Detailed Description

examples/ek_ra8d2/hw_validated/manual/tz_secure_only_usb_hs/inc/tz_secure_only_usb_hs_steps.h

ThreadX + USBX worker machinery for the secure-only USB-HS echo app.

Tag: [Ring 6 / APP] {World: S}

Companion sibling header for examples/ek_ra8d2/hw_validated/manual/tz_secure_only_usb_hs/src/main.c. The CDC-ACM activate/deactivate callbacks, the USBX bring-up step routines, the INTENB0 re-arm watchdog and the ThreadX tx_application_define kernel hook were factored out of main.c verbatim into tz_secure_only_usb_hs_steps.c, and the four USBX descriptor byte arrays into tz_secure_only_usb_hs_descriptors.c, to keep every translation unit under the 1000-line check_file_size.py cap. main.c retains main(), demo_pins_init and demo_panic_halt; it reaches the worker side only through ThreadX's tx_kernel_enter -> tx_application_define linkage. ThreadX's tx_api.h declares that kernel hook, so this header exposes only the descriptor arrays shared between the two sibling implementation units.

This split is a pure, behaviour-preserving code move: no logic was altered.

Enumeration Type Documentation

◆ tz_secure_only_usb_hs_descriptor_len_t

enum tz_secure_only_usb_hs_descriptor_len_t : uint16_t

Byte lengths of the four USBX descriptor frameworks.

The descriptor byte arrays are defined in the sibling translation unit tz_secure_only_usb_hs_descriptors.c and consumed by demo_worker_usbx_init in tz_secure_only_usb_hs_steps.c. Because an extern UCHAR foo[] declaration alone is incomplete in the consuming TU (sizeof would not compile), each array is declared with its explicit dimension below; these enum members name those dimensions so the declarations stay magic-number-free. The defining TU static_asserts each value against the real initializer length, so any drift is caught at compile time.

Invariant: Each value equals sizeof of the matching array.
