Modes by switching between an input and output. Most adapters will have to emulate open-drain or open-source drive The output drive mode can be set to push-pull, open-drain or The configuration options enable signals to be defined as active-high orĪctive-low. Some adapters require that the GPIO chip number is set in addition to the GPIO - swdio_dir: optional swdio buffer control signal.When external configuration (such as jumpering) changes whatĬonfig Command: adapter gpio ]ĭefine the GPIO mapping that the adapter will use.

More additional commands to further identify or configure the adapter. Depending on the type of adapter, you may need to use one or The adapter driver command tells OpenOCD what type of debug adapter you are Most adapters need a bit more configuration than that.
