+## v1.4
+
+Turbo mode (gotta go fast)! The app now supports flashing as fast as possible (921600 baud with built-in retries). In my testing, this sped up a 1:37min flash to 23 seconds. Now we can't go back to the slow way!
+
+
 ## v1.3
 
 No functionality changes. Fixed the build by removing deprecated API calls that weren't needed.

-# esp-serial-flasher
-
-`esp-serial-flasher` is a portable C library for flashing or loading apps to RAM of Espressif SoCs from other host microcontrollers.
-
-## Using the library
-Espressif SoCs are normally programmed via serial interface (UART). The port layer for the given host microcontroller has to be implemented if not available. Details can be found in section below.
-
-Supported **host** microcontrollers:
-
-- STM32
-- Raspberry Pi SBC
-- ESP32
-- Any MCU running Zephyr OS
-
-Supported **target** microcontrollers:
-
-- ESP32
-- ESP8266
-- ESP32-S2
-- ESP32-S3
-- ESP32-C3
-- ESP32-C2
-- ESP32-H2
-
-Supported hardware interfaces:
-- UART
-- SPI (only for RAM download, experimental)
-
-For example usage check the `examples` directory.
-
-## Supporting a new host target
-
-In order to support a new target, following functions have to be implemented by user:
-
-- `loader_port_read()`
-- `loader_port_write()`
-- `loader_port_enter_bootloader()`
-- `loader_port_delay_ms()`
-- `loader_port_start_timer()`
-- `loader_port_remaining_time()`
-
-For the SPI interface ports
-- `loader_port_spi_set_cs()`
-needs to be implemented as well.
-
-The following functions are part of the [io.h](include/io.h) header for convenience, however, the user does not have to strictly follow function signatures, as there are not called directly from library.
-
-- `loader_port_change_transmission_rate()`
-- `loader_port_reset_target()`
-- `loader_port_debug_print()`
-
-Prototypes of all functions mentioned above can be found in [io.h](include/io.h).
-
-## Configuration
-
-These are the configuration toggles available to the user:
-
-* `SERIAL_FLASHER_INTERFACE_UART/SERIAL_FLASHER_INTERFACE_SPI`
-
-This defines the hardware interface to use. SPI interface only supports RAM download mode and is in experimental stage and can undergo changes.
-
-Default: SERIAL_FLASHER_INTERFACE_UART
-
-* `MD5_ENABLED`
-
-If enabled, `esp-serial-flasher` is capable of verifying flash integrity after writing to flash.
-
-Default: Enabled
-> Warning: As ROM bootloader of the ESP8266 does not support MD5_CHECK, this option has to be disabled!
-
-* `SERIAL_FLASHER_RESET_HOLD_TIME_MS`
-
-This is the time for which the reset pin is asserted when doing a hard reset in milliseconds.
-
-Default: 100
-
-* `SERIAL_FLASHER_BOOT_HOLD_TIME_MS`
-
-This is the time for which the boot pin is asserted when doing a hard reset in milliseconds.
-
-Default: 50
-
-Configuration can be passed to `cmake` via command line:
-
-```
-cmake -DMD5_ENABLED=1 .. && cmake --build .
-```
-
-### STM32 support
-
-The STM32 port makes use of STM32 HAL libraries, and these do not come with CMake support. In order to compile the project, `stm32-cmake` (a `CMake` support package) has to be pulled as submodule.
-
-```
-git clone --recursive https://github.com/espressif/esp-serial-flasher.git
-```
-
-If you have cloned this repository without the `--recursive` flag, you can initialize the submodule using the following command:
-
-```
-git submodule update --init
-```
-
-In addition to configuration parameters mentioned above, following definitions has to be set:
-
-- TOOLCHAIN_PREFIX: path to arm toolchain (i.e /home/user/gcc-arm-none-eabi-9-2019-q4-major)
-- STM32Cube_DIR: path to STM32 Cube libraries (i.e /home/user/STM32Cube/Repository/STM32Cube_FW_F4_V1.25.0)
-- STM32_CHIP: name of STM32 for which project should be compiled (i.e STM32F407VG)
-- PORT: STM32
-
-This can be achieved by passing definitions to the command line, such as:
-
-```
-cmake -DTOOLCHAIN_PREFIX="/path_to_toolchain" -DSTM32Cube_DIR="path_to_stm32Cube" -DSTM32_CHIP="STM32F407VG" -DPORT="STM32" .. && cmake --build .
-```
-
-Alternatively, those variables can be set in the top level `cmake` directory:
-
-```
-set(TOOLCHAIN_PREFIX    path_to_toolchain)
-set(STM32Cube_DIR       path_to_stm32_HAL)
-set(STM32_CHIP          STM32F407VG)
-set(PORT                STM32)
-```
-
-### Zephyr support
-
-The Zephyr port is ready to be integrated into Zephyr apps as a Zephyr module. In the manifest file (west.yml), add:
-
-```
-    - name: esp-flasher
-      url: https://github.com/espressif/esp-serial-flasher
-      revision: master
-      path: modules/lib/esp_flasher
-```
-
-And add
-
-```
-CONFIG_ESP_SERIAL_FLASHER=y
-CONFIG_CONSOLE_GETCHAR=y
-CONFIG_SERIAL_FLASHER_MD5_ENABLED=y
-```
-
-to the project configuration `prj.conf`.
-
-For the C/C++ source code, the example code provided in `examples/zephyr_example` can be used as a starting point.
-
-## Licence
-
-Code is distributed under Apache 2.0 license.
-
-## Known limitations
-
-Size of new binary image has to be known before flashing.

-# Flash multiple partitions example
-
-## Overview
-
-Example demonstrates how to flash ESP32/ESP32-S2/ESP8266 from another (host) MCU using esp_serial_flash component API. In this case, ESP32 is also used as host MCU. Binaries to be flashed from host MCU to another Espressif SoC can be found in `binaries` folder and are converted into C-array during build process.
-
-Following steps are performed in order to re-program target's memory:
-
-1. Filesystem is initialized and mounted.
-2. UART1 through which new binary will be transfered is initialized.
-3. Host puts slave device into boot mode tries to connect by calling `esp_loader_connect()`.
-4. Binary file is opened and its size is acquired, as it has to be known before flashing.
-5. Then `esp_loader_flash_start()` is called to enter flashing mode and erase amount of memory to be flashed.
-6. `esp_loader_flash_write()` function is called repeatedly until the whole binary image is transfered.
-
-Note: In addition, to steps mentioned above, `esp_loader_change_transmission_rate`  is called after connection is established in order to increase flashing speed. This does not apply for ESP8266, as its bootloader does not support this command. However, ESP8266 is capable of detecting baud rate during connection phase, and can be changed before calling `esp_loader_connect`, if necessary.
-
-## SPI pin initialization
-
-In majority of cases `ESP_LOADER_CONNECT_DEFAULT` helper macro is used in order to initialize `loader_connect_args_t` data structure passed to `esp_loader_connect`. Helper macro sets `spi_pin_config` field of the data structure to zero, thus, default SPI pins are used to connect to FLASH memory. In special cases, such as custom design in which FLASH is connected to different pins, `spi_pin_config` field has to be set accordingly. For more detailed information refer to [serial protocol](https://docs.espressif.com/projects/esptool/en/latest/esp32s3/advanced-topics/serial-protocol.html).
-
-## Hardware Required
-
-* Two development boards with ESP32 SoC (e.g., ESP32-DevKitC, ESP-WROVER-KIT, etc.).
-* One or two USB cables for power supply and programming.
-
-## Hardware connection
-
-Table below shows connection between two ESP32 devices.
-
-| ESP32 (host) | ESP32 (slave) |
-|:------------:|:-------------:|
-|    IO26      |      IO0      |
-|    IO25      |     RESET     |
-|    IO4       |      RX0      |
-|    IO5       |      TX0      |
-
-Note: interconnection is the same for all three targets (slaves). 
