Device Status
Get Status
The Host employs the DFU_GETSTATUS request to facilitate synchronization with the device.
This status gives information on the execution of the previous request: in progress/OK/Fail/...
The device responds to the DFU_GETSTATUS request with a payload packet containing the fol-
lowing data:
Table 4-4.

Description
No error condition is present
File is not targeted for use by this device
File is for this device but fails some vendor-specific verification test
Device id unable to write memory
Memory erase function failed
Memory erase check failed
Program memory function failed
Programmed memory failed verification
Cannot program memory due to received address that is out of range
Received DFU_DNLOAD with wLength = 0, but device does not think it has all the
data yet.
Device’s firmware is corrupted. It cannot return to run-time operations

Index
An indication of the status resulting from the
execution of the most recent request.
Minimum time in milliseconds that the host should
wait before sending a subsequent
DFU_GETSTATUS. The purpose of this field is to
allow the device to dynamically adjust the amount of
time that the device expects the host to wait
between the status phase of the next
DFU_DNLOAD and the subsequent solicitation of
the device’s status via DFU_GETSTATUS.
An indication of the state that the device is going to
enter immediately following transmission of this
response.
