# Flash BSP Image

## Purpose

Push a promoted `bsp_image` to a Jetson DUT by running the NVIDIA flashing toolchain (`flash.sh` or `l4t_initrd_flash.sh`) from the in-tree `Linux_for_Tegra/`. The DUT must be in RCM (recovery) mode at flash time. This is the **flash leg** of the BSP overlay deploy chain (`/jetson-promote-image` → `/jetson-flash-image`); see the BSP overlay workflow at `../../context/bsp-customization-workflow.md`.

**Design principle.** Four invariants govern this skill; each is fully explained in the Instructions step that owns it.

- Host-side flash variables (`<board>`, `<boot-dev>`, flow tool, per-board `.conf`, `boardctl`) are resolved from the active profile or the in-tree BSP.
- Artifact paths (`DTB_FILE`, `BPFDTB_FILE`, partition XML, BCTs, DRAM training) are resolved inside `flash.sh` / `l4t_initrd_flash.sh` at flash time from `board_sku` / `board_FAB` read off the DUT's EEPROM.
- The DUT's EEPROM is authoritative; the profile is an authoring-time prediction reconciled by the preflight cross-check. Empty EEPROM values are valid, not refusal triggers.
- The user explicitly confirms a printed *resolution* before flashing.

Out of scope: BSP customization (use the `/jetson-customize-*` skills), promoting the overlay tracker into `bsp_image` (use `/jetson-promote-image`), and producing a custom carrier's flash conf (use `/jetson-derive-carrier`).