-
-## Build and flash
-
-To run the example, type the following command:
-
-```CMake
-idf.py -p PORT flash monitor
-```
-
-(To exit the serial monitor, type ``Ctrl-]``.)
-
-See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
-
-## Configuration
-
-For details about available configuration option, please refer to top level [README.md](../../README.md). 
-Compile definitions can be specified on command line when running `idf.py`, for example:
-
-```
-idf.py build -DMD5_ENABLED=1
-```
-Binaries to be flashed are placed in separate folder (binaries.c) for each possible target and converted to C-array. Without explicitly enabling MD5 check, flash integrity verification is disabled by default.
-
-## Example output

-Here is the example's console output:

-# Example of loading the program into RAM through SPI
-
-## Overview
-
-This example demonstrates how to upload an app to RAM of an Espressif MCU with SPI download support from another (host) MCU using the `esp_serial_flash` component API. In this case, another Espressif MCU is used as the host. Binaries to be uploaded to RAM from host MCU to the target MCU can be found in `binaries/RAM_APP` folder and are converted into C-array during build process.
-
-Following steps are performed in order to re-program the target's memory:
-
-1. SPI2 through which the binary will be transfered is initialized.
-2. Host puts slave device into SPI download mode tries to connect by calling `esp_loader_connect()`.
-3. Then `esp_loader_mem_start()` is called for each segment in RAM.
-4. `esp_loader_flash_write()` function is called repeatedly for every segment until the whole binary image is transfered.
-5. `esp_loader_mem_finish()` is called with the binary entrypoint, telling the chip to start the uploaded program.
-6. UART2 is initialized for the connection to the target
-7. Target output is continually read and printed
-
-## Hardware Required
-
-* Two development boards, one with any Espressif MCU (e.g., ESP32-DevKitC, ESP-WROVER-KIT, etc.) and one with an Espressif MCU with SPI download support. Here is a short list of supported MCUs:
-1. ESP32-C3
-2. ESP32-C2
-3. ESP32-S3
-4. ESP32-S2
-5. ESP32-H2
-* One or two USB cables for power supply and programming.
-
-## Hardware connection
-
-Table below shows connection between two Espressif MCUs.
-
-| Host         | Slave         |
-|    IO_5      |    RESET      |
-|    IO_12     |    CLK        |
-|    IO_10     |    CS         |
-|    IO_13     |    MISO       |
-|    IO_11     |    MOSI       |
-|    IO_14     |    QUADWP     |
-|    IO_9      |    QUADHD     |
-|    IO_13     |    STRAP_B0   |
-|    IO_2      |    STRAP_B1   |
-|    IO_3      |    STRAP_B2   |
-|    IO_4      |    STRAP_B3   |
-|    IO_6      |    UART0_RX   |
-|    IO_7      |    UART0_TX   |
-
-> Note 1: Strapping bit pins are documented in the TRM for each respective chip
-
-> Note 2: For achieving highest speeds, check which pins go through the IO MUX bypassing the GPIO matrix and use those. Pins chosen here are IO MUX pins for ESP32S3 and ESP32S2 chips.
-
-## Build and flash
-
-To run the example, type the following command:
-
-```CMake
-idf.py -p PORT flash monitor
-```
-
-(To exit the serial monitor, type ``Ctrl-]``.)
-
-See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
-
-## Example output
-
-Here is the example's console output:
-
-```

-# Raspberry Pi example
-
-## Overview
-
-Example demonstrates how to flash ESP32 from Raspberry Pi 4 (Model B) using esp_serial_flash component API. AT command firmware to be flashed from Raspberry Pi to ESP32 can be found in `binaries`. USART0 is dedicated for communication with ESP32.
-
-Following steps are performed in order to re-program target's memory:
-
-1. Peripherals are initialized.
-2. Host puts slave device into boot mode tries to connect by calling `esp_loader_connect()`.
-3. Then `esp_loader_flash_start()` is called to enter flashing mode and erase amount of memory to be flashed.
-4. `esp_loader_flash_write()` function is called repeatedly until the whole binary image is transfered.
