Struct probe_rs::architecture::arm::MemoryApInformation

pub struct MemoryApInformation {
    pub address: ApAddress,
    pub supports_only_32bit_data_size: bool,
    pub debug_base_address: u64,
    pub supports_hnonsec: bool,

    pub device_enabled: bool,
}

Information about a memory access port. Can be used for target discovery. Useful for detecting supported memory access of a target.

Fields

address: ApAddress

Zero-based port number of the access port. This is used in the debug port to select an AP.

supports_only_32bit_data_size: bool

Some Memory APs only support 32 bit wide access to data, while others also support other widths. Based on this, 8 bit data access can either be performed directly, or has to be done as a 32 bit access.

debug_base_address: u64

The Debug Base Address points to either the start of a set of debug register, or a ROM table which describes the connected debug components.

See chapter C2.6, ARM Debug Interface Architecture Specification.

supports_hnonsec: bool

Indicates if the HNONSEC bit in the CSW register is supported. See section E1.5.1, ARM Debug Interface Architecture Specification.

If HNONSEC is not supported, bit 30 in the CSW register has to be set to 1 at all times.

has_large_address_extension: bool

This AP has the large address extension present, supporting 64-bit addresses

has_large_data_extension: bool

This AP has the large data extension present, supporting 64-bit data access

device_enabled: bool

Memory transactions can be issued through this AP. If this bit is not set, no transactions can be issued.
