Devcontainer now grants libusb access to the FT2232H so iceprog (bitstream) and pyftdi (FT2232H EEPROM) run inside the container: - devcontainer.json: --privileged + /dev/bus/usb bind mount - Dockerfile: sudo (NOPASSWD for vscode; USB nodes are root-owned), libusb-1.0-0, libftdi1-2, pyftdi Add the flash-re-bba-rb skill documenting the procedure (bitstream via best swept seed, optional EEPROM string, troubleshooting, guardrails) and flash_ftdi_eeprom.py (pyftdi, backup-first, dry-run default) + ftdi_eeprom.conf value spec. Bring-up on the repaired V1 unit: bitstream flash VERIFY OK (iceprog build/seed4/top.bin, capture 58.36 MHz). EEPROM product string CANNOT be programmed on V1 — U7 is a 93LC46B (128 B), too small for the FT2232H, which needs a 93LC56B (256 B); the 128 B chip mirrors and the config write fails verify. This overturns the old REVIEW note "93LC46B = correct for FT2232H" (that only checked ORG, not size). Board still works blank -> ROM defaults; iceprog + UART unaffected. Documented in REVIEW.md + TODO.md (swap U7->93LC56B for V2); flash_ftdi_eeprom.py detects the mirroring and refuses the write. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
