STM32L4XX port does not handle STM32_LSCOSEL Topic is solved

Hi Giovanni,

in STM32L4xx mcuconf.h there is STM32_LSCOSEL but in hal_lld.c it is not taken into account when setting up the clocks.

Best regards

Re: STM32L496 USB error Topic is solved

Hi Giovanni,

I have bought a nucleo board and tried to reproduce the problem there without result.
In the end it was an issue with my hardware.

Thanks for your time!

Re: STM32L496 USB error Topic is solved

Can I suggest you set up the scope to look at those signals in differential mode? That way you'll have a better idea of the actual logic levels seen by the CPU. It may be that the data is always one or zero; or maybe there are edges which cause the data to be misinterpreted. Hi Steved, thanks for t...

Re: STM32L496 USB error Topic is solved

Attached you will find a screenshot from sigroc logic analyzer as well as from my scope. It looks like after the data0 of the setup there is garbage on the line. I can't tell if this is caused by the peripheral not doing the right thing or a hardware problem. Here its "SYNC ERR" to the rig...

Re: STM32L496 USB error Topic is solved

Could this also be caused by faulty hardware e.g. bad usb signalling? Does it make sense to investigate in that direction e.g. check the signals and make a trace using a usb protocol analyzer?

Did test against trunk. Same behavior.
