on nand flash using ubi, after the download of the new image into the flash, the "rest" of the nand sectors get erased while flushing the medium. With current u-boot version dfu-util may show: Starting download: [##################################################] finished! state(7) = dfuMANIFEST, status(0) = No error condition is present unable to read DFU status as get_status is not answered while erasing sectors, if erasing needs some time. So do the following changes to prevent this: - introduce dfuManifest state According to dfu specification ( http://www.usb.org/developers/devclass_docs/usbdfu10.pdf ) section 7: "the device enters the dfuMANIFEST-SYNC state and awaits the solicitation of the status report by the host. Upon receipt of the anticipated DFU_GETSTATUS, the device enters the dfuMANIFEST state, where it completes its reprogramming operations." - when stepping into dfuManifest state, sending a PollTimeout DFU_MANIFEST_POLL_TIMEOUT in ms, to the host, so the host (dfu-util) waits the PollTimeout before sending a get_status again.
