# at32flash
Flash program for AT32 using the AT serial bootloader, based on [stm32flash](https://github.com/stm32duino/stm32flash).
at32flash 0.1 is a release with these highlights:
**at32flash 0.1** is a release with these highlights:
- Support for **AT32F435** beside the STM32 MCUs
## Features
UART and I2C transports supported
device identification
write to flash/ram
read from flash/ram
auto-detect Intel HEX or raw binary input format with option to force binary
flash from binary file
save flash to binary file
verify & retry up to N times on failed writes
start execution at specified address
software reset the device when finished if -R is specified
resume already initialized connection (for when reset fails, UART only)
GPIO signalling to enter bootloader mode (hardware dependent)

(internal notes)
- Get the latest version of Mingw-w64 via [MSYS2](https://www.msys2.org/), which provides up-to-date native builds of GCC, Mingw-w64, and other helpful C++ tools and libraries. You can download the latest installer from the MSYS2 page or use this [link to the installer](https://github.com/msys2/msys2-installer/releases/download/2022-01-18/msys2-x86_64-20220118.exe).
- Follow the Installation instructions on the MSYS2 website to install Mingw-w64. Commands to be lunched in MinGW:
```
pacman -Syu
pacman -Su
pacman -S --needed base-devel mingw-w64-x86_64-toolchain
pacman -S make
pacman -S mingw-w64-x86_64-gcc
```
- In MinGW shell, enter the project folder and lunch `make`
- (optional) Add the path to your Mingw-w64 bin folder (ie. `C:\msys64\mingw64\bin`) to the Windows PATH environment variable.
