UG_12xxF_029 73S1215, 73S1217F DFU Host Driver/Application Development User’s Guide 1 Firmware Upgrade Architecture This document describes the Teridian USB (DFU class) Interface. Figure 1 shows the flow of this architecture. The firmware architecture in this document is a single-threaded C program using the API services as detailed in the 73S12xxF Smart Card Terminal Controller Family Software User’s Guide. The software is compiled and linked using the Keil µVision3 development software.
73S1215, 73S1217F DFU Host Driver/Application Development User’s Guide UG_12xxF_029 2 DFU – Phases of Operation The USB Device Firmware Upgrade Specification Revision 1.1 identified four distinctive phases of operation: 1. 2. 3. 4. Enumeration Phase Reconfiguration Phase Transfer Phase Manifestation Phase This user guide describes the IOCTLs as supported by Teridian’s CCID-DFU driver and DFU driver. 2.
UG_12xxF_029 2.2.2 73S1215, 73S1217F DFU Host Driver/Application Development User’s Guide Attaching the DFU Class Device Upon receiving escape command or dfu_detach, firmware boots up in DFU mode. This time USB-DFU driver (TSCDFU.sys) will be loaded by operating system (if driver is already installed, otherwise a new hardware found wizard will pop up by Windows). See the 73S1215F, 73S1217F Windows XP 32 USB CCID and DFU Drivers Installation Guide on how to install drivers. USB-DFU driver (TSCDFU.
73S1215, 73S1217F DFU Host Driver/Application Development User’s Guide 2.3.3 UG_12xxF_029 DFU Clear Status Request IOCTL : IOCTL_DFUTSC_DFU_CLRSTATUS IN : not required OUT : not required RETURN: NTSTATUS Supported driver : tscdfu.sys SCARD_CTL_CODE(2104) Any time the firmware detects an error and reports an error status to the host in the response to a DFU_GETSTATUS request, it enters dfuERROR state. The firmware cannot by itself transition from the dfuERROR state.
