Resolved! Next error in stm32f4xx_ll_usb.c?

In function USB_EP0_OutStart is: if (dma == 1U) {   USBx_OUTEP(0U)->DOEPDMA = (uint32_t)psetup;   /* EP enable */   USBx_OUTEP(0U)->DOEPCTL |= USB_OTG_DOEPCTL_EPENA | USB_OTG_DOEPCTL_USBAEP; }In my opinion enabling endpoint should be out of DMA condi...

I have the USART2 setup for RTS/CTS flow-control and Rx DMA for one byte transfers into a ringbuffer. The problem isn't that the ringbuffer is overflowing, it appears that the DMA process is stalled during the erase flash pages operation and the UART...
