Hi,As described in these theads (link1 link2), there is a problem in using USB3343 USB HS PHY. I want to use this phy with STM32H743 MCU, but Setting Transceiver Delay (XCVRDLY), did not help. I have generated a CDC example by CubeMXUSBx_DEVICE->DCFG...

Hi,For USB HS device mode DMA to work correctly, we need to consider:1- address alignment (4byte align due to hardware design) ... OTG_D(I/O)DMAx registers2- size of data (not recommended but can be set in byte size using HBSTLEN in OTG_GAHBCFG regis...

Hi,Sometimes (randomly) I encounter a problem in firmware, even though sometimes it works well for hours without any problem.The whole idea of the firmware is that it receives data over USB HS with DMA enabled and initiate a transfer over another int...

Hi,I guess there is a bug in manual clock switching (file: stm8s_clk.c function:CLK_ClockSwitchConfig:( /* Wait until the target clock source is ready */ while((((CLK->SWCR & CLK_SWCR_SWIF) != 0 ) && (DownCounter != 0))) { DownCounter--; }Mus...

Hello,I have some general questions about USB subsystem in STM32F723:Q1- What is the maximum throughput in STM32F723 when working in USB HS with DMA enabled in device mode? with and without USB stack overhead?Q2- Is there any difference in throughput...
