USB superspeed peripherals Forum Discussions

Hi,

I have designed a board with an USB FX3 SuperSpeed chip. There is a small uncertainty in the working of the board when I use the 1.3.4 version of the ET USB Suite. The cause of the erroneous behavior is in the spi driver code.  I have found out that the board works fine with the 1_3_3 version of spi driver. I have the source code of the 1_3_4 version, because it can be found in the c:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\firmware\ directory. Unfortunately from the Infineon site only the newest version can be downloaded. In the newest version only the precompiled version of 1_3_3 driver can be found in the c:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\fw_lib\1_3_3\fx3_release\ directory. This is how I could try out the 1_3_3 driver. It would be nice to compare the two source codes, to find out what causes the error. So I wonder, if the fx3_sdk_1_3_3_src.zip file can be found somewhere.

Hello,

I used an an75779 based firmware in a Windows environment to set up an image sensor through a StreamerExample device.
Once the device was driver bound to the StreamerExample device, it was able to load data into bulk endpoints using CYAPI and send it to fx3.
However, when I tried to port the application(using CYAPI) to the linux environment, I could only see one cypress device with the lsusb command.

$ dmesg

$ lsusb

How to use StreamerExample Interface in AN75779 Chapter 5.9 on Linux?

I read the data(Community, KBA, Docs...) about CDC and extension unit, but I don't understand exactly if they apply to this situation.

Attach the firmware that connects to two devices in Windows.

Thanks.

Hi, 

I am trying to load a text file onto the cypress CY7C68013A  after I have flashed the firmware onto it, and then stream data from it using a separate endpoint to a slave ASIC using external GPIF signals. I am unsure about the approach to follow, as I am not clear on how the existing firmware will access the data that is stored on the RAM.

.Any guidance on this issue is helpful.

Hello all,

               I followed this KBA https://community.infineon.com/t5/Knowledge-Base-Articles/EZ-USB-CX3-Interfacing-with-the-onsemi-AR0234CS-sensor-KBA236855/ta-p/402602

               and able to stream y8 successfully but what is the way to stream y10 from AR0234, I planned to stream either y12 or y16 but only y8 and y10 is supported by Ar0234, If I use AR0234 configuration data for streaming y10 from sensor, what is the configurations do I need to do in CyU3PMipicsiCfg_t structure and GPIF bus width on CX3 side.

And is there any application which supports streaming y10.

Normally i used header in order to have image information but with IMX412 , it does not work and i  set header size to zero but my information that i filled is contained in the image .

How can i used this header functionnality with IMX412 ?

Is sensor able to manage this functionnality ?

Hello，请问如何自定义GPIF对应的数据总线pin

脚，选八位宽度会自动选择GPIO0-7，而且在GPIF Designer软件中不可更改。

Hello Infineon!

I'm attempting to add CDC ECM and RNDIS to an fx3s, I'm wondering if it's possible to get feedback for when a USB configuration fails and to let FX3S attempt a second configuration?

The idea being that if CDC ECM fails, it then tries configuration 2 which is RNDIS? I know there are no samples for CDC ECM or RNDIS, but is there an example for how to switch configurations on FX3s?

Regards!

Hi,

I'm new to the CYUSB3KIT-003 from Cypress. I've started reading the manuals in order to understand the device, however it seams to become a bit overwhelming.

I'm wondering if it is possible to design a firmware to transfer data through bulk and isochronous endpoints as well as using UART and I2C, all at the same time.

If there are any hints or specific documentation that I should read, please help.

Thank you!

I "read" on this forum how to implement a 24-bit uvc rgb888-based on the AN75779 and followed all the steps for that solution based on the AN75779 YUV2 example, but when I increase it using amcap.exe, I still get a black screen. Attached here is a chip image of the FPGA video stream and a screenshot of the AMCAP.exe. Please help me to solve this problem.

Hi,

I am using the FX3 driver in my device and at some point while running the software, the board has a communication timeout/failure. The code uses multiple threads: a) thread for requesting data from a GPIF endpoint, b) for parsing the data and c) for plotting the data.

What might be the possible cause or event in which the xferdata returns a false value? 

Thanks,
