Hi
I am attempting to develop application on STM32F469II that utilizes USB CDC.On our HW board, i am able to run STM CubeMX CDC Standalone example.But we are using Keil toolchain, and when running Keil based example - i am not even geting USB RESET (USBRST
). I have exactly the same clock configuration (copied SystemClockUpdate) function from Cube to Keil...What can be a reason for such a behavior where even USBRST is not happening?We are using FS mode of USB and CDC Device configurationKeil driver for USB is 6.8.0Appreciate any help...Igor

Hi igor.igor.002,
Is there any warning or error message ? (the USB wouldn't enumerate then ?) Have you checked the USBRST bit in the OTG_FS_GINTSTS register ? As a test for your hardware, try to run a ready to use example in the STM32Cube and see if it works . -Hannibal-
