Device

show all USB devices (no VID/PID filter)

Not connected. Default filter: any espp device (VID 0x1209); the vendor (0xFF) interface is discovered from the descriptors at runtime.

Firmware update

No file selected. Pick the app image (e.g. build/ota_example.bin) — NOT the merged / bootloader image.

After an OTA the new image boots pending verify: confirm it here (the app must not confirm itself) or it rolls back on the next reset.

Log

log raw frames

Speaks the espp ota component's vendor-interface stream protocol (frame: magic "OT" + flags + module + type + len + payload + CRC-32, 4096-byte max payload, one transaction in flight). After FINISH the device validates the image (SHA-256), sets the boot partition and restarts; with bootloader rollback enabled the new app must mark itself valid or the device rolls back.
