 I am having issues using the CyControl program to progam the I2C Serial EEPROM on my development system.  It appears to function properly (checked I2C scl and sda with oscilloscope) but it always results in a failure.  Does anyone have any ideas to help solve this issue.  This approach works fine with programming an SPI Flash that is also on my evaluation board but in my final design it needs to download from the I2C Serial EEPROM.

System:

Xilinx Virtex 7 VC707 Evaluation Board

Inrevium TB-FMCL-USB30 Mezzanine Board with Cypress CYUSB3014 USB3 with 1Mbit I2C Serial EEPROM

Hi,

Using this application note and suitably modifying the uvc descriptors and sensor initializations, I have been able to get video at resolutions till                    3264 by 2448 (approx 8M).  But I am not able to get the full 10 M video that the sensor has capability for (3664 by 2748).  Is there a limitation on the size of video that I can stream through this setup.  I am ok with reducing frame rate to less than 5 also if that's what it means to get this working.  I tried the same by modifying the UVC descriptors but have not had luck with this so far.  Thanks in advance for any pointers on this.

What is the recommended pad size for the FX3S BGA footprint? (pad diameter)

Currently I am using 0.45mm diameter in my designs - is this suitable (given that the balls on the package are 0.3mm diameter)?

Thanks.

I am using the GPIF Master example from http://www.cypress.com/?rID=84236.  I have it working nicely in USB2 for normal MaxPacket Length packets.  If I want the DMA/State Machine to send a short IN packet what should I do?  I know before hand when the FPGA connected to the GPIF bus will just send a single word to the Cypress and at this point I need to make sure the USB Controller just takes this single word and sends it back as an 4 Byte Short IN Packet going to the PC. 

Or could I use a Cypress input from the FPGA to "force" the Cypress to send a short packet with the data it has its buffer?

Hi all,

up to now we had worked with a FX3 DVK Board connected via Samtec J77 to a FPGA Board without problems.

Now with our custom board the FX3 does still successfully enumerate with Cypress 04b4:00f3 id on power up.

But then after we upload (any) firmware via USB (without error) at the end FX3 disconnects and never comes back!

Any ideas what could be the reason?

Best regards

Dear Sirs,

I connected GPIF databus to LEDs for viewing data, and I wrote firmware to pass data on P-port (GPIFII). But there are not data. Use of CyU3PGpifWriteDataWords() API, sockets is unsuccessful. I just want drive data on databus now, but It doesn't work. I use Master Asynch mode without input signal. What is wrong?

Also, I tried RSKV's example GPIF_EXAMPLE2.zip, but when I program FX3 device, the device is not recognized, and usbview.exe doesn't see any device.

 Hi All,    

The firmware libraries and examples from all previously released versions of the FX3 SDK are archived at:    

http://www.cypress.com/?rID=86575     

Also, now you can roll back to older version of the FX3 SDK with the help of “Cypress Update Manager”, if required.     

Thanks,    

Sai Krishna.
