasher when using in USB-Serial/JTAG mode (espressif/esptool#808)
• ESP32: Recalculate the crystal clock to compensate for the chips baud rate setting as a workaround to avoid ESP32 CK_8M frequency drift.
• ESP32-S3: Fixed v0.0 chip being detected as vX.8.
• StopIteration: Fixed several possible errors when stub flasher is being uploaded and added better error messages for other cases (espressif/esptool#824).
• Fixed chip autodetection and operations in the secure download mode on ESP32-S2 and S3 (espressif/esptool#813).
• write_flash: Fixed the --erase-all option corrupting flash (espressif/esptool#805).
• write_flash: Fixed security checks when min_rev and max_rev_full are specified in the image.
• Fixed compatibility with bitstring>=4 package.
• Fixed compatibility with reedsolo when using Python 3.10 and Cython (espressif/esptool#711).

espefuse.py

• The serial port now gets closed when espefuse fails (espressif/esptool#803).

Miscellaneous Changes

• Refactored to make adding new targets easier, reduce code repetition, and comply with the Black 23.1 style.
• Added target tests for all of the newly supported chips.
• Updated the toolchains for stub flasher builds.

Thanks to @​256dpi, @​StevenMacias, @​fennecbutt, and others for contributing to this release!

Version 4.4

New Features

• flasher_stub: Increased read/write speeds over USB-JTAG/Serial or USB-OTG modes, making some operations nearly twice as fast.
