Snagboot

Snagboot intends to be an open-source and generic replacement to the vendor-specific, sometimes proprietary, tools used to recover and/or reflash embedded platforms. Examples of such tools include STM32CubeProgrammer, SAM-BA ISP, UUU, and sunxi-fel. Snagboot is made of three separate parts:

• snagrecover uses vendor-specific ROM code mechanisms to initialize external RAM and run U-Boot, without modifying any non-volatile memories.
• snagflash communicates with U-Boot to flash system images to non-volatile memories, using either DFU, UMS or Fastboot.
• snagfactory orchestrates and parallelizes factory flashing tasks efficiently on groups of devices.
