Posted on May 17, 2011 at 12:53I have successfully used the Device Firmware Upgrade (DFU) USB demo application. I'm able to program my main application through a boot loader using this method. I'm also able to program external serial flash as a second target. I'm wondering how to determine how much data will be coming down to be loaded into my serial flash. I can watch each page of data coming through, but I don't have a way to know when the last page has been received. Is there a way to know how much data will be coming or when the last page has been received?
