Can someone explain little more about how to build the DFU binary?

[mkcoldwolf]

I've successfully flashed the high memory bootloader into my STM however im having problem building a Binary for DFU According to build for bootloader section Where seems the only step for high memory bootloaders is to build the binary as normal and then upload it via dfu-util However after the uploade complete, it seems that its not running my program and i've checked the boot1 pin is on low But when i flash the binary with st-link normally, it works Any step am i missing? Here i attach the blink led binary. Thanks BlinkPC13.zip
