HSB FPGA Flash

Use this skill when the user wants to flash (upgrade or downgrade) the FPGA firmware on an HSB board connected to a supported NVIDIA devkit.

This skill supports two board types:

1. HSB Lattice boards — standalone FPGA board with a Lattice CPNX100 FPGA
2. Leopard Imaging VB1940 — "all-in-one" camera with an integrated Lattice FPGA

CRITICAL SAFETY RULE: Never mix board-type commands. Using program_leopard_cpnx100 on a Lattice board or program_lattice_cpnx100 on a VB1940 can permanently brick the device. The skill must detect and confirm the board type before any flash operation, and refuse to proceed if the board type is ambiguous or mismatched.

This workflow has side effects (it permanently modifies FPGA firmware). Never run it automatically. Only run it when the user explicitly invokes it.

Usage warning: This skill flashes the FPGA with new firmware. Before invoking it, ask the user to make sure they have enough Claude Code usage/tokens to complete the workflow.

Before you start — required gates (do these first, in order)

Gate 1 — Read environment variables. Before doing anything else, check these variables and print their resolved values to the user:
