Compose a UDS bootloader workflow with BMCLI

A UDS bootloader demonstrates the deeper capability: scripts and glue languages compose focused BMCLI operations into complex, stable system tools.

Before programming, verify ECU identity, artifact checksum, address map, preconditions, power, session, security level, recovery path, and authorization. Query installed UDS Help rather than guessing OEM parameters.

Terminal window
bmcli help uds present start --format=json
bmcli help uds unlock --format=json
bmcli help uds download --format=json

A typical flow identifies the ECU, enters the correct session, keeps TesterPresent alive, unlocks security through an approved library, prepares memory, transfers segments, verifies the image, resets, and reads the resulting version. uds download implements the transfer phase, not every OEM precondition or post-programming check.

The same composition model supports diagnostic inspection, end-of-line checks, parameter programming, regression testing, and remote service tools. BMCLI supplies stable engineering primitives; Shell, Python, CI, or AI supplies project logic.
