Enum MultiCoreStrategy 

#[non_exhaustive]
pub enum MultiCoreStrategy {
    Error,
    AutoPark,
    Ignore(IgnoreMarker),
}

Available on crate feature unstable only.

Strategy for the other core during flash operations.

Stability

This API is marked as unstable and is only available when the unstable crate feature is enabled. This comes with no stability guarantees, and could be changed or removed at any time.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Error

Returns Error::OtherCoreRunning if the other core is running.

AutoPark

Available on crate feature rt only.

Posts an IPC function on the other core for the operation.

The function runs from RAM. The function masks interrupts on that core and waits until the operation finishes. The operation waits until that core enters the function. A core that does not take the IPC interrupt delays the operation.

If crate::system::CpuControl did not start the APP core, the CPU-control registers stall that core instead.

Ignore(IgnoreMarker)

Does not check or stop the other core.

Construct with Self::ignore.

Implementations

impl MultiCoreStrategy

pub const unsafe fn ignore() -> Self

Creates a strategy that does not check or stop the other core.

Safety

The other core must not fetch instructions or data from flash during any operation, including reads. Flash-backed caches are unavailable while an operation runs.

Stability

This API is marked as unstable and is only available when the unstable crate feature is enabled. This comes with no stability guarantees, and could be changed or removed at any time.
