Hi everyone I did an application board which is containing stm32f405rgt6 but I'm not programming it with stm32f4discovery. I removed the 2 jumpers on cn3 and I did what manifacturer say in ST User Manual UM1457 at page 15. ST-Link Utility is giving warning of "Cannot Connect The Device". Where am I wrong? I'm going to upload circuit when I go to the home..
