You will use a command‑line tool like dfu-util or the more common STM32CubeProgrammer (CLI version). For simplicity, use dfu-util:
dfu-util -a 0 -s 0x08000000:leave -D lighthouse-tx-htc-2-0-calibration-rescue-244.bin
If using STM32_FlashLoader.exe (older tool):
STM32_FlashLoader.exe -c --pn 1 --br 115200 -ow --fn lighthouse-tx-htc-2-0-calibration-rescue-244.bin -v --ep
Expected output:
Elias was working in a motion-capture studio in Austin, Texas (hence the tx in the filename, a signature he left in his code). They were rigging a professional athlete for a AAA video game. The studio had just spent thousands upgrading to the new 2.0 trackers, but the studio space was still equipped with the older, reliable V1 base stations. lighthouse-tx-htc-2-0-calibration-rescue-244.bin
Theoretically, 2.0 trackers were backward compatible. Theoretically.
At 2:00 PM, the lead animator stormed into the server room. "Elias, we’re dead in the water. The rig is spasming. The skeleton is dislocating. It looks like a glitch in the matrix out there."
Elias ran the diagnostics. The handshakes were failing. The sync pulse from the base stations wasn't being interpreted correctly by the new firmware on the trackers. The trackers were "blind"—they couldn't calibrate their position in the room because they didn't understand the timing signal from the base stations. You will use a command‑line tool like dfu-util
(Procedure depends on bootloader; examples for fastboot and dfu.)
Fastboot example:
DFU or vendor tool: use vendor utility to read partition into host file. Or use JTAG/UART to read eMMC. If using STM32_FlashLoader
Store backups securely.
Device / file: lighthouse-tx-htc-2-0-calibration-rescue-244.bin
Purpose: Recover and restore correct calibration data and firmware on Lighthouse TX (HTC 2.0) after corrupted or missing calibration partition; produce a validated, repeatable rescue procedure.
