So, i need to save raw datas (raw 8 bit, YCpCr 4.2.2 ) coming from a camera (USB 3.0 UVC+CDC)into a standard UDISk (USB 2.0 HS or USB 3.0 MSD). The CDC is used to set the camera up via mavlink commands). 

The data throughput  is low, (around 6 frames per second at VGA resolution) but still the interface has to be USB 3.0, because the camera manufacturer did not develop an USB 2.0 interface yet. 

Regarding the UDISK, i am free to use either USB 3.0 or USB 2.0 HS (USB 2.0 FS maybe would not make it in term of throughput). 

So i am looking for the ideal SoC/chip to perform this task, provided that there is no processing at all to be done on the data themselves, the datas should just be stored, raw, on the udisk. However the SoC/chip will have to set the camera up via mavlink commands (under CDC) and possibly drop some frames, depending on the user settings (so it will effectively save 3 to 6 frames per second on the storage).

There is no connection to PC required, this is just a basic standalone system, user setting will be retrieved from a file inside the udisk. Temp range -20°C +70°C. 

What SoC of chip do you advise? is the FX3 suitable or is there some better fit? Ideally i would like to avoid having a separate MCU, single chip solution is prefered. 

Hello Folks,

I am working with Cypress c# streamer to receive the images. The application is streaming continuously without any failures. But I am not able to receive the clean pictures. There is a continuous distortion in the images that I am receiving. I have attached sample pictures for reference.

Please guide me on this. How can I resolve this issue?

Hi,

Hello,

I am facing Controller hang during SPI data transfer, through uart prints i was able to see function is entering into the SPi wrapper function we built but it is not exiting or returning from the function,

Please find SPI function below, this will be called from the wrapper for each byte of the data that has to be written

/* SPI read / write for programmer application. */
CyU3PReturnStatus_t
CyFxSpiTransfer (
        uint16_t  byteAddress,
        uint16_t  byteCount,
        uint8_t  *buffer,uint8_t  *readBuffer,
        CyBool_t  isRead)
{
    CyU3PReturnStatus_t status = CY_U3P_SUCCESS;

    if (byteCount == 0)
    {
        return CY_U3P_SUCCESS;
    }
        if (isRead) /*Read*/
        {
			CyU3PSpiSetSsnLine (CyFalse);
				status = CyU3PSpiReceiveWords (&readBuffer[0], byteCount);
				if (status != CY_U3P_SUCCESS)
				{
					CyU3PSpiSetSsnLine (CyTrue);
					return status;
				}
			CyU3PSpiSetSsnLine (CyTrue);

        }

        else /*Write*/
        {
//            CyU3PDebugPrint (2, "STFE\n");

            CyU3PSpiSetSsnLine (CyFalse);

            status = CyU3PSpiTransmitWords (buffer, byteCount);
//            status = SendSpiWords(buffer, byteCount);
            CyU3PDebugPrint (2, "STF-%x\n",status);
            if (status != CY_U3P_SUCCESS)
            {
//            	spi_deint();
                CyU3PSpiSetSsnLine (CyTrue);
                return status;
            }

            CyU3PSpiSetSsnLine (CyTrue);
        }

    return CY_U3P_SUCCESS;
}

please find the UART prints capture

Thanks and Regards

Hello,

We are currently in development of a product implementing HX3 CYUSB3304 USB hub. We set the hub as I2C slave to be configured from an external I2C master according to article KBA90943.  In case if we send whole config data created in HX3 Blaster Plus via I2C  hub successfully enumerates in system  and then become "silent" for new data requests via I2C .  All next commands are ignoring,  hub not putting "ACK" after master's transmission it address (0x60).  Same behavior if the first command is not page writing  with valid data array and in that case reset for CYUSB3304-68LTXC  is required for make it work (after proper data upload, of course).
Is it correct behavior of the chip? If yes, why so many I2C operation described in the KBA90943 article?

In our product we need dynamic port reconfiguring and will be good to make it with no chip reset and whole settings uploading, just updating one byte... is it possible?

Thanks,

Roman

Hi Infineon

Which OS and Systems can support for CYUSB3314-88LTXI? Is it include Raspberry Pi (HW/OS)/Apple/Linux too, Thanks！

Hi,

Can you please advise if  the upstream port for HX3PD could be dual role, sink and source?

I could just find this old post during early stage of this product, so I'm wondering if this is now implemented.

I'm currently reading back and forth the Datasheet, AN91378 and EVB CY4613 schematics but was not able to find:

•  If not using pin strapping and go with the defaults - what is the polarity of the power switches - active low?
• the CYUSB3326 has two shared ports - are they activated as "shared" by default? - because Tab8 in datasheet says EEPROM default is b'0000 == disabled
  • if I need to activate the shared function using EEPROM config - I would tend to configure HX3 as a slave (with our SOM as master) - are those settings permanent? I expect that I have to cycle the USB power after writing to HX3 - but as an embedded device it is connected to the same supply as the SOM module and I don't want to cycle its power/reprogram it on every start up (which causes problems if we connect a bootable stick to this hub)
