USB superspeed peripherals Forum Discussions

what is the recommendation design/connections for FX3 with a Type-C receptacle when using a USB 3.1 Type-A to Type-C cable to connect from PC host to FX3? Basically we just need FX3 able to transfer data between PC Host and the FX3 board device with using Type-A to Type-C cable.

Hi,
I added CyFxUSBSerialNumberDscr in my descriptor file and I can see the serial number in Control center.
but in cyusb_linux, I can see always 3 which is the serial number string not what I set, is there anyway to see the serial number that I set in FW in cyusb_linux?

Thanks

Hello , i use the example above example found in D:\EZ-USB FX3 SDK\1.3\firmware\cx3_examples\cycx3_uvc_ov5640.

I do not understand where is the deserializer initialized, where is configured?

Also i would be interested in using another image sensor like AR0220 or OX03A10, so what should i do?

Hello,

I'm trying to gather MIPI stream from a custom module using CX3.
Now, I'm able to gather images but I think they have a timing issue.
I tested it using the PN9 test pattern and the symptoms are below.

When I first acquire an image, there is nothing wrong with it.
However, after some time has passed, distorted images are acquired.
Then it comes back to normal a little later.

Below is a normal output image.

Below is a distorted image.

Below is my "CX3 Receiver Configuration".

Are there any wrong settings? and how can I handle them?

or do I need to perform process like skew?

I am trying to capture SOF events but need to know the ID of the SOF event.  I am able to successfully execute code in theCY_U3P_USB_EVENT_SOF_ITP callback. 

After CyU3PConnectState, I call

	/* Enable SOF events */
	CyU3PUsbEnableITPEvent( CyTrue );

I get my events in the callback,

	case CY_U3P_USB_EVENT_SOF_ITP:
	{
	//      Always zero.
	//	uint32_t DEV_FRAMECNT = *((volatile uint32_t*) 0xE0031404 );
		uint32_t DEV_FRAMECNT;
		CyU3PUsbGetDevProperty ( CY_U3P_USB_PROP_FRAMECNT, &DEV_FRAMECNT );  //also always zero.
		if( DEV_FRAMECNT == 0 )
		{
			gbSOFToggle = !gbSOFToggle;
			CyU3PGpioSimpleSetValue( GPIO_SOF_NR, gbSOFToggle );
		}
		break;
	}

According to the datasheet, the register DEV_FRAMECNT should contain the SOF id of the last SOF, but whether I use CyU3PUsbGetDevProperty  or read directly from the register, it's always zero.

Do I have to do something to enable the framecnt register?

Hello，

I had success debugging with jlink before, but two days ago I had a problem with my computer and I reset my computer.
I reinstalled EZ-USB Suite and jlink, and now I can't debug after configuration. EZ-USB Suite doesn't open jlink automatically when I start debugging, but it would before, did I forget any important settings, please help me.

My configuration is as follows, CX3's jlink debugging settings should not be a problem

Hello, I want to read the deserializer register but it is not working, can someone to help me? Thank you.  With I2C_SLAVE_ADDRESS (0xA0u) is working fine but with deserializer adres (0xA4u)it is not.

Hi!

I am planning to use two MIPI sensor modules in my application (2 MIPI lanes per module). What would be the best way to connect both of them to a single CX3 controller?

Thanks!

hello all.

I'm a newbie so my question might sound trivial.

I'm trying to get my ARM-USB-TINY-H to debug through jtag a cypress FX3 on a custom board.

I've succeeded to flash out an example to the FX3 using the USB3 connection, but it doesn't have debug capabilities.

can anyone point me to the right direction on how to get it to work?
