Hello,

SPI interface (SPI_SCK,SPI_SSN,SPI_MISO,SPI_MOSI) in fx3 works only for booting(4 bit wire interface with spi flash).I cant use these (with another CHIPSELECT )spi controller for other slave (example zynq as slave controller).

if i do this interface,fx3 booting is going to fail.

what is the reason?

Thank you.

Hi Sridhar,

I have just checked with onsemi, theAptina MT9m114 image sensor used in the AN75779 reference code is already in EOL. The latest MT9M114 eva board they have is using different interface, which mean there is no way to test out the AN75779 firmware whether can work with MT9M114. Please advise

The MT9M114 eva usd in AN75779:

https://www.ebay.com/itm/Aptina-MT9M114-55CSP-Demohead-Rev2-Board-CMOS-/283446418824

====Old Mt9m114 eva board====

The connection is similar with the Aptina interconnection board

This model already EOL

====New mt9m114 eva board======

The connection is diff with the Aptina interconnect board.

This model is still in production

I want to implement loopback that is based on slavefifosync project, but my customized fx3 hardware supports only two flags connection on pins (G7 & G6),

but loopback source code uses 4 flags (flaga, flagb, flagc & flagd). Can I make loopback source code work with only two flags (example: flaga(full flag), flagc(empty flag))?

If yes, what changes should I do in the source code and pin configuration? And what do you suggest about this approach.

Hello,

I want to reset the Ez fx3 by a vendor command and adding a CyU3PEventSet inside CyFxSlFifoApplnUSBSetupCB makes the firmware programming longer. What M I doing wrong? Thanks

Hi,

I'd like to go further with this previous discussion : is there a way to process automatically, ie in program or scripts rather than with "manual" operations ?

Thank you for your help,

Best Regards

Hello Chandran,

- Right click on the device in the device manager and select 'Update Driver Software'.

- Choose 'Browse my computer for driver software'.

- Choose 'Let me pick from a list of device drivers on my computer'. Click on 'Next'.

- Choose 'Have Disk'. Click on 'Next'.

- Browse to the following directory.

C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\driver\bin\<OS>\<Architecture>

and point to the cyusb3.inf file.

This directory will be present if the FX3 SDK is installed. Please refer to the below link for the same.

  Hi,Srinath S：

                    I designed one IO board use CYUSB3014,the VDD and AVdd  need  1.2V.I use spx3819m5-1-2 chip apply 1.2V voltage and 500mA current.But after tested,I found that it didn't work.I use TLV62130RGT chip provide 1.2V 3A ,it work.I found that Icc need 200mA and Icc USB need 60mA on the datasheet.Is it static work power?

Hi Cypress team,

I 'm getting performance issue when I'm using the cypress driver(bulk endpoint) for the streaming.

Even if my laptop is not the most powerfull computer, the streaming works perfectly at 30 fps (2MP raw8, 62 MBytes/s) but when i set the speed to 60 fps (124 MBytes/s), i'm getting many errors with the function CyU3PDmaMultiChannelCommitBuffer.

Can I get better result if i m trying to use UVC and put my raw 8 into a format allowed by the UVC driver ?
