10 / 28 page 10 7618C–AVR–07/08 Figure 4-1. Example of Firmware Download Zero Length DFU_DNLOAD Request The Host sends a DFU_DNLOAD request with Zero Length Packet (ZLP) to indicate that it has completed transferring the firmware image file. This is the final payload packet of a download operation. 4.6.1.4 Answers from Bootloader After each program request, the Host can request the device state and status by sending a DFU_GETSTATUS message. If the device status indicates an error, the host must send a DFU_CLRSTATUS request to the device. 4.7 Reading the Flash or EEPROM Data The flow described below allows the user to read data in the Flash memory or in the EEPROM data memory. A blank check command on the Flash memory is possible with this flow. This operation is performed in 2 steps: • DFU_DNLOAD request with the read command (6 bytes) • DFU_UPLOAD request which correspond to the previous command. OUT Prog_Start + (EP0 fifo length - 6) x 00h SETUP DFU_DNLOAD OUT X offset bytes + Firmware Packet 1 OUT Firmware Packet 2 OUT Firmware Packet n + DFU suffix IN ZLP |
