USB Boot Driver
12.13 USB Boot Driver
The USB Boot Driver is implemented as a USB HID class and is referred to as the Recovery
HID, or RHID. The RHID serves as a fail-safe mechanism for downloading and
communicating with application-specific code.
The system is based on two HID Application collections: the Boot Loader Transfer Controller
(BLTC) and the Plug-in Transfer Controller (PITC). Each collection has its own set of HID
reports.
12.13.1 Boot Loader Transaction Controller (BLTC)
The BLTC provides a tunnel to download application-specific PITCs to the local system
memory. The BLTC runs completely from ROM and interfaces directly to the ROM Loader.
Typically, a PITC will be packaged on the host and downloaded through the BLTC and
ROM Loader straight to OCRAM (or SDRAM).
Four HID reports are provided for communication with the BLTC:
The BLTC provides a command/data protocol for downloading code to the ROM Loader.
The BLTC has no knowledge of the contents of the data passing through so, it is really
possible to download anything (not just PITCs).
12.13.2 Plug-in Transaction Controller (PITC)
The PITC is a generic command/data/status tunnel that may be used for any type of
application. The implementation only specifies the HID report structure and the ROM
HID-stack installation for a PITC the protocol implementation is specific to a given PITC.
Typically, a PITC will be downloaded to memory through the BLTC.
Four HID reports are provided for communication with a PITC:
