D1S == F133 == C906

selection

F133 is essentially a rebranded D1s, also known as V851s, targeting AI camera and audio/video applications.

Both have 64-bit RISC-V cores (C906) and basic NPU, but F133/V851s is bundled with camera-optimized SDKs, especially for face recognition and object detection tasks.

If you're building a general-purpose Linux-based RISC-V board: D1s is the term used.

If you're building a smart camera or want Allwinner's AI SDKs: F133/V851s is preferred.

Warning: no 'soc_sram_info' data for your SoC (id=1859)
USB device 002:003   Allwinner 0x1859

The tool (e.g. sunxi-fel) does not recognize the SoC with ID 0x1859.
It lacks SRAM layout data (soc_sram_info) for this SoC.
Likely causes:
- Using a new or uncommon Allwinner SoC (e.g., F133, V853).
- Using an outdated version of the tool.