-5. At the end, `loader_port_reset_target()` is called to restart ESP32 and execute updated firmware.
-
-Note: In addition, to steps mentioned above, `esp_loader_change_transmission_rate`  is called after connection is established in order to increase flashing speed. Bootloader is also capable of detecting baud rate during connection phase, and can be changed before calling `esp_loader_connect`. However, it is recommended to start at lower speed and then use dedicated command to increase baud rate. This does not apply for ESP8266, as its bootloader does not support this command, therefore, baud rate can only be changed before connection phase in this case.
-
-## Hardware Required
-
-* Raspberry Pi 4 Model B. 
-* A development board with ESP32 SoC (e.g. ESP-WROVER-KIT, ESP32-DevKitC, etc.).
-* USB cable in case ESP32 board is powered from USB. ESP32 can be powered by Raspberry Pi as well.
-
-## Hardware connection
-
-Table below shows connection between Raspberry Pi and ESP32.
-
-| Raspberry Pi (host) |    ESP32 (slave)    |
-|:-------------------:|:-------------------:|
-|        GPIO3        |         IO0         |
-|        GPIO2        |         RST         |
-|        GPIO14       |         RX0         |
-|        GPIO15       |         TX0         |
-|         GND         |         GND         |
-
-Optionally, UART-to-USB bridge can be connected to PD5(RX) and PD6(TX) for debug purposes.
-
-## Installation
-
-### GPIO library
-Raspberry Pi makes use of [pigpio](http://abyz.me.uk/rpi/pigpio/) library in order to simplify controlling GPIO pins. Some distributions of 'Raspberry Pi OS' may come with `pigpio` already installed. Presence of the library in the system can checked by running command:
-```
-pigpiod -v
-```
-
-If not present, run following commands to install the library. 
-```
-sudo apt-get update
-sudo apt-get install pigpio
-```
-
-### Enable UART
-On Raspberry Pi 4, primary UART (UART0) is connected to the On-board Bluetooth module by default.
-In order to enable serial communication on this UART, run following command in terminal:
-```
-sudo raspi-config
-```
-
-* Navigate to **Interfacing Options -> Serial**.
-* Then it will ask for login shell to be accessible over Serial, select **No**.
-* After that, it will ask for enabling Hardware Serial port, select **Yes**.
-* Reboot the Raspberry Pi.
-
-## Build and run
-
-To compile the example:
-
-Create and navigate to `build` directory:

-# STM32 example
-
-## Overview
-
-Example demonstrates how to flash ESP32 from another STM32 (host MCU) using esp_serial_flash component API. STM32F4-Discovery board is used in this example, as STM32F407VG has FLASH memory large enough to fit the whole hello-world example of ESP32. Binaries to be flashed from host MCU to ESP32 can be found in `binaries` directory and converted into C-arrays during build process. USART1 is dedicated for communication with ESP32, whereas, USART2 can be used for debug purposes by attaching UART-to-USB bridge.
-
-Following steps are performed in order to re-program target's memory:
-
-1. Peripherals are initialized.
-2. Host puts slave device into boot mode tries to connect by calling `esp_loader_connect()`.
-3. Then `esp_loader_flash_start()` is called to enter flashing mode and erase amount of memory to be flashed.
-4. `esp_loader_flash_write()` function is called repeatedly until the whole binary image is transfered.
-
-Note: In addition, to steps mentioned above, `esp_loader_change_transmission_rate`  is called after connection is established in order to increase flashing speed. Bootloader is also capable of detecting baud rate during connection phase, and can be changed before calling `esp_loader_connect`. However, it is recommended to start at lower speed and then use dedicated command to increase baud rate. This does not apply for ESP8266, as its bootloader does not support this command, therefore, baud rate can only be changed before connection phase in this case.
-
-## Hardware Required
-
-* STM32F4-Discovery board. 
-* A development board with ESP32 SoC (e.g. ESP-WROVER-KIT, ESP32-DevKitC, etc.).
-* One or two USB cables for power supply and programming.
-
-## Hardware connection
-
-Table below shows connection between STM32 and ESP32.
