There was a problem hiding this comment. The PLL statements in all board.hpp could be moved above the 👉🏾 This would document the causality and the "...Usb requires 48Mhz..." assertion somewhere else in modm would have catched me! Something like this: There was a problem hiding this comment. Ohhhhhhh, that's an excellent idea!!! I'll merge this first, then prototype it. We can probably also put the AHB/APB prescalers in there. There was a problem hiding this comment. Something easy, to build up 'momentum of success' will also support my motivational chemistry to complete the old graphic related PRs. There was a problem hiding this comment. I've quickly sketched this in #1137 |

Is this correct?

I've setup a PWM on Timer10 and Timer11, confirmed the output frequency and looks fine.
But could not make USB / TinyUSB working.
Please give me some advice!

That's cos the USB is running at 50MHz and not 48MHz, hence my question about whether this clock is correct ;-P It probably works for a short time, but then gets out of sync.
CubeMX shows this solution running the CPU at 96MHz and USB at 48MHz:

Actually, the /Q prescaler isn't set at all, so the USB probably runs at 100MHz or something completely wrong.

Ok, i have not really tried to iunderstand the clock system yet. So i got a copy of CubeMX as it looks like an usefull reference. Have seen this graphical configurator before but your screenshot finally convinced me to give it a closer look, thanks!
USB now works 😄

I swapped the prescalers to align with the CubeMX solution, so the CPU now runs at 96MHz and the USB still at 48MHz.
