Struct opentitanlib::transport::hyperdebug::dfu::HyperdebugDfu

pub struct HyperdebugDfu { /* private fields */ }

This transport is to be used if a Nucleo board is already in DFU bootloader mode at the time of the opentitantool invocation (and presenting itself with STMs VID:DID, rather than Google’s).

Implementations

impl HyperdebugDfu

pub fn open( usb_vid: Option<u16>, usb_pid: Option<u16>, usb_serial: Option<&str> ) -> Result<Self>

Establish connection with a particular Nucleo-L552ZE board possibly already in DFU bootloader mode.

Trait Implementations

impl Transport for HyperdebugDfu

The device does not support any part of the Transport trait, except the UpdateFirmware action.

fn capabilities(&self) -> Result<Capabilities>

Returns a Capabilities object to check the capabilities of this transport object.

fn dispatch(&self, action: &dyn Any) -> Result<Option<Box<dyn Annotate>>>

Invoke non-standard functionality of some Transport implementations.

fn apply_default_configuration(&self) -> Result<()>

Resets the transport to power-on condition. That is, pin/uart/spi configuration reverts to default, ongoing operations are cancelled, etc.

fn jtag(&self, _opts: &JtagParams) -> Result<Box<dyn JtagChain + '_>>

Returns a JtagChain implementation.

fn spi(&self, _instance: &str) -> Result<Rc<dyn Target>>

Returns a SPI Target implementation.

fn i2c(&self, _instance: &str) -> Result<Rc<dyn Bus>>

Returns a I2C Bus implementation.

fn uart(&self, _instance: &str) -> Result<Rc<dyn Uart>>

Returns a Uart implementation.

fn gpio_pin(&self, _instance: &str) -> Result<Rc<dyn GpioPin>>

Returns a GpioPin implementation.

fn gpio_monitoring(&self) -> Result<Rc<dyn GpioMonitoring>>

Returns a GpioMonitoring implementation, for logic analyzer functionality.

fn gpio_bitbanging(&self) -> Result<Rc<dyn GpioBitbanging>>

Returns a GpioBitbanging implementation, for timed and synchronized manipulation of multiple GPIO pins.

fn emulator(&self) -> Result<Rc<dyn Emulator>>

Returns a Emulator implementation.

fn proxy_ops(&self) -> Result<Rc<dyn ProxyOps>>

Methods available only on Proxy implementation.

fn maintain_connection(&self) -> Result<Rc<dyn MaintainConnection>>

As long as the returned MaintainConnection object is kept by the caller, this driver may assume that no other opentitantool processes attempt to access the same debugger device. This allows for optimzations such as keeping USB handles open across function invocations.

fn nonblocking_help(&self) -> Result<Rc<dyn NonblockingHelp>>

Before nonblocking operations can be used on Uart or other traits, this NonblockingHelp object must be invoked, in order to get the Transport implementation a chance to register its internal event sources with the main event loop.
