USB superspeed peripherals Forum Discussions

Hi,

We are working with the CYUSB3014 chip and have some questions that we can not find answers to in the datasheet:

* What CTLE settings do the chip apply on RX?

* What settings of de-emphasis and output swing does the chip use on TX?

* Are these parameters adjustable and in that case, how?

Many thanks and hoping for quick response,

Hi,

I'm new to the FX3 kit. I was trying to using FX3 kit for SPI communication. I started it with running sample code "cyfxspiregmode.img".

In the USB control center, SPI flash seems can be wrote only once. It will show "CONTROL OUT transfer failed with Error Code:997" when I want to read or write after the first success.

I think that is because the buffer is fulled, so it cannot be read or written for more than one time.

But I'm wondering if it is possible to send and read message for multiple times? Maybe by erasing the data in the buffer?

Thanks in advance!

Hello

Regarding FX3/CX3 PMODE pin for setting boot option.
Please tell me the input condition when changing the setting of boot mode due to the external input and setting the set value to "0", "Hi-Z", "1 "from the set condition.
Is the terminal a circuit with a 3-state input and 1/2VIN when open due to the internal resistance voltage division of the input stage?

Hi

I am using the Denebola RDK with the CX3. The firmware on the device is the example firmware for ov5640 sensor that came with it from e-con systems. I can see the camera feed in e-cam view on windows and qt-cam software on Linux as well as adjust brightness and other parameters.

I now want to flash a new firmware, however on both platforms I can not get the device to show up on either CYUSB control (linux) or the CYCONTROL center (windows), I also cannot find the device in bulkloop or streamer.

On Linux I have the udev installed correctly and on windows I also have the camera's driver installed and showing up in my device manager (image below). On windows when I first connect the device the derives installed automatically and successfully

I cannot find Cypress BootLoader in the control center and the options to flash the fx3 is grayed out (image below). What am I doing wrong here?

Thanks in advance

Hi,

Is there any updates since 2016 ?

I have the same issue for firmware freshly compiled in latest SDK.

In Ubuntu 18 (Linux ubuntu 5.3.0-51-generic #44~18.04.2-Ubuntu)  "modprobe usbserial .."mentioned above just quits silently with no result.

Hi,

I'm using the super Mutt device which is based on the FX3.

I got a few questions:

1. I'm trying to send user-defined bulk packets using the USBTCD tool- is it possible? is there any API for that?

2. when I'm using the USBRCD tool . I'm getting the following log:

Status success:              10

Status timeout:              0

Status failed:               0

     what is defined as failed? is recovery on the link defined as failed transaction ?

Hello,

I am developing an application there is a requirement that facilitates the SDIO Interface mode from a single-bit data bus to four-bit data bus in runtime.

The application looks like:

1. configure the SDIO interface using 1 Bit mode ( only one DAT[0] line would be enabled) [io_cfg.s0Mode = CY_U3P_SPORT_1BIT]
2. Do some Read/Write
3. Reconfigure the SDIO Interface using 4 Bit mode (All 4 lines, DAT[0] to DAT[3] lines would be enabled )[io_cfg.s0Mode = CY_U3P_SPORT_4BIT;]

How to enable these SDIO lines run-time? If it is possible to do so, will it affect interrupt handling?

SDIO Host: FX3S

SDIO Slave: Embedded SDIO card

Hi!

We are making an updated design of our USB hub solution were we are considering HX3. One customer requirements is that it should support USB Asynchronous audio streaming for their high-end audio solutions. However, we are unsure if that has any dependency on the hub-part of the solution or if it is only a matter for the host and USB-device side? Anything to consider regarding the clock (or similar) for the HX3 and hub?

Cheers

Hi, I plan to interface a python 500 Cmos camera with Cypress EZ-USB FX3. The frame rate of the camera is 500 fps(Pixels:600*800). So I'm just wondering to know if it is possible to achieve 500 fps?

Many thanks,

Frank
