Hi,
I developing firmware that can stream data at 720p@30 fps. Input format is RAW10. As RAW10 is not supported streaming for windows, I have experimented with two configurations using reference from the below link. As we want higher resolution as our next goal we want higher throughput. We want to go ahead with the second option. But we are unable to stream 720p@30fps.
Streaming RAW10 Format Input Data to 16/24-bit Output Format in CX3 MIPI CSI-2 - KBA224387 .
1) Experiment 2: 16-bit output data format (CY_U3P_CSI_DF_YUV422_8_2) in which Streaming is Working
Here is MIPI receiver configuration.
Here is the descriptor and MIPI configuration.
2) Example 3: 24-bit output data format (CY_U3P_CSI_DF_RGB888) in which Streaming is not Working
Here is MIPI receiver configuration.
Here is the descriptor and MIPI configuration.

I am looking for an equivalent form of the FindPin Function in Video for Linux that will allow me to send a trigger to a UVC camera that is attached to my computer by USB. The camera has a FX3 chip inside. The camera is compatible to stream in Linux with no problems already. The stillpin works correctly in Windows and can trigger the camera sending the commands to do so. I am looking for the equivalent of this in Linux. I am making a QT creator application in Linux that will simply stream video on a GUI and have a trigger button, when pressed on the GUI it will send a trigger command to the cameras pin and will capture an image from the video stream.
Show LessHi Cypress Experts:
I am trying connect camera with ISP to CX3, but no image output.
The ISP output MIPI setting as below:
The CX3 configuration as below:
Could you please help to check whether there is anywhere un-reasonable?
Here is the log:

Show LessIs there a USB-Serial Bridge Controller that supports USB3.0?
Or, do you have a plan for that product?
CY7C65213 is USB 2.0 certified, so I just want this 3.0 certified version.
Thanks,
Tetsuo
Show LessDear supports,
we want to use memory in normal operation F/W (280KB) + backup F/W (280KB).
During normal operation, only F/W (280KB) is used. If there is a problem with the F/W in the EEPROM, we would like to be able to boot to the Backup F/W.
(Only one of normal operation F/W or backup F/W)
Currently, we understood that the use of 256KB EEPROM 2EA in FX3 is the limit specification.
However, the EEPROM memory-related restrictions on the FX3 document have not been confirmed and the reason is unknown.
Please answer the following questions.
- 1. Reason for FX3 + 256K EEPROM 2EA limit specification
- 2. Whether FX3 and EEPROM can be used as follows.
1) FX3 + 512KB EEPROM 1EA
2) FX3 + 512KB EEPROM 2EA
Best Regards,
Tony Kim

I referred AN4053 Streaming Data Through Isochronous or Bulk Endpoints on EZ-USB® FX2™ and FX2LP
I followed the chapter 2 Associated Project Files, I unable to create hex file and I share the screenshot below
Thanks
Esakki
Show LessPlease send me link for FX2LP programming guide.
for example: CPUCS = 0x02; //12MHz operation , CPUCS[4:3] = 10.
PINFLAGSAB = 0x08; // FLAGA - EP2EF
for Reference programming guide How to set hex value for clock or set port ? with explanation

Show LessDear Cypress,
Write data to Storage Port(through FatFs):
I was running the cyfx3_fatfs example code on FX3S board, where am using write command
FX3S: `write` sample
Above command works fine and able to write raw data to that sample file and by defaults, it writes 20MB data, next what I did was executed the same command
FX3S: write sample1
this time while writing the data I just removed the SD card and it hangs.
Would like to know do we get any error from f_write?
if we are removed the SD card and it is blocking in f_write.
Thanks,
Vijay
Show LessHi all,
I want to setup many producer to many consumers as below:
1. CY_U3P_UIB_SOCKET_PROD_2 and CY_U3P_CPU_SOCKET_CONS. DMA channel create mode is CY_U3P_DMA_TYPE_MANUAL_IN. this is for receive endpont 0x02 data for fx3 do command passer.
2. CY_U3P_CPU_SOCKET_PROD and CY_U3P_PIB_SOCKET_1. DMA channel create mode is CY_U3P_DMA_TYPE_MANUAL_OUT. this is fx3 passer command to write data to extern FPGA with P-port( use GPIF II master desgin )
3. CY_U3P_PIB_SOCKET_0 and CY_U3P_UIB_SOCKET_CONS_6. DMA channel create mode is CY_U3P_DMA_TYPE_AUTO. this is fx3 passer command to read data from extern FPGA with P-port.
4. CY_U3P_CPU_SOCKET_PROD and CY_U3P_UIB_SOCKET_CONS_6. DMA channel create mode isCY_U3P_DMA_TYPE_MANUAL_OUT CY_U3P_DMA_TYPE_MANUAL_OUT. this is fx3 passer command to send data from cpu to endpoint 0x86.
In my case, i use CyU3PDmaChannelDestroy function to transform dam mode but destroy dma need to spend too much time
How do I choice which use multi channel DMA mode to design for my need?
all
Thank you!!
Show LessWhen EZ-USB CX3 is powered by USB, how to judge whether CX3 is in normal working state? When the USB is connected to the computer, the computer does not respond, that is, it fails to enumerate the USB. What should I do?