-
-| STM32 (host) | ESP32 (slave) |
-|:------------:|:-------------:|
-|    PB5       |      IO0      |
-|    PB4       |      RST      |
-|    PB6       |      RX0      |
-|    PB7       |      TX0      |
-
-Optionally, UART-to-USB bridge can be connected to PD5(RX) and PD6(TX) for debug purposes.
-
-## Build and flash
-
-To compile the example:
-
-Create and navigate to `build` directory:
-```
-mkdir build && cd build
-```
-Run cmake (with appropriate parameters) and build: 
-```
-cmake -DTOOLCHAIN_PREFIX="/path_to_toolchain" -DSTM32Cube_DIR="path_to_stm32Cube" -DSTM32_CHIP="STM32F407VG" -DPORT="STM32" .. && cmake --build .
-```
-
-Binaries to be flashed are placed in separate folder (binaries.c) for each possible target and converted to C-array. Without explicitly enabling MD5 check, flash integrity verification is disabled by default.
-
-For more details regarding to esp_serial_flasher configuration and STM32 support, please refer to top level [README.md](../../README.md).
-
-Note: CMake 3.13 or later is required.
-
-## STM32CubeMx configuration
-
-Following configuration was used to generate STM32 `cmake` based project:
-* Project tab: Toolchain/IDE - Other toolchain (GPDSC)
-* Code Generator tab: Add necessary files as reference in the toolchain project configuration file

-## Overview
-
-This sample code demonstrates how to flash ESP32/ESP32-S2/ESP8266 from another (host) MCU using
-esp_serial_flash component API. In this case, ESP32 is also used as host MCU.
-Binaries to be flashed from host MCU to another Espressif SoC can be found in `binaries` folder
-and are converted into C-array during build process.
-
-Following steps are performed in order to re-program target's memory:
-
-1. Peripherals are initialized (GPIO for BOOT and EN pins and UART).
-2. UART1 (can be changed) through which new binary will be transfered is initialized.
-3. Host puts slave device into boot mode tries to connect by calling `esp_loader_connect()`.
-4. Binary file is opened and its size is acquired, as it has to be known before flashing.
-5. Then `esp_loader_flash_start()` is called to enter flashing mode and erase amount of memory to be flashed.
-6. `esp_loader_flash_write()` function is called repeatedly until the whole binary image is transfered.
-
-Note: In addition, to steps mentioned above, `esp_loader_change_transmission_rate`  is called after connection
-is established in order to increase flashing speed. This does not apply for ESP8266, as its bootloader
-does not support this command. However, ESP8266 is capable of detecting baud rate during connection
-phase, and can be changed before calling `esp_loader_connect`, if necessary.
-
-## Hardware Required
-
-* Two development boards with ESP32 SoC (e.g., ESP32-DevKitC, ESP-WROVER-KIT, etc.).
-* One or two USB cables for power supply and programming.
-
-## Hardware connection
-
-Table below shows connection between two ESP32 devices.
-
-| ESP32 (host) | ESP32 (slave) |
-|:------------:|:-------------:|
-|    IO4       |      IO0      |
-|    IO2       |     RESET     |
-|    IO9       |      TX0      |
-|    IO10      |      RX0      |
-
-Note: interconnection is the same for all three targets (slaves).
-
-## Build and flash
-
-To run the example, type the following command:
-
-```c
-west build -p -b esp32
-west flash
-west espressif monitor
-```
-
-(To exit the serial monitor, type ``ctrl-c``.)
-
-For more information, check [Zephyr's Getting Started](https://docs.zephyrproject.org/latest/develop/getting_started/index.html)
-
-## Configuration
-
-For details about available configuration option, please refer to top level [README.md](../../README.md).
-Compile definitions can be specified in `prj.conf` file.
-
-Binaries to be flashed are placed in separate folder (binaries.c) for each possible target and converted to C-array. Without explicitly enabling MD5 check, flash integrity verification is disabled by default.
-
-## Example output
-
-Here is the example's console output:
-
-```
