snagboot 2.6

Generic recovery and reflashing tool for embedded platforms

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.

Snagboot currently supports the following families of System-On-Chips (SoCs):

• Allwinner sunxi A10, A10S, A13, A20, A23, A31, A33, A63, A64, A80, A83T, AF1C100S, H2+, R8, R16, R40, R329, R528, T113-S3, V3S, V5S, V536, V831, V853
• STMicroelectronics STM32MP1 and STM32MP2
• Microchip SAMA5
• NXP i.MX6, i.MX7, i.MX8, i.MX91, i.MX93
• Texas Instruments AM335x, AM62x, AM62Lx, AM64x, AM654x
• Xilinx/AMD Zynq UltraScale+ MPSoC
• Intel Keembay
• Broadcom BCM2711 and BCM2712, used in Raspberry Pi 4 & 5
• AMLogic series: G12A (eg S905D2), G12B (eg A311D), SM1 (eg S905D3) and series: GXL (eg S905D), GXM (eg S912), GXBB (eg S905), AXG (eg A113D)
• Renesas RZ/N1 series
