USB superspeed peripherals Forum Discussions

Hello,

Im using FX3 CYUSB3Kit-003 on Windows 10, which is the SuperSpeed Explorer Kit. When adding J4 jumper to the board in the device manager it shows up as "Cypress FX3 USB BootLoader Device". Which is fine. After i program the board with my development firmware it uses the Cypress VID and PID from the StreamerExample and thats how it shows up in the device manager "Cypress FX3 USB StreamerExample Device". I am using the driver installed in the following path C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\driver\bin. 

What i want is when i program it with my development firmware i would like the friendly name to be changed to a custom name for the product. When i tried to edit the .inf files in the above driver\bin folder and placed my own string, Windows 10 would fail to install that driver because that new string was not part of the Driver Signature. So my question is this is there a way i can change the friendly name without having to get a certificate and having to submit the generic Cypress driver to Microsoft again for resigning?

Is there a source with more information on the error count fields for the structure CyU3PMipicsiErrorCounts_t as used by the CyU3PMipicsiGetErrors function.  Some are fairly intuitive to me but specifically I'm wondering what the frmErrCnt means.  I'm getting Framing Errors about the rate that the image sensor is configured to send frames.  I'm not sure exactly what the cause is or how to correct it though.  All the other error counter fields are 0.  I played around with phy time delay and can cause errors with sync bytes and start patterns but as far as framing errors I haven't been able to get them to go away.

Any thoughts? 

Thanks.

I am using the EZ-USB FX3 development board. I want to download firmware image to I2C EEPROM, but ,it always show Promgramming of I2C EEPROM Failed.
the EEPROM is 24LC1025.(I tested it with UsbI2CDmaMode,the chip works well )
SW25=off,off,on,on. 
SW40=on,on,off,off.
J42 and J45 pins 1-2 are shorted on the DVK board.
And,the size of img is less than 128KB.   ie  USBBulkLoopAuto.img=121KB
 

Hi:

Hi,

Has anyone ever created an SDK project that I can use to print data read with FX3 into a txt file? - I would like to use the STREAM_IN feature of the device.

Thanks in advance

Best regards

Hi all,

I have observed that the FX3 driver installed with SDK is not completely having the driver for "Cypress USB BootLoader" the default bootloader running with FX3 with VendorID="04B4" and ProductID="00BC" . I have opened the driver "cyusb.inf" file present inside the driver folder of FX3 SDK installation location, I did see that the PID of Bootloader is mapped to "00F3". If this value is "BC" instead of "F3", device is detected properly. So,  Please let me know if there is cypress signed driver with BootLoader assigned to "00BC" or any other suggesstions for solving this issue is also welcome.

Thanks,
