Hi all,
FX3 DVK Samtec to FMC interconnect board (which is shown in AN65974) schematics and Gerber files are attached to this thread.
Thanks,

Show LessHi,
I am using the FX3 DVK board. I want to use GPIF II as a master mode.
Could you provide some GPIF master applications?
particularly for control of sync SRAM's and FX3 as master.
Do you have also samples how to use the API functions CyU3PGpifWriteDataWords() and CyU3PGpifReadDataWords() with GPIF project?
Regards
JW

Show LessHi,
It would be good to get an idea of what data rate people are seeing with the FX3. To help with this I've created a list below
which arranges recorded data rates along with the user name. At the moment Chris_R is at the top, numero uno, on 320MBs while I am second / last on 127MBs - but I plan to improve. If you have carried out any bandwidth tests and would like to share the results please add your name to the list along with the data rate and direction.
Thanks
Chris_R 320MBs - IN

Hi,
I'm trying to configure FlagA to work in U to P mode on Thread 3. Flag should be high if there are 8 or more bytes in FIFO, otherwise it should be low.
I'm having problem configuring this. If I get 8 bytes to FIFO Flag goes high but when I read it it still stays high.
Can anybody advise me how can I configure this?
Thanks for help,
Rok
Show LessHi all,
Please refer to the new application note (http://www.cypress.com/?rID=84341) which provides details on how to get the optimum USB 3.0 throughput, changes required in the firmware and the factors affecting the throughput. Also find the attached firmware example codes which demonstrate the maximum throughput.
Show LessDear guys,
I am a newer in cypress field . And now I should to familiar with how to use USB3 DVK as quickly as possible.
Now I read the EZ-USB FX3 Development Kit quick start-guide.pdf to start my project , and the sdk have been installed in sucess.
however, I do not know how to install the DVK' s driver , because when I plugin the USN cable , there are no notice in my compurer , and when I open the hardware managment center , there are no other devices in USB3 tree.
Can you tell me how to install the FX3 DVK 's driver ?
Thanks!
Show LessIs it possbile to count cycles of system clock and GPIF clock in the firmware?
Hello, in the UVC implementation described in this application note, we are having separate crystal oscillators in FX3 board as well as in the image sensor board. Can we instead have the FX3 clock drive the image sensor's clock so we can do away with crystal oscillator on image sensor?
Since we are already using the GPIF II in synchronous mode with external clock option because the pixel clock from image sensor is used as input clock to the FX3 for video processing, I am not sure if this is possible? Can someone pls suggest?
