Hello
We are currently attempting to pass the USB3 certification tests in a lab.
So far the tests passed for Windows10 64b & 32b.
But it fails for Windows7 64b & 32b.
We use the last Cypress SDK 1.3.4
Here is the message returned by the certification tool:
It is very strange because Driver and coinstaller were given by Cypress and they manage to get the Windows certification.
Thank you for your help

Show LessHi,
I recently designed a board with reference to SuperSpeed Explorer Kit Schematic.pdf. The cyusb3014 is connected to the PC via the USB3.0 port but nothing happens. I'm sure that the voltages of VDD, U3RXVDDQ, U3TXVDDQ are normal. The FSLC(pull down to gnd) and PMODE(F11) pins are configured correctly. And 19.2MHz crystal can also work normally. So what are the problems that will cause bootloader to fail to start ? Or, is there any way to prove that the chip can work normally? By the way, after power-on, the TCK pin has no reaction, the TDI, TMS, TRST pins are all 3.3V, and the TDO pin is 0.12V.
我最近根据官方开发板资料SuperSpeed Explorer Kit Schematic.pdf 设计了一款PCB,但是当我通过USB3.0接口连接到电脑上却无法识别,我认真检查了VDD, U3RXVDDQ, U3TXVDDQ供电引脚和FSLC和PMODE两个模式选择配置,并没有发现异常,并且19.2MHz的晶振也工作正常,请问还有可能会是什么问题导致CYUSB3014设备在电脑上无法识别,bootloader无法启动。或者说,还有什么方法能证明芯片可以正常工作?顺便说一下,上电后我测TCK引脚没任何反应,TDI,TMS,TRST引脚都是3.3V,TDO引脚0.12V

Show LessHi, everyone
I am using the FX3 to stream video from a image sensor which is controlled by ISP.
The way of ISP control camera,it can showed video in moniter.
By using FX3 EVK CYUSB3KIT-003,the whole video screen is all blank in AMCAP and FX3 show as a camera device in th Device Management. The ISP output data format is 720p@30fps ,YUV 4:2:2. The ISP used GPIF II connected FX3,which used 8bit databus.
Base on AN75775 demo code(http://www.cypress.com/documentation/application-notes/an75779-how-implement-image-sensor-interface-using-ez-usb-fx3-usb), I mark the function about i2c.
When the screen is blank, the uart debug "UVC: Completed 59683 frames and 0 buffers" ,the value of frames is increase , but the buffer count of CyU3PDmaMultiChannelGetBuffer in CyFxUvcApplnDmaCallback function sometime is 0 and sometime is 7652,and the return of CyU3PDmaMultiChannelGetBuffer sometime is 69(CY_U3P_ERROR_ALREADY_PARTITIONED ),what's the problem and how I can solve it?
Something about the GPIF II ,FV is low valid,LV is high valid,so I seted the Polarity of FV is "active low" which is deffernt with the AN75779,and the state machine is changed which red cycle below.
.and then in

I have an OV2775 Sensor with 1928x1088 RAW12 30 fps Configuration. According to the script the Horizontal Blanking is 1622px and Vertical Blanking 38 px, PCLK 75MHz The MIPI CLK Period is 125 Mhz, THS Prepare 48ns and THS Zero 69 ns. I am using this configuration in the CX3:
CY_U3P_CSI_DF_RAW12, /* CyU3PMipicsiDataFormat_t dataFormat */
4, /* uint8_t numDataLanes */
2, /* uint8_t pllPrd */
95, /* uint16_t pllFbd */
CY_U3P_CSI_PLL_FRS_500_1000M, /* CyU3PMipicsiPllClkFrs_t pllFrs */
CY_U3P_CSI_PLL_CLK_DIV_8, /* CyU3PMipicsiPllClkDiv_t csiRxClkDiv */
CY_U3P_CSI_PLL_CLK_DIV_8, /* CyU3PMipicsiPllClkDiv_t parClkDiv */
0, /* uint16_t mClkCtl */
CY_U3P_CSI_PLL_CLK_DIV_2, /* CyU3PMipicsiPllClkDiv_t mClkRefDiv */
1928, /* uint16_t hResolution */
150 /* uint16_t fifoDelay */
I have tried to change the parameters and this is the best result I have got so far. However I still get two big vertical strips in top of my image when I stream it:
Any help will be largely appreciated thank you!
Show LessFX3 / AR0134 Image Sensor – Not working ( Black Screen).
Design is based on App note: AN75779
How to Implement an Image Sensor Interface Using EZ-USB FX3 in a USB Video Class (UVC) Framework
· Using the Cypress (CYUSB3KIT-003 EZ-USB® FX3™ SuperSpeed Explorer Kit)
· Using the extension board (CYUSB3ACC-004) with a custom adaptor board with a AR0134 Image Sensor.
Hardware checklist:
- Proper voltages getting to Custom sensor board adaptor.
- All Clock's look fine.
Software checklist:
- I added code to decode correct Hardware Device ID and turn on LED.
– Inside debugger I made sure it is getting to next step past (SensorI2cBusTest).
- I2C address and registers have been changed and confirmed with logic analyzer. - (I even do a bus decode to confirm).
- Added a test pattern – to know what would be sent out.
Other tests checklist:
- Probing the address bus – I see the data line change per the ( test pattern I’m sending).
- Reading Section 8 of AN75779 – (Troubleshooting)
Added debug switch in the uvc.h file (DEBUG_PRINT_FRAME_COUNT)
Response: UVC: Completed 0 frames and 0 buffers
Counter is at zero and never changes:
Note from app note: If you do not see the incremental frame counter in the PC terminal program, there is probably a problem with the interface between FX3 and the image sensor (GPIF or sensor control/initialization).
Note:
I'm still using the same file (cyfxgpif2config.h) generated from the GPIF editor - from AN75779.
It enumerates correctly and shows up as the correct device FX3 - Using VirtualDub or other camer programs I just a black screen.
Question:
Does this mean I need to make changes in State machine, and I have a timing issue?
I'm not sure how to make the changes needed in GPIF editor -- I have Sensor Spec , but it is under NDA.
Show LessDear Sir/Madam,
We developed one hardware using CX3. We have a Denebola RDK to test our source code. We have one source code which successfully generating PWM signal on Denebola RDK. But same code not working on our designed Hardware. We already did following test cases.
1) Power supply testing on each point are correct.
2) Source code programmed properly on our hardware.
3) Both oscillator connected and working properly
- 13.768 KHz
- 19.2 MHz
NOTE : Hardware schematic are as per the Denebola RDK.
Please let me know how to resolved this problem.
Thanks,
Amit
Show LessHi,
I'm using MAX2084 Evaluation kit, in that kit cyusb2014-bzx driver IC present when power on the board as per the EVM kit instruction. the system not detect. our system windows 7 professional 64 bit.
Show LessHello,
I am using sample code of PWM generation which is provided by Cypress SDK (GpioComplexApp). We are trying to generate same waveform on different GPIO like GPIO 19, 17, 18 but its not able to generate. I go through data-sheet but did not found anything on PWM pin. So, is their any restriction to set the GPIO as a complex pin.
Please let me know why this GPIO pins not able to configure.
Thanks,
Amit
Show LessWhat are the constraints on FX3’s GPIO clocks. There appear to be system constraints when the maximum 100MHz is selected for GPIO on FX3. At what frequency do the constraints start?
I'm posting this question for a customer to see if there's an easy fix before I dig into the issue. I've found similar issues with GPIO clocks on PSoC 6; but not sure how close the PSoC 6 core is to FX3 or HX3.
