Hey

I am using STM32F429VIT6. I have ported the USB_CDC program from the example and was working fine with the Evaluation board. I have changed the program to work with the MCU and ported the program. I havent enabled the VBUS pin. The compuuter was not detecting the USB. So the next time I enabled the VBUS and connected to the laptop using cable. Again it was not detecting. But after that I am not able to program my MCU using serial wire using St_link. ST_link utility says the target detection failed. lease Help. How should I connect to the laptop to be detected when working as CDC

Hello,

Make sure that you've configured the right pins and check all connections to ST-Link.
