Hi! I have several questions regarding standard USB host implementation.1) Host mode: File "stm32f4xx_ll_usb.c", function "USB_HC_StartXfer" there is a piece of codeif (dma == 0U) /* Slave mode */ { if ((hc->ep_is_in == 0U) && (hc->xfer_len > 0...
I'm unable to get the USB peripheral to work on this chip. For some reason even the USB_FS_IRQn won't fire. This chip has no external vbus detection or VDDUSB. I checked PWR CR2 USV is 1 and I can have the host detect the device by controlling the us...

I have used testing for STM32F413 Discovery kit board but Audio_playback_and_record example is a lot of error. So, I want to take this same example for acoustic. Because I process project for acoustic device. Unfortunately, I could not be found at al...
In device's errata sheet , we've found a statement 2.2.13 which says that MCUs with system bootloader V9.2 is not functional .But MCUs with system bootloader V9.5(date code after W05 2020) is functional.As of today ,for R&D purposes , we have 15 cust...
Hello! I am working on designing USB audio class 2.0 device, based on stm32f722 with high speed USB external PHY USB3300. In USB audio class 1 mode the device works fine, but in UAC 2.0 mode device enumeration fails. Device descriptor and USB analyze...
It looks like ST is changing the Cube MCU packages. Up to version H7_1.7.0 the old-style huge packages can be found on github (https://github.com/STMicroelectronics/STM32CubeH7/releases). But HAL drivers since v 1.8.0 are in a separate repository (ht...
(there was a failure while reading analog voltage from a pin board is shut down and pluged out the ST-link connection.10s of secs it wouldnt boot and after a waiting and plug the power it booted and i can program it without any problem but). when i c...
