 # 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)
