Hi,

If you need to measure time then use the TM API (Time Measurement), no need to use timers and it is clock cycle accurate.

Re: No interrupt generated on USB device connection while USB OTG_FS core is running as USB host only

Hi, When we ported the USB (device) driver to the L4 we had problems because a strange behavior of the OTG peripheral, we had to introduce workarounds in the driver, I don't know if the host mode driver could be affected in a similar way. Your problem seems to be that the driver does not sense the c...

Cache-related problem in some STM32 HAL drivers

Hi, Putting this here to keep track. Several LLDs have DMA-accessible buffers inside the driver structure, this is a problem on those devices where cache coherency must be handled. Required action: move all buffers outside the driver structure, replace those with a pointer to the actual buffer which...

Re: No interrupt generated on USB device connection while USB OTG_FS core is running as USB host only

Hi,

Have you verified settings in board files? those are not tested with USBH and could require changes.
