Hi,
I accidentally noticed that FX3's SPI clk voltage is different.
When I use control center, SPI clk voltage is about 1.5v.
And when I use custom FWupdater that is made from our development team, SPI clk voltage is 1.2v.
I'm using register mode and I checked that control center is using DMA mode.
So I was wonder if there is any difference between two modes.

Hello. I am debugging cyusb3014 using segger j-link. Using example code slfifoasync
When when the debugger reaches " status = CyU3PDeviceInit(NULL); " inside of main I get
ERROR: Bad JTAG communication: Write to IR: Expected 0x1, got 0x3 (TAP Command : 15) @ Off 0x1053
This happens immediately after stepping over, or into. I inserted breakpoints as recommended here: Solved: FX3 JTAG SEGGER - Infineon Developer Community
But the issue still persists, as I cannot even reach the kernelentry function to step over.

Hi community,
just wondered about how to connect CYEZUSB3KIT - 003 board with armx64 driven Windows 11 system.
Did not find any suitable drivers within the installation package.
Thank you.
Best,
TBencher

1. OS is windows7
2. FX3 hardware
3. sdk: FX3_SDK_Windows_v1.3.3.exe
4. CDC-driver : 3.13.0.84 in windwos7 for Cypress usb-serial
5. Install driver flow doctment Infineon-USB-Serial_Driver_Installation_Guide_1-Software-v01_00-EN.pdf
Reappearance
1. open video with AMCap, then video is normal;
2. open usb-serial, then the video is stop immediately;
3. we use other computer, the error is the same;
Question
1. We can't use usb-serial and video at same time in windows7.
2. We capture log with Bus Hound tool, attach saving log "win7_first_open_vidoe_then_open_serial_error.zip".
The error log info is 41.0 USTS c0000004 from Bus Hound.

Hi Team
We are facing a thermal issue in our FX3 design.
Due to the board's small form factor, The IC is getting heated up to ~60deg.
As of now, we are powering an FX3 I/O with 3.3V. ( Overall FX3 power supply is 3.3V).
My doubt is if we reduce the power supply from 3.3V to 1.8V of FX3. Whether this change will help to reduce the temperature on the board?

使用python的libusb库读取FPGA通过CYUSB3014发上来的数据,数据的产生速度0.5M/s,表现为FPGA的FIFO长空,但CYUSB3014的FIFO的FLAG_A标志经常拉低(表示CYUSB3014的FIFO满了)。
个人思考了两个问题,一是CYUSB3014的FIFO是否太小了,二是FLAG_A信号是不是与其FIFO真满相比有时延?

Hello @AliAsgar
I am using fx3 super speed explorer kit from while time in ram mode only
so i want to use i2c eeprom and spi flash to flash my firmware
for flashing that what are the jumpers we have to consider while flashing the firmware in fx3 ss explorer kit
i done thoroughly research about its doesnt contain spi flash is it true if it has what are the jumpers we have to taken care while flashing the firmware
Best Regards
Show LessHi,
RAW8/RAW10 - BAYER video to Android Smartphone is a challenge for us.
1. The setting below is incompatible with Android and Windows devices. For example, if I set (RAW10 & 16-bit output), the streaming in the Windows app appeared little green.
2. I try to obtain the streaming using Opencv Library :
A. cap = cv2.VideoCapture(0)
I got Error: CvCapture_MSMF::grabFrame videoio(MSMF): can't grab frame. Error: -2147483638
B. cap = cv2.VideoCapture(0,cv2.CAP_DSHOW)
I got 3 plane Buffer , But i need RAW10/RAW8 Flatten Array for color interpolation algo.
Please advise us on how to obtain RAW8/RAW10 frames without losing quality for windows / Android.

Hello,
I'm still not getting how to calculate DMA buffer size and count for DMA manual IN and DMA manual out for streaming, and one more doubt is do I need to change buffer size and count every new resolution?
