I have a requirement to design IAP bootloader for STM32F427 based custom board. Can we design such an IAP bootloader which will communicate to DFuse tool using the same windows drivers provided by the ST along with DFuse Software package. I have tried to communicate to dfuse demo gui via usb-dfu class(implemented on device side), windows throws an error "unknown usb, device descriptor request failed". Help or point me where am i going wrong?
