Hi everybody;
I am writing a test program for USB device (CDC class) on STM32F407 With ARM MDK V5 IDE.I'm using The USB-OTG-HS as FS (PB14 PB15); I used the deliverd examples by modifying thePHY interface to ON chip full speed PHY.But no way to Make it Work: No enumeration (Unrecognised Device IN Win10).Though the test works well with STM32CUBEIDE.I tried evrything ; I need help.
Best regardsChiali.
Hi Milorad
It's perfect. Thanks a lot for your help.
It was in the SystemClock_Config (RCC_OscInitStruct.PLL.PLLM = 8U; instead of 25U initially).
Best regards.
