I am using STM32F070RB controller. I did not see DFU loader code for this controller in STM32Cube_FW_F0_V1.9.0 package. So, i have taken some other controllers project and created project for this controller. After flashing the code, DFU device is detecting and Dfuse Demo software also detecting the device. After choosing .dfu file, when i try upgrade, Erase is happening properly. After that it comes download phase and there stuck. Can you please help me in rectifying the issue.
