STM32F4Discovery OTG HS in FS Mode with DMA does not enumerate

Hy STM32 friends,

I am trying to implement an isochronous USB Audio Device with the USB OTG HS Core on the STM32F4Discovery with embedded FS PHY in DMA mode. I recieve the setup telegram over EP0 with DMA but when i try to send the device descriptor the OTG HS core does not send the Data over USB (tested with Logic Analyser). If i switch of the DMA the device enumerates ok. I tested if there is enough free space in the EP0 TxFifo.

txstatus.d32 = USB_OTG_READ_REG32( &pdev->regs.INEP_REGS[ep->num]->DTXFSTS) == 64<br>
<br>deptsiz.b.xfersize == 8

Does anybody have an idea? The fifo configuration is as below:

#ifdef USB_OTG_HS_CORE<br>#define RX_FIFO_HS_SIZE 512<br>#define TX0_FIFO_HS_SIZE 64//128<br>#define TX1_FIFO_HS_SIZE 0//372<br>#define TX2_FIFO_HS_SIZE 372<br>#define TX3_FIFO_HS_SIZE 0<br>#define TX4_FIFO_HS_SIZE 0<br>#define TX5_FIFO_HS_SIZE 0<br>

Hy clive1,

Thanks for the reply

I have checked that the only difference is i didnt define

USB_OTG_EXTERNAL_VBUS_ENABLED which is only used

for the ulpi interface and

USB_OTG_HS_DEDICATED_EP1_ENABLED which i don't use.

Anyhow i tried also with your settings and there is no change.

Regards

Hans Herbert

I have my STMF4 Discovery board working with USB (FS, not HS, I think a PHY would be needed externally).

It works as USB Audio Sound Card and I can also use UART emulation (VCD).

Project is here:

Hi Herbert... or Hans? :)

Did you get anywhere with this?

I also need USB with DMA (HS in FS mode but I need CDC-VCP) and having difficulties.

Thanks,

Cat
