Detailed Description

Private diagnostic surface for the EK-RA8D2 audio and USB BSP.

Declares the USB-HS bring-up trail shared by the production translation unit, the host coverage test, and a J-Link bench session. Keeping the declaration in this module-private header gives the externally linked diagnostic object one authoritative type without adding it to the public board API.

Temporary bisect probe for USBHS bring-up HardFault.

USB-HS bring-up step visible to host tests and J-Link.

Stepped through the sub-calls of internal_usbhs_clock_and_mstp + ra8_usb_device_init so a JLink session can read which sub-step is in flight when the worker thread takes the IACCVIOL/PRECISERR fault. Values: 1 = pre cgc_usbhs_pll_enable, 2 = pre mstp_init, 3 = pre mstp_enable(usbhs), 4 = pre ra8_usb_device_init(hs), 5 = post ra8_usb_device_init returned. Remove once the offending sub-call is identified.

Note

File-scope, single-writer (worker thread).

Since

0.1.0

The board implementation advances this value around clock, module-stop, and device-initialization operations. It is volatile because a debugger reads it asynchronously and because every intermediate step must remain observable.

Note

The board worker is the only writer; tests and J-Link only read it.

Since

0.1.0
