Hi,
I am using Cypress FX3 CYUSB3KIT-003 DVK Kit, and cyfxbulksrcsink example firmware is used from the cypress installation directory.
I am not able to run Test_SE0_NAK On cypress FX3 Device, It is not responding with NAK when the test is executed.
Test_J, Test_K, and Test_Packet are working fine.
Can you suggest any thing
Thanks & Best Regards

Show LessI have created one text file (.txt) and now i want it to integrate(path of file) in fx3 main code where should i include that path in code so that that text file should be written into sd card can anyone help me to do this.
Show LessHellow. my name is Younghak Kim
I succeeded in reading and writing data to eMMC memory using FX3SfileSystem.
However, if i use FX3_SMassStorage file to browse for files stored on the eMMC on your computer, you will not be able to see the xx.txt file.
The FX3SfileSystem and FX3SMassStorage are set to FAT32.
What should I modify to make each other aware?
I desperately need your help.
Thank You.
Show LessHi all,
I have question regarding CX3 treating different data type.
Can CX3 receiving different data type at the same time?
For instance,
I have RAW8 embedded data and RAW12 video data, can CX3 receive it at the same time and send it through USB?
Or the video data type should match the embedded data.
Thanks,
Paddy
Show LessHi,
Previously, I booted the working code of FX3 its detecting fine . But after SPI FLASH, i booted the another FX3 code by adding GPIF 2 read and write configuration then reset the device. After reseting the FX3 is not detecting in the U3Z2 board. what may be the problem? If i add the GPIF 2 read and write is wrong?
Find the attached code below, which was booted to U3Z2 board.

Show LessHello
DeneBola (CX3) and J-Link are connected and debugged, but debug error occurs.Please refer to the attached(Debug_error.png) for debugging procedures and error results. Is there anything I can assume about the cause of the error?
Also, I understand that the debug step button cannot be pressed as shown in the attachment( Debug_error2.png)due to an error. But Is there any other possible problem besides this error?
Best Regards

Show LessThe original FX3 U3V sample only supports one format stream, so I tried to add the second format data(multi ROI) within it.
But what's the rule when different format?
It seems that the smaller iamge payload should add 4 bytes padding data when it works with two format?
Show LessHi All,
I believe we are experiencing a Silicon design problem with the CYUSB3064 chip. This is the second generation of the design. We noticed the same issue on the 1st generation, but never got to the bottom of it. This design appears to be worse (e.g. more leakage).
We have a CX3 design that runs VDDIO1 & VDDIO2 from 1.8V, VDDIO3, CVDDQ from 3.3 volts, TXVDD/RXVDD, AVDD, MIPI_VDD and VDD from 1.2V. The board contains four voltage regulators powered by USB's VBUS (5V) whose outputs are: 1.2, 1.8, 2.5 and 3.3V. All the regulator outputs are nominally correct except the 1.8V regulator is 2.7V and appears to be back-fed. The 1st generation boards supply was around 2.1 volts.
With all the components except the CX3 removed from the 2nd generation PCBA, including the 1.8V regulator, the 1.8V supply still sits at about 2.7V. If I connect an ammeter between the 1.8V supply and ground, I measure 15.7 mA, so this is not a dead-short. After removing the CX3 the 1.8V measures zero.
Are we misusing the CX3 in some manner to explain this leakage current?
Thanks,
Scott
Show LessHi all,
I have test setup which consist of Zedboard and SuperSpeed Explorer Kit.
Zedboard with Xilinx Zynq700 FPGA sends test pattern through the parallel interface (CLK/FV/LV/DATA(7 bit)) to FX3 GPIF input
FX3 is connected to PC USB3 port and running example SW from AN75779.
i'm trying to capture video from UVC device "FX3" with VLC/Virtualdub.
Problem is that there are no incoming frames at all.
Here is UART output:
UsbEventCB: Detected SS USB Connection
USBSetupCB:In SET_FTR 0::1

UVC: Completed 326 frames and 24 buffers
UVC: Completed 348 frames and 14 buffers

So video is definitely received by FX3, but is not forwarded to PC.
I appreciate any help
