Hi,I am using STM32F105RC. CubeMX does not seem to configure PLL2 at all in SystemClock_Config(). Below in the clock configurator it is clear that I have enabled PLL2 to be used for PLLCLK and USB clock.Seems like a CubeMX bug. Or if someone can poin...

Hi, I am using a STM32F105RC. I was trying to get SWO printf outputs to work, and found that they only work when I configure HSI (8MHz) to be used for SYSCLK, but not when I configure HSE (25MHz) for SYSCLK. I've confirmed that the external oscilla...

Any updates?

Thanks for creating the ticket. Any idea if the team is working on a fix and when we can expect the fix to be released?

The code snippet you posted seems fine to me, and you will find that exact same code snippet in my original post.However, the problem is that code to configure and enable PLL2 is not being generated. (see line 18 in my code snippet). USB clock uses P...

Thanks for the reply!The PLL is used for USB clock, and I have the USB OTG peripheral enabled. Is it not expected for CubeMX to generate clock configuration code for USB? Or does that clock configuration code live elsewhere?

Hi TDK, thanks for the reply.I am using OpenOCD. I found that the SWO clock frequency was not set correctly, but I don't understand why.Anyways, with a core clock frequency of 25MHz and a SWO clock frequency of 2.25MHz I am able to view SWO output

CubeMX not generating PLL2 code for USB

SWO outputs only works with HSI enabled for SYSCLK, not HSE
